Stucco terraces, mews and mansion blocks
Belgravia and Pimlico are stucco-fronted terraces with small, deeply enclosed rear gardens and, more often, flat roofs and rear extensions that have become the real outdoor space. Marylebone and Bayswater add mansion blocks where the outdoor room is a balcony or a shared roof. The mews houses behind the main terraces have compact paved courtyards. St John's Wood and Maida Vale are the exception, with genuine gardens behind larger villas. In most of the borough the question is not what to plant but what the structure can carry and how anything gets up there.
