Why use a local architect in Portsmouth?
Britain's most densely populated city outside London, Portsmouth is street after street of Victorian and Edwardian terraces in Southsea, Fratton and North End, with interwar and post-war housing on the mainland and new waterside flats at Gunwharf. With conservation areas in Old Portsmouth and Southsea, a designer who has taken projects through Portsmouth City Council planning before is worth the conversation.
