Mennica Legacy Tower

Warsaw, Poland

The Mennica Legacy Tower development is located in the Central Business District of Warsaw. The program is divided into a 35-story tower located on the southeast side of the site and a smaller 10-story building on the west side of the site. It is part of a newly approved master plan that governs development in this area. The project is approximately 100,000 square meters, with 80,000 square meters of Class A office space, including a conference and a fitness center as well as ground-level retail. Four levels of underground parking and ancillary services encompass the remaining 26,000 square meters. Between the two structures is a large open plaza that provides ample space for outdoor seating and a variety of landscape features.

The 2,000-square-meter tower floor plate provides an almost column-free space with 11- to 13-meter lease spans and a 1.35-meter planning grid. The tower mass has rounded corners on the northeast and southwest sides that reduce the visible length of the east and west facades; on the opposite corners, the tower features a strong vertical edge. The southeast and northwest corners are further highlighted by slightly recessed vertical slots that break up the building’s mass and introduce a dominant, recognizable feature that will make the building an urban landmark. The textured, saw-toothed facades reinforce the rounded corners and give the enclosure an ever-changing appearance as one moves around the building.

The southeast corner of the tower steps in three-floor increments outward as it rises, which opens up the slot to the sky and creates a dynamic and unique profile that will be a glowing building feature at night. A sloping screen wall at the building’s top further highlights the profile and emphasizes its highest point on the southeast corner.

The taller building will have a three-story lobby with a cable-supported enclosure, utilizing a low-iron glass with a non-reflective coating that blurs the boundary between interior and exterior space. The tower core is clad with large stone slabs that accentuate the solid mass of the core, in contrast to the lightness of the building’s lobby.
