The main entrance is centrally positioned on the northern side of the building, while the interior spaces are organized vertically from the entrance level to the second floor around a newly designed staircase.
The primary design concept was to establish the strongest possible connection between the interior and exterior spaces while simultaneously preserving the occupants’ privacy. Consequently, the main living areas, intended for longer periods of occupancy, are oriented towards the courtyard to the west, while the openings on the eastern, street-facing façade retain their existing dimensions, maintaining continuity with the surrounding streetscape.
