The transformation of a 1970s office into residential apartments. The design included the transformation of open plan office floors into flats (4 per floor). Existing patent glazing was replaced with an expressive brick façade. The design reinterpreted the rhythm and proportions of a neighbouring grade 2 listed building. Three brick types were used to mediate between the colours and materials of the historic building and the office block. Organic patterns balance the formal composition of the façade with a sense of playfulness. We worked collaboratively with the conservation officer to agree design principles before developing the final proposals.
