Paul Cashin Architects appointed architects for new build house in Brighton, East Sussex

Paul Cashin Architects are pleased to have been appointed architects for a contemporary new build house in Brighton, East Sussex.

The existing house is positioned along a coastal site beholding incredible views out to the English Channel. The brief sets out a scheme to alter the existing house and design a modern new build property to be sited adjacently on the generous plot.

First impressions of the location bring forward design considerations of the exposed, saline environment, thin and narrow site proportion, roof height limitations and proximity to neighbouring properties as well as the relationship with the existing house.
