CreaTower I office high-rise with CreaTower II urban planning concept

In the Tech Cluster Zug, the 40-metre office high-rise Crea I and the 60-metre residential tower Crea II, the latter with a large base, will be built in two stages. Together with the sculpture Semiramis (Gramazio Kohler Research, ETH Zurich), they form a harmonious ensemble and a central square.

The ten-storey office building will serve as the headquarters of VZ Depotbank and is accessed via an arcade facing the public V-Platz. The new building has an almost square column grid with a slightly off-centre two-part core. The bays along the façades contain the workplaces in various arrangements, the meeting rooms and the recessed, two-storey terraces. The four interior bays adjacent to the core offer space for exchange and informal meetings, with spiralling double-storey rooms and open flights of helical stairs. It is this central void, with horizontal and vertical views and varying headroom, which connects the floors into a continuous, inspiring work landscape. The sequence of these diverse spaces creates a generous atmosphere, but also with scale and intimacy for the users. The terraces feature intensive planting and are arranged in staggered pairs that spatially connect three storeys.

The load bearing construction with the vault-column structure above two basement levels is 33% lighter and has 35% fewer CO2 emissions than a conventional construction. Here, the vault-column structure makes a significant contribution to sustainability with 66% less mass and 69% fewer CO2 emissions when compared to usual concrete slabs.
