The three buildings that make up Bauman Lyons Architects'The Terrace are distinguished by their external facing material. The building that faces Grantham Street is the only one clad in slate. This steel-framed, four-storey building has hollow-core concrete plank floors with structural screed topping and a pitched slate roof. On the south facade, above a ground floor of blockwork, the walls are of steel studwork lined on the outside with insulation, impermeable breather membrane and a rainscreen of 40mm thick rectangular slate panels. The slate is detailed to read as an extension of the roof plane; this is emphasised by the use of narrow vertical joints and wide 50mm horizontal joints between panels. To reinforce the horizontal nature of this facade, balconies are recessed behind the rainscreen and their slate-clad balustrades act as an extension, of it.
