The project introduces several public and semi-public spaces and creates various opportunities for informal communication, as well as zones for play and sports for children. They create a variety of passage options and underline the importance of the complex as an entrance to the newly created urban area.

The building volumes respond to the irregular shape of the site. A system of parallel and perpendicular lines to the surroundings shapes the walking lines, visual and spatial connections and forms the characteristic pentagonal floor plan of the four buildings. The individual sculptural volumes thus fit into their surroundings and respond to their scale and functionality. The high residential tower in the southeast part characterises the entire complex with its character and memorable silhouette and becomes an urban landmark at the entrance to the new quarter. The central location of the mail hall of the Union of Architects in Bulgaria, reinforced by its sculptural presence, underlines the importance of this public function in the project. The colour accent of the ground floor highlights it as a primarily public area, and the colonnades increase the architectural value and create a series of different passage and recreation areas.
