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.

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.
