One Coleman Street is a new 235,000 sq ft office building for Legal and General in the City of London completed in 2007. The scheme set out to unite the disparate urban context of the eastern end of London Wall and Coleman Street by re-establishing its street wall, and through the creation of a new garden on the southern side. The fa£ade utilises polished pre-cast concrete cladding panels configured in a geometric arrangement expressed through a series of interlocking and alternating triangulated surfaces. The fenestration is set at an angle, creating a robustly modelled surface running around the curvature of the building. The directional geometry with alternate floors arranged in the opposite direction is resolved by the triangulation of the spandrel.
