The project
Nestled between trees and hedges in the municipality of Horgen on Lake Zurich, the detached house from the 1970s provides an environment with plenty of privacy and recreational space: at around 200 square meters, the house is generously proportioned. The project for Raumtakt now consists of converting the single-family home into a two-family home. The family's needs are clearly at the forefront: it used to be a home for two siblings who grew up there, but now they are to live together under one roof in accordance with the latest standards, so that everyone has their own rooms at their disposal. The decision to renovate the house resulted not only from the shared memories and emotional value, but also from the need for sustainability. Raumtakt drew up a comprehensive concept for this, including new windows, no fossil fuels, more environmentally friendly roof insulation and other preparatory work for future interventions. In addition, the building envelope now meets today's energy consumption requirements.
In order to transform the single-family home into a two-family home, two contemporary and sustainable apartments are being built. The space requirements will be adapted to the current needs and circumstances of the residents. In addition, the individual character of the two apartments is made visible through the interior design - and always with future generations in mind. The detached house in Horgen, where the client grew up, was carefully renovated and converted into two modern condominiums. They are designed to create an attractive living experience in a natural environment. The interior design of the two apartments was designed to create a modern and inviting ambience while preserving the original character of the building. Both apartments are generously proportioned and offer enough space for a comfortable living atmosphere. The house is built on half-storey structures and therefore had to comply with the latest sound insulation standards. The upper apartment was accessed via a new external staircase from the north-west side. When redesigning the house, however, it was not only a high demand for contemporary architecture that was decisive, but also the inclusion of the latest standards for energy efficiency and sustainability: a modern air heat pump serves as the primary energy source and the improved insulation of the roof and façade significantly reduces the building's energy consumption. The planning of the conversion also took into account the possibility of installing a photovoltaic system at a later date to make the building even more energy efficient.
Another key aspect of the conversion was the integration of the building into its surroundings: the aim was to create a harmonious connection between architecture and nature. The trees and plants were incorporated into the design of the garden and ensure a pleasant living experience in a natural environment. Overall, the conversion project of the detached house in Horgen is a practical example of how an older building can be modernized to meet the needs of today. The conversion into two modern condominiums, the use of an air source heat pump as the primary energy source, the improvement of the insulation and the preparation for a future installation of a photovoltaic system are measures that make the building energy efficient and sustainable.

What were your reasons for converting or renovating your house?
Built in 1975, our detached house was getting on in years, even though it was well maintained. We wanted to replace the oil heating and windows in particular - and bring all the installations back up to date. We also wanted to divide the property into two apartments.What were your reasons for converting or renovating your house?
Built in 1975, our detached house was getting on in years, even though it was well maintained. We wanted to replace the oil heating and windows in particular - and bring all the installations back up to date. We also wanted to divide the property into two apartments.How long did you think about renovating your house before you decided to do it?
All in all, about three years. There were already various scenarios with other building experts before Raumtakt. Demolition and a new build were also discussed.Why did you choose Raumtakt?
We became aware of Raumtakt on the Internet and saw that the company had already carried out some conversions that we liked.What made you decide to carry out the project with Raumtakt?
After personal contact in which we expressed our ideas, we quickly agreed that we wanted to carry out the project with Raumtakt. They were the only company that was genuinely interested in a conversion and didn't simply want to build a new building.What was your first impression after receiving the quote?
We found it expensive, but after completing the work we are convinced that Raumtakt was an excellent choice. This was mainly because of the cost accuracy and, of course, because the conversion was very successful and met our expectations.What work was carried out as part of the conversion and renovation and how was it implemented?
A complete renovation of the property, new heating, new windows, new electrical and sanitary installations as well as various adaptations to the building according to our wishes (e.g. larger windows, the garage was converted into a room)How did you experience the process of planning and implementing the renovation?
The planning and implementation process was intensive, as it was only in the course of time that various wishes on our part could be taken into account, according to the respective cost status. Raumtakt provided us with very competent support throughout this time and also reliably managed the construction work during the renovation. In addition, Raumtakt works with excellent craftsmen who carried out the work carefully and on time.How important was the sustainability aspect to you during the renovation?
Sustainability was very important to us and we replaced the oil heating with a heating system with an air-heat pump and installed new windows, for example. In a further step, solar panels will now also be installed.Were there any unexpected challenges that you faced during the conversion?
If so, what were they and how did you and Raumtakt solve them? There were situations during the construction phase in which sudden defects arose. Raumtakt always informed us of these promptly and suggested appropriate remedies. Fortunately, there were never any major defects with serious consequences.How were you kept informed about the progress of the work during the construction project?
As we lived close to the property, we were always able to see for ourselves how the work was progressing. And as mentioned above, we were always kept well informed and up to date by Raumtakt.How did you find working with Raumtakt and the craftsmen on site who were involved in the renovation?
The collaboration was always professional and pleasant. If there were any disagreements, these were resolved on a constructive and trusting basis. We would particularly like to emphasize the excellent construction management on site and the very reliable craftsmen with whom Raumtakt works.Were there any cost overruns or delays during the conversion? How was the consultation process?
The cooperation regarding costs was very pleasing and these were kept under control by Raumtakt during the entire renovation. Additional costs caused by extra requests on our part were communicated transparently. There were neither cost overruns nor delays. Overall, Raumtakt carried out this project excellently.How satisfied are you with the result of the overall renovation? Was there anything you would have done differently in retrospect?
We are very satisfied with the result, except perhaps that we should have tackled the renovation with the room cycle earlier.How have the changes to the house affected your everyday life and quality of life?
Positive overall, as the quality of living has been improved, e.g. through new underfloor heating, no more steps between the different rooms, larger windows, new appliances, easy-care surfaces. The new feeling of living is positive all round.Do you have any tips or advice for other homeowners considering a remodel?
We think it's important to realize that a remodel is always a work in progress and that the project continues to evolve even after the planning phase. As a budget was set for our conversion, certain wishes could only be taken into account as the project progressed and this was sometimes difficult to understand in advanceWould you tackle a project like this again? What five valuable tips do you have? What should you pay particular attention to?
A renovation requires perseverance, patience and nerves of steel. We also think it's important to be aware that a renovation is a process that evolves over the course of the project. Trust Raumtakt, they are the experts.Will you recommend Raumtakt to your friends and acquaintances?
Absolutely, we are very satisfied with the result of the renovation and can highly recommend Raumtakt.

The project
Initial situation: The terraced house at Meisenweg 5 in Zurich Wollishofen was built in 1924 and is listed in the special inventory of the city of Zurich. It is part of the Meisenweg estate, a late example of the romantic Heimatstil with cross gables, oriel towers and trellises. The overall effect of the estate is still uniform in design, materials and colors. It forms a closed residential courtyard with front gardens and short staircases. The architect Friedrich Hirsbrunner thus followed the garden city principle of Raymond Unwin and Hans Bernoulli. The builder was the cooperative for the procurement of cheap apartments. The houses are now individually owned by private individuals. Various renovation works have been carried out in recent years. For example, the shell, including the windows, is intact. However, the interior fittings from the 1980s are getting on in years.
Vision: The house is generally in good condition, but should now meet the requirements of a young family. The aim is to achieve a contemporary fit-out standard. The energy efficiency will be improved by insulating and renewing the roof. A switch to ecological heating is planned in a few years' time. The characteristic elements of the interior will be retained. These include, for example, the typical herringbone floors made of beech wood, the striking oak staircase and honeycomb-shaped ceramic tiles in the kitchen.
Implementation: With regard to the insulation of the roof, the opportunity is taken to extend the attic in such a way that the existing square meters can be used as efficiently as possible. Two small rooms and a WC are converted into two large children's rooms with a gallery, a bathroom and a loft. New skylights will bring more light into the rooms. On the upper floor, the bathroom is enlarged and the second kitchen is converted into a room. The two beautiful rooms with herringbone parquet flooring will be refurbished. The first floor will be opened up by placing the living room opposite the dining room. The bathroom will be converted into a checkroom and a guest WC, and the kitchen will be modernized.

The project
Transformation: The new Monami Hub on Europaallee
Anyone who has walked past the corner of Langstrasse opposite the 25hours Hotel in recent months will certainly have noticed it. The conversion of a former nursing home at Lagerstrasse 119 has given rise to the Spät restaurant and, for a time, the Action Burger, but something new has also been created above the first floor. New office space is being created on the upper floors, as well as a restaurant and an audio studio right in the pulsating heart of Langstrasse.
Just the right environment for the up-and-coming PR agency Monami, which is young, lively and creative. The team will use the second floor of the former nursing home as an office for over 30 employees for five years. A spacious and creative workspace of over 400 square meters will be created in a former ward of the nursing home. It will support the agency in creating its content in all colors and forms, be it social media, strategy, consulting or campaigns. An exciting task for Raumtakt.
Workplace: Changing offices
Because Monami primarily creates new content for modern channels, one of the most important concerns was to make the "vibe" of the nursing home disappear. White ceiling lights, hospital doors, linoleum flooring. Raumtakt broke through this aesthetic with lots of color. The partition-like rooms were broken up with wall openings and transformed into an open-plan office.
Nevertheless, there are lockable rooms on the side with retreats for meetings or an after-work beer. The windows of these rooms look directly onto the lively Langstrasse and the Hotel 25hours. The color codes on the doors indicate the use of the respective rooms and reflect Monami's corporate identity. Some rooms were consistently painted monochrome, splashes of color were provided in certain places and the remaining white on the walls was refreshed. This makes the new Monami Office colorful, yet restrained enough to be used by the Monami team.
Fast implementation, low costs
The project could only be implemented in this short time frame thanks to flexible contractors and quick decisions. Predetermined breaking points were staged to give the extension character and, not least, to reduce costs. Ultimately, the aspect of interim use also played an important role in the conversion.
A spacious and creative workspace of over 400 square meters was created in the former ward of the retirement home. It is intended to support the agency in creating its content in all colors and forms, be it for social media, strategy, consulting or campaigns. The rooms and signage are based on the colors of the Monami logo. Raumtakt pursued its circular economy philosophy for this commission: components, lights and glass are to be reused in the design concept. In this way, Raumtakt aims to conserve resources and promote circular construction through efficient project management.

The project
Nestled in the "Globus-Heimeli" housing estate, which was built in the 1930s, this detached house in Zurich-Albisrieden enjoys a unique location: The spacious plot is surrounded by two streams and numerous trees. This means that the residents are surrounded by greenery in the middle of the city. When the house was originally built, this location was not sufficiently emphasized.
RAUMTAKT was commissioned with the conversion and energy-efficient refurbishment of the property on Triemlistrasse. The challenge in converting and renovating the detached house, which was built in 1952, was to create a contemporary and sustainable spatial solution. The new layout of the rooms, which were originally built in the 1950s, created more living space with the renovation thanks to a clever use of the rooms. By removing two load-bearing walls, new areas were gained that corresponded to the modern symbiosis of living and cooking. To support the loads, two steel beams and a column were installed, which, thanks to the clever design of a new spatial solution, make the entire area appear more open. This newly created space also features a multifunctional, custom-made piece of furniture that encases the load support. The furniture can be used differently on three different sides for the kitchen, the entrance area and the living room. The concept of discreet storage options that are integrated into the room runs through the entire house.
A generous opening of the house to the garden and the clever use of a Swedish stove have given the house a modern yet homely touch. The use of the "elements" stove from German supplier Skantherme provides multifunctional design options. The furniture can be converted flexibly, quickly and easily when guests visit, when entertainment devices are used or when the room is rearranged. The Swedish stove is supplemented with a custom-made piece of room furniture that can be used in different ways depending on requirements. This means that the room can always be given a new orientation and design.
With the conversion and complete renovation, Raumtakt Architekten not only created a modern and practical room solution, but also completely renovated the building technology for energy reasons. The heating, sanitary and electrical installations were adapted to today's conditions by combining them in one room. This resulted in a completely new underfloor heating system, the closure of cold bridges and new windows. The pipes for the future solar thermal system were also laid.
The conversion on Triemlistrasse is an example of how a house can be experienced and lived in in a new way thanks to integrated storage options, practical elements and a clever room layout. One focus of Raumtakt, under the direction of business owner Stefan Müller, is the conversion of rooms in existing structures.

The project
Since the first project announcement in 1986 and the official opening in 1983, the Technopark has developed into an important hub in Zurich's start-up landscape and has had a significant impact on the city. Thanks to close links with the technical universities of the Canton of Zurich, the university and the scientific community as well as Swiss technology companies, the Technopark acts as a space for innovation and competitiveness and has already spawned numerous spin-offs. South Pole's headquarters are located in this innovative environment. The company evaluates, develops and implements sustainability strategies and new business opportunities for companies, governments and organizations. With the redesign of its Technopark headquarters, South Pole not only marks an architectural change, but also a symbolic fusion of a sustainable vision and aesthetic innovation. At a time when environmental protection and resource conservation are key issues for companies, this building project represents a turning point. The. South Pole's commitment to these values is translated into architectural reality and set in stone, so to speak.
The challenge: winning the project through a competition
This pioneering construction project did not begin with the award of a contract, as is usually the case, but with Raumtakt's successful participation in an invitation-only competition. Alongside a selection of other architectural firms, Raumtakt came out on top with a unique concept and was awarded the contract by South Pole to redesign their headquarters in Zurich. This competition win not only underlines Raumtakt's expertise and unique selling point, but also the exceptional nature of this project. Reduce, reuse, recycle: Our contribution to sustainabilityThe basic principles of "Reduce, Reuse, Recycle˚ were at the heart of the design decisions for this project. The targeted reduction of material consumption and careful reuse of existing resources not only minimized waste, but also made a clear statement for sustainable building culture. Every step of this conversion contributed to reducing the ecological footprint and using resources more efficiently.
Architectural vision and environmental protection go hand in hand
The deliberate choice of spruce wood as the dominant building material was not only based on a decision for an appealing aesthetic, but also proved to be strategically sensible because it is in line with South Pole's environmental goals. Spruce wood, which has already absorbed CO2, became not only the load-bearing element of the building, but also an active contribution to reducing climate-damaging CO2. Architecturally, the vision of this project manifests itself in clean lines, open workspaces and flexible structures that encourage employee creativity and collaboration. But behind every construction, behind every detail, there is a conscious decision to make a profound commitment to sustainability. This architecture is not just a shell of materials; it is an expression of this responsibility to minimize the environmental impact of building projects while still creating aesthetically pleasing spaces. The redesign of the South Pole Headquarters in Zurich's Technopark combines innovative architecture with an authentic environmental awareness far removed from "green washing" and empty phrases. The "lung", as the new focal point of the office, marks the beginning of a well thought-out spatial concept that integrates the principles of New Work in a micro and macro context. The "lung" serves as a central point and link from which the entire spatial concept originates. Elements of New Work concepts were taken into account in order to create a flexible and efficient working environment and to meet the demands of modern working. The integration of specific work areas that meet the needs of different working styles reflects the contemporary understanding of work in a post-corona society, and a modern ventilation system has been introduced that not only replaces manual ventilation via windows, but also significantly improves the building's energy efficiency. This is particularly noticeable due to the avoidance of ventilation heat losses during the heating period. The installation of a system for heat recovery from the exhaust air reduces losses and significantly lowers primary energy consumption. The office's color concept was developed with the aim of creating a harmonious connection between reused materials and sustainable spruce wood fixtures. By using a light color tone, all reused materials were painted uniformly, creating a clear line in the design of the approximately 1000 square meter office space.
Spruce wood as a decisive element
The CO2-neutral spruce wood fixtures fit into an aesthetic symbiosis by not only serving as sustainable building elements, but also by being seamlessly integrated into the overall design through the color concept. This conscious design decision not only underlines the ecological responsibility of the project, but also creates an aesthetically modern and coherent working environment.
Conclusion: An architectural turning point for environmental protection and aesthetics
The redesign of the South Pole Headquarters in Technopark is more than just a construction project; it is a tribute to environmental protection in action. It is a declaration that sustainable building is not only possible, but highly necessary with the environmental goals that have been set. This architecture not only speaks the language of concrete and steel, but also the language of environmental protection and shaping the future. Together, South Pole and Raumtakt have not only created an office space, but also paved the way for a more sustainable interior design and made it tangible.

The project
The stately house in Küsnacht was planned and built in 1976 by architect Christoph Jung, the grandson of the well-known psychoanalyst C. G. Jung. It is situated on a large green plot with a view of Lake Zurich. Before the renovation, the layout and furnishings were largely the same as when it was built in the 1970s. However, despite the ageing structure, the new owners decided to retain the building they had inherited. However, they wanted a fresh new look for the building. The brief for the conversion of the two-family house in Küsnacht was clearly defined from the outset: The clients wanted to convert the house from a two-family home to a single-family home with a core renovation. The aim was to make it modern and environmentally friendly without completely losing its original character. "However, the ecological aspect was also particularly important during the conversion," says Stefan Müller from the Raumtakt architecture firm.
Keep using it, but do it right - that was the motto for this two-family house in Küsnacht. With a five-year plan for the renovation, the owners and their interior designer are pursuing the goal of turning it into a spacious and more environmentally friendly home for a single family. NZZ Residence, 3/2022 by Nicola Schröder
Raumtakt's building renovations have high standards when it comes to the environmental friendliness of a building. However, it is also important to the architectural firm to meet the client's budget requirements at all times. For the house in Küsnacht, a staggered five-year plan was therefore agreed for the overall renovation. In this main project, the house was converted, with further aspects for an environmentally friendly solution to be added later. "It was important that an architect was contacted early enough and that the planning could be properly implemented". This allowed Raumtakt to pursue the approach of creating a future-proof house with energy-saving measures. But what does future-proof mean? In the first phase of the project, a building physicist was also commissioned to help evaluate environmentally friendly products. In the end, the roof was built with cellulose flakes made from recyclable paper. Triple insulation was also used for the windows. The plan drawn up by Raumtakt now envisages that boreholes will be drilled into the ground in five years' time and that this technology will be used for a new heating system.
"There were clear requirements for the house, such as the kitchen, which was to be semi-open, the number of rooms and the access to the large living room," explains Stefan Müller. To achieve this, he had to make several openings in the house and also work with a carpenter to find installation solutions.

The project
On the top - Raumtakt created a cozy and modern home for a young family on Lake Zurich from an underused and therefore unoccupied attic.
The single-family house with two storeys and a flat roof was built in Küsnacht on Lake Zurich in the 1940s. Around 40 years later, it was finally converted into an apartment building: An upper floor and attic were added to the building, resulting in a gabled roof.
The house had been owned by the family since it was built. The owners, who occupy the two upper floors of the house, also commissioned Raumtakt with the conversion and renovation. The architecture firm Raumtakt was responsible for the overall renovation. During the preliminary project, it emerged that a building mass transfer was required for a further extension to the attic. The calculations for such a transfer are based on the volume permitted for building on a plot of land. This could be fulfilled by a surrounding building. This allowed interior designer Stefan Müller to create an additional living space in the attic that did not previously exist.
In the preliminary project, Stefan Müller worked with the clients to develop a forward-looking spatial program. The aim was to implement the family's vision on the two floors: A clear room structure that offered space for the two children, but also met the parents' needs for a place of retreat.
The clever room layout in the house also met the client's wish for a larger kitchen/living room. By moving a non-load-bearing wall in the kitchen area, the corridor was given a coherent shape. The old, small windows were replaced with floor-to-ceiling, inviting glass. They lend the light-flooded room more comfort and make the rooms appear more inviting. At the same time, this building measure has resulted in considerable energy savings.
The roof insulation of the house also turned out to be inadequate; the entire plumbing, heating and electrical installations proved to be in need of renovation. As the space in the attic was now used as a living area, it made sense to move the heating from the attic to the basement. A plant room was created there; the new pipework in all rooms was used to install underfloor heating.
In addition to the part used as a bedroom with dressing room, a new bathroom has now been added to the top floor. To give the family the privacy they need, Stefan Müller created a stylish glass partition wall with a contemporary industrial look. The glass partition wall with the handcrafted railing in the same black matt finish creates visual clarity and also serves as an eye-catcher in the house.

Through the client JW Immobilien-Kontor GmbH from Munich, Raumtakt was able to represent the client and manage the project for the hotel operator A-ja Resort und Hotel GmbH from Hamburg for almost two years. The project involved the construction of Europe's first A-ja City Resort and one of the largest hotels in Zurich. Raumtakt was able to support the development of 319 hotel rooms with experience zones, a spa, a rooftop garden and the well-known A-ja restaurants in the Vulcano Towers in Zurich-Altstetten. The Vulcano, which was jointly realized by CSA Real Estate Switzerland (CSA RES) - an investment group of the Credit Suisse Investment Foundation - and the total contractor Steiner AG, will give the west of Zurich a new landmark with a spectacular view and impressive architecture. In addition to the relevant construction meetings with CSA Real Estate Switzerland, Steiner AG and various technical experts, we were involved in optimizing the planning as well as in design and construction issues. In addition, we continuously reviewed and commented on the planning documents and the user requirements program, taking into account the tenant's qualitative, financial and time-related interests.
Raumtakt also took on a variety of other tasks for the project: The coordination of the project documentation in the ongoing project and involvement in the selection and awarding of operator services through to the final acceptance of the entire hotel area, which extends over five floors.

P1104. Conversion of detached house. Horgen
Details
Focus: Conversion of a detached house in Horgen
Number: 1104.00
Discipline: Architecture, interior design
Typology: Residential
Service: 2 preliminary studies, 3 project planning, 4 execution, 5 realization
Year: 2022 - 2023
Costs: CHF 480,000
Location: Hernerholzgasse 37, 8810 Horgen, Canton Zurich
Clients: Private
The project
Initial situation: The timber-built detached house on Hernerholzgasse in Horgen is situated in a panoramic location with a view of Lake Zurich, next to railroad tracks and an agricultural zone.
Vision: The house is to be renovated step by step. The first interventions include energy-related measures and improve the standard of living. In terms of sustainability, the existing gas heating will be replaced with an air-water heat pump. While the granny apartment on the top floor will be left as it is for the time being, the focus in this step will be on the apartment on the first floor. Preparations are being made so that the upper apartment can one day follow with a renovation. Changing needs are thus taken into account.
Implementation: The apartment on the first floor will be fitted with underfloor heating, the surfaces renewed and the bathroom and kitchen replaced. The room layout will hardly be affected. The kitchen will be opened up to the living and dining room. The patio window will be enlarged towards the outside. Natural parquet flooring and muted natural colors create a cozy atmosphere. The color concept is repeated in the fitted kitchen and checkroom, the bathroom and the ceramic tiles. In the kitchen and bathroom, the fixtures are positioned in such a way that the room sizes can be optimally utilized.
By lightening the window frames and replacing the dark brown interior doors, the vibe from the 80s will give way to a new freshness.

P1017. International trade fair stand for Fouta
Raumtakt was commissioned to design and plan a sustainable trade fair stand for the young and innovative label Fouta, a brand of Meyer-Mayor AG. This celebrated its premiere at the "Neue Räume 17" event in November and was presented at the Ambiente textile trade fair in Frankfurt in 2018.
In the design, Raumtakt took into account the lightness of the Fouta textiles by using wooden elements from local forestry to create the atmosphere of a bathroom in which the Fouta towels come into their own. Elements such as the washbasin or the reproduction of shower rails intensified this effect.
A key criterion for the design was a space-saving concept, which was realized using modular, interlocking elements. In addition, the integration of discreet storage spaces for clothing, soaps as give-aways, brochures and staff catering was an important requirement.
Raumtakt designed a bar with kitchen stools as one of the main attractions of the trade fair stand, which served as an informal meeting point for customer discussions about the product.

The project
Raumtakt's task was to optimize the spatial concept of the building and to connect the rooms and facilities more effectively. The topic of better use of space was also of great importance for the conversion. As with other projects by Raumtakt Architekten, the aim was to retain the charm of the Italian vacation home despite the modernization. The conversion was also characterized by the peculiarities of a house that has existed for several centuries. The modernization of the kitchen and spiral staircase gives the house a modern character. The house looks modern and inviting thanks to the more generous use of space. The installation of a stove gives the kitchen and living room a homely atmosphere, making it family-friendly. To protect the walls from moisture, the walls were reinforced with an abrasion. The electronic installations throughout the house were also brought up to date.

Client: Private
The project
The country house in Gächlingen in north-eastern Switzerland dates back to the 19th century and has been sustainably renovated and modernized without covering up its historic and rustic core. To this end, Raumtakt carried out a wide range of renovation and refurbishment work in the house. The main focus of the architectural work was to adapt the house to today's living requirements. This project was reflected in the modernization of the room structures, which have now been adapted to create a modern and spacious living environment.
The kitchen on the upper floor was completely renovated to meet today's modern requirements. Despite the modernization, the original character of the house was retained, with a section of the natural stone wall, for example, being preserved. The kitchen leads directly into the spacious, light-flooded living room, which radiates a cozy atmosphere with its mullioned windows, wood panelling and tiled stove. The challenge when renovating the house was to combine the rustic wooden character with modern elements and thus create a contemporary character.
In the attic, renovation work was carried out on the sub-roof. After further repair work and a coat of paint, the façade shines in new splendor. Direct access to the garden from the basement was created, providing residents with more convenient access.
