Cornerstone is an iconic HQ office in the Stockport Town Hall Conservation Area. Externally, the 54,000 sq ft office responds sensitively to its civic setting creating a seamless transition between the Town Hall and neighbouring residential apartments. The facade is constructed from pre-cast concrete panels which, along with features such as the cloistered walkway, appropriately address the civic location. Internally, the building delivers cutting edge customer services together with smarter ways of working for tenant Stockport Homes. The building achieved an EPC A Rating, with features including high performance glass and concrete cladding to create thermal mass.
