 Built as a detached structure formed from three separate blocks, the first, main, block forms the core of the store itself, with the main façade of the building fronting Aleje Jerozolimskie, the second construction operates as a food hall, whilst the third became a small office building attached to the rear of the main store via the restaurant section at ground floor.The main store was previously famous for its high-modernist windows, which were constructed using Polish oak frames and glass panes with an anti-reflective coating - a first for post-war era Polish architecture.The south elevation's main façade was specially designed to carry advertising and for most of its history was adorned with the store's trademark neon lights, arranged in the shape of spirals and supplemented with the vertically stacked letters "CDT", which stood for the store's original name 'Centralny Dom Towarowy' "Central Department Store".
