Unified under a single ‘floating’ roof plane, this scheme for two glass sunrooms on top of an Art Deco apartment block in Poole, Dorset, seek to create simple, contemplative spaces, exploiting the surrounding far-reaching views of the Dorset coastline.This subservient, steel-frame addition perches lightly over the existing concrete structure and is designed to subtly reflect its Art Deco context in a sympathetic and minimalist manner.The new pavilion and external areas have proved a real success, with all users now enjoying the new found lease of life for their rooftop.
