The original structure contained a cavernous space into which the architects inserted an independent load-bearing structure that supports two additional levels to create the floor space required by the client. “We didn’t want to build a typical facade indicating an office building,” explained Cleef, “so we wrapped a consistent pattern around the building that doesn’t reveal what is happening inside.”
A lobby on the ground floor leads to a staircase housed in an angular volume that projects from one of the end walls. The holes merge with larger openings to form entrances with irregular edges that continue the pattern of the facade. This was assembled on site in just two weeks and envelopes an insulating layer of glazing and aluminium sheet cladding.

German architecture office Wurm + Wurm has transformed a derelict industrial building into offices, featuring a concrete facade punctuated by rows of hexagonal openings (+ slideshow). “The decision to retain as much of the old structure as possible is the decision to keep a piece of industrial history from the former GDR alive,” architect Sebastian Cleef told Dezeen. “Therefore the old structure of columns and roof trusses can still be seen inside the building.”
A reinforced concrete elevator shaft and a masonry structure that accommodates the building’s sanitary facilities help to prop up the new roof, while a framework of columns and beams supports the extra storeys “like a table”. One corner of the top floor is set back to create space for a balcony that looks out towards the surrounding countryside through the apertures in the facade.
