This project on Alexanderplatz combines two independent but related buildings: a plinth that corresponds to the neighbouring buildings in terms of volume, materiality and façade structure, and a high-rise that responds to the existing and planned development along Alexanderstrasse.

The three floors at the base of the plinth contain retail spaces, restaurants and co-working areas, while the upper section is dedicated to residential use. Airy, textile sun blinds are positioned in front of the generous glazed areas, adding a summery lightness to the building. A ‘Garden Club’ on the 8th floor invites the occupants of the tower block to spend time together. In the courtyard of the plinth building, residents can access an additional spacious roof garden.

The tower is primarily used for offices. A vertical joint divides the overall volume visually making the building appear to consist of two elegantly proportioned towers. The façade will include areas for photovoltaic units, giving the building the potential to cover part of its own electricity requirements in the future. A box window construction will allow natural ventilation of the tower block. The concept for energy saving and CO2 reduction also includes the use of geothermal energy and grey water heat.

In this building, the combination of living, working and retail as a traditional typology of the European city is revisited and reinterpreted in an innovative way. In this way, Alexanderplatz is strengthened as a metropolitan centre of the city. The building's iconic character reflects the significance of the site in recent history. While the active façade points towards the future.
