Administration building UVEK, Ittigen
best architects 22
The administrative centre of the federal
authorities in Ittigen accommodates the departments of Environment, Traffic and
Transport, Energy and Communication (UVEK) of the Swiss Confederation. In an
open competition for a two-stage expansion by 900 workstations, the jury chose
the proposal by Berrel Kräutler Architekten. The existing complex is being
extended with a pair of elongated buildings aligned parallel to one another. A
vibrant campus with rhythmically staggered open areas and pathways is emerging.
The first building was completed in 2020. In plan and section, the new
seven-storey building is clearly structured. Arranged
around a massive central concrete core are circumferential floors consisting of
a composite timber and concrete construction. Found at the building’s heart is
an astonishing spatial sculpture, an atrium framed by two curving staircases.
This enthralling interior, with its varied views, reflects a spirit of exchange
and community. The open-plan offices are strung along the façade and are
distinguished by a warm atmosphere, wonderful views as well as optimal lighting
and ventilation. Vertical timber lamellas and projecting circumferential strips
characterise the façade and integrate the building into the existing campus. With
their great variety of landscape elements, the green outdoor areas offer space
for rest and recreation.
