The fully-glazed System 3400 from Strähle was fitted in the offices on four floors of the consultancy firm. The design principle was transparency and reduction to the design minimum. The single-glazing and room-high all-glass doors impress with their elegant appearance and economy. The glass is held by variable floor and ceiling profiles made of black powder-coated aluminium. With no vertical posts, the variable System 3400 offers both transparency and versatility.
