The Rheinenergie AG is the largest power and water supplier in the Rhine Region. This administration complex is to replace an existing office complex from the 1960s that no longer meets the company’s ambitions for energy conservation and sustainable development.
HRA’s competition proposal from 2007 divides the brief into two blocks; the main administration centre and the ‘Mensa’, with facilities shared by all workers on the site. These are placed on either side of a new entrance garden on axis with the main site avenue. Both buildings in return respond to two scales; the lower free-form shapes are considered an extension of the tree canopy, while vertical orthogonal blocks align with the other built edifices on site.
