Renovation of residential house in Ljubljana

The renovation of the house retained its exterior dimensions of the square floor plan and the height, taking advantage of the previously empty attic volume. The attic was given a new roof design, daylit with roof windows. Because of the desire for more light on the first and ground floor, the façade windows have been increased. A large picture window was installed on the back garden side. The comprehensive renovation included an energy retrofit and renovation of all installations.

House is located in Ljubljana.
