This new administration office and welfare facility at the vast BMW car plant in Leipzig is a huge, uninterrupted, column-free space containing open-plan offices, with a dramatic roof set 6.5m above the floor and supported on inclined legs at the perimeter. The roof is a 2mdeep space frame of twin 420 x 8mm steel plates, designed to resemble long extruded ribbons of steel, and relatively lighter secondary members.
AHA has worked with architect Barber Casanova Ruffles on this wastewater treatment facility at Lowestoft. The enclosure building blends into the low-lying coastal terrain. It is elliptical on plan - about 160m long and 113m wide - and is covered with a double-curving roof which 'floats'on glazed walls. A metal diaphragm deck spans between curved rib-like steel trusses, supported at the perimeter on elastomeric bearings on CHS columns that cantilever from the 7m-high perimeter retaining wall.
