my vision for the new Warsaw City Centre

project objectives

The primary design goal was to unify the currently separated buildings within Warsaw’s Central Business District and to incorporate the underused spaces above the cross-city line and nearby Defilad Square into a coherent urban center. This concept emerged from the scheduled rebuilding of the cross-city line tunnel and the subsequent absence of any public dialogue about the potential for integrating the new tunnel with prospective developments above it.

The existing spatial disarray in the city’s central regions, particularly around the Palace of Culture, extending to the Zawisza Square, could be effectively modernised. Hectares of neglected central urban space could be seamlessly integrated into the cityscape, transformed into appealing central developments, and become a hallmark of Warsaw for the 21st century.

Enhancing the central high-rise cluster, complementing the Wola cluster, could shape a remarkable city skyline and ensure a beneficial distribution of central urban functions between both high-rise zones.

The design concept is grounded in the core principles of the existing local development plan, incorporating some modifications to enhance the integration of the proposed development with both the new investments established in Warsaw over the past 30 years and those presently in various phases of the investment process.

Sketch visualizations are presented in the convention of a traditional wooden model, with subtle architectural modulation designed to showcase the potential diversity of building functions and to emphasize the tectonics of the proposed structures, providing contextual harmony with the existing urban fabric.

The proposed concept has been developed without a detailed analysis of ownership, engineering, sunlight exposure, shading, or input from building consultants.

Proposed amendments to current masterplan (MPZP) for the Defilad Square area

continuous and consistent street wall and street section along Jerozolimskie Avenue, from Zawisza Square to Dmowski Roundabout, in line with the city council’s vision outlined in recent years

adjustments to the proposed pedestrian link between Warsaw Central Metro Station and Central Railway Station, simplification of the geometry to allow for vista termination by Central Railway Station and Varso Tower in the backdrop

division of the 18U/UA single tower into two smaller high-rise buildings to achieve better urban integration, scale, and massing

lowered height and reduced footprint of proposed high-rise building 11.U/MW

additional landmark high-rise at intersection of Jerozolimskie Avenue and Emilii Plater Street to enhance integrity, massing, and scale of Warsaw’s central cluster, complementing the recently constructed and planned buildings

proposed additional mid-rise building on 10.U/UK parcel to improve height transition between low rise structures in the north-eastern part of the Defilad Square and high-rise landmark towers along Emilii Plater Street

proposed tree-lined streets where feasible
