Stock Photo - Netherlands Embassy, Berlin. Exterior nightshot across River Spree with Alexanderplatz Fernsehturm, TV tower in background. Architect: Rem Koolhaas OMA. In order to activate the entire volume of the embassy, one continuous promenade, the trajectory, meanders through the eight level building. It is a singular spatial element excavated out of a cube of generic office floors and workspaces. From the street_level entry to the roof terrace the trajectory links the collective ´public´ spaces of the embassy by means of ramps and stairs. The large roof garden terminates this continuous spiralling route through the structure. Th embassy is a ductless building, all services are integrated into th earchitecture. The pressurised trajectory acts as a duct. fresh air migrates into the offices through openings in the structural walls and into negatively pressured facade plenum.
