TwentyFive is the prime residential element of a mixed-used redevelopment at the former Regent House building on Edgware Road. It was a joint venture between Native Land and The Portman Estate. Planning consent was granted in 2016 for a mixed-use development comprising prime residential apartments; Grade A office space; and retail units which will house high-end curated shops and eateries selected by The Portman Estate. The development occupies a single building on an island site in Marylebone, with the cladding design a combination of limestone, brick and terracotta materials sympathetic to the architecture of the surrounding early 20th Century mansion blocks.
