Given the close neighbouring buildings, the only possible option was an additional floor. Local legislation is not allowed to change the facade of the building, with the exception of the trim and Windows, as this area is a historical part of the city, and the authorities seek to preserve it in its original form.

The back yard was involved in the project fully. A relaxation area and a garden not only decorate the residence, but significantly expand it.
