This block, which forms the boundary of the new Florenc21 development, will serve as a sort of gateway from the historic part of Prague to the newly emerging neighborhood. It is bounded by Na Florenci and Křižíkova streets, situated at an imaginary point where the historic and modern parts of the city converge—a fact further emphasized by the nearby elegant Desfourský Palace, the City of Prague Museum, and Masaryčka, designed by Zaha Hadid’s studio. This area is crossed by an elevated section of the north-south Magistrála highway, which complicates the overall situation and also serves as a prominent feature.

Block B01 is intended to be a dynamic office building with retail spaces on the ground floor that will extend all the way under the highway. On the northeast side, this block will be directly connected to the Florenc transit hub, which will facilitate the movement of people. The corner building, facing the Desfourský Palace and the Masaryčka building designed by Zaha Hadid’s studio, is conceived as a local landmark that underscores its role as a gateway.

A total of 156 teams entered the architectural design competition for Block B01; 8 advanced to the next round and 4 teams to the finals. The jury selected the design by TEAM 111 – ADEPT | ohboi as the winner, as it sensitively responds to the surrounding urban fabric. This solution harmoniously combines building volumes, distinctive facades, and green rooftop terraces.

Our vision is to create a unified urban complex where the Bastion building, two new buildings, and the space beneath the elevated highway merge into a single entity. The active public ground floor connects these elements, while a continuous pedestrian network intersects the individual volumes and passes between them, thereby becoming the spatial backbone of the design. Here, the rhythm of the city meets the structure of the architecture.

It is an open grouping where programs overlap and support one another—from commerce to community, from work to recreation—and together create a cohesive and generous identity. Informal cultural programs and everyday social activities are situated side by side with more formal functions along the street frontage and in the offices, creating a multi-layered experience for both users and visitors.

Vertically, the project is structured into three layers: an open and permeable ground floor with public functions, flexible and efficient workspaces in the middle, and shared rooftops with gardens, community spaces, and views of the city. This layering creates a new form of vertical urbanity and supports diverse uses throughout the day.
