In Küsnacht, a heritage-protected single-family house is being transformed into a spacious villa with lake views. Because the existing building could not be torn down, the challenge was to get the maximum out of the protected building – and correctly position it as a luxury property with a narrow buyer pool. smzh manages the central interfaces of property access, feasibility, permitting and sale.

Blue marks a value jump.
This single-family home is heritage-protected and could not be torn down. The challenge was to preserve the protected substance and develop it into a spacious villa with lake views. At the same time, the buyer pool for such a property is narrow – positioning, fit-out and sale therefore had to be considered as one from the start.



Heritage protection, location and substance set the frame. What mattered was which potential is achievable within these limits.
The existing single-family home is being renovated in keeping with heritage requirements, extended and repositioned as a spacious villa with lake views.
For high-quality individual properties, the buyer pool is small. Positioning, fit-out and sale must therefore be aligned early to focus on the right buyers.
