The post-war modernist tenement house located at 6/8 Św. Barbary Street in Warsaw has been renovated and adapted according to a design by Grupa 5 Architekci. The building underwent a comprehensive renovation, restoring its functionality while meeting the requirements of apartments intended for rent. The primary design goal was to create an attractive, orderly space with a scale friendly to future users. Despite its location in the very center of Warsaw, every apartment features a balcony with a view of the greenery in the square by St. Barbara’s Church and a quiet courtyard.
The corner tenement was erected at the turn of the 1950s and 1960s as part of a modernist ensemble realized within the expansion of the Long-distance Telephone and Telegraph building on Nowogrodzka Street. The facility stands as a testament to the best patterns of Polish post-war modernism, constituting a significant fragment of Warsaw's architectural heritage.
The volume of the Telephone and Telegraph building, completed in 1933 and recognized as one of the most important modernist structures in Poland, set the urban and stylistic direction for the tenement on the Św. Barbary Street side. Constructed in the spirit of the era, the building features a restrained and rhythmic façade design. From the courtyard side, it took the form of a gallery-access building—characteristic of modernist residential projects that combined aesthetics with functionality.
The interiors of the adapted tenement refer to the restrained forms of post-war modernism. They are filled with bright materials: terrazzo, concrete, steel, and glass. Their juxtaposition with natural wood, introduced during the renovation, warms the renovated space of the building.
