FLORENC 21: Block B06

The proposed office building in the very heart of Prague is becoming a key part of the transformation of Florenc into a lively urban district – a place where work, meeting and relaxation naturally intertwine.
For centuries, Florenc was a place where different layers of the city, people, stories and architectural styles met. The B06 office building builds on this multi-layered character with the concept of “Many faces, one identity”. The building's single function is wrapped in a varied façade layer which, like a strip of film, changes from frame to frame. It responds to the character of the place, its historical development and the fine human scale of the traditional Prague city block. The result is a building whose architecture reflects the diversity, complexity and vibrancy of the place in which it stands.

A Contemporary Dialogue with History and Context
The design draws on the character of traditional Prague perimeter-block development, but does not adopt its principles literally. Instead of historicising forms, it works with their contemporary interpretation – with the rhythm of the façades, vertical articulation, the treatment of the corner and an emphasis on human scale. Thanks to a regular grid and the variability of the individual façades, the large volume of the building visually breaks down into smaller parts that relate better to the varied character of the surrounding buildings.
The expression of each façade is further shaped by its orientation to the cardinal points. The system of shading elements is not merely a technical solution but becomes part of the building's architectural vocabulary. While the south, east and west façades gain greater plasticity and depth thanks to the louvres, the north façade retains a calmer and more compact character. The building thus responds to its surroundings not only formally but also functionally.






The Building's Colour Palette
The colour scheme of the building takes its inspiration from Prague's roofscape. Shades of white, grey, copper green and terracotta red refer to materials and colours naturally present in the city and help the individual parts of the building acquire their own identity.






A Lively Street
The ground floor of the building is designed to be a natural part of life in the new district. Restaurants, shops and services at street level create an active interface between the building and the street and bring life to the public space throughout the day.
We see the space between the building and the Negrelli Viaduct as a place of exceptional potential. The combination of an active ground floor, outdoor seating and intensive pedestrian movement creates the conditions for a lively urban environment where people will not only pass through but also stop, meet and spend time. It is precisely such places that give a city its atmosphere and become a natural part of everyday life.












Green Oases of Calm
Greenery is designed as an integral part of the architecture, creating a system of interconnected landscapes, each with a distinct character. The roofscape draws inspiration from the open Czech countryside, with grasses, pines and stone elements reminiscent of rock outcrops. In contrast, the northern atria work with shade, moisture-loving vegetation and a more intimate atmosphere that contrasts with the openness of the roof. Smaller terraces on the upper floors form a transition between these two worlds, complemented by trees, seating nooks and views of the Prague skyline.
The individual layers of greenery are thus not created as isolated elements but as part of a single landscape concept that gives the building its own identity and brings a diverse natural environment into the densely built-up city centre.
