About the project

Trillium is a landmark residential development in Paddington Green in the City of Westminster, moments from Marylebone, Mayfair and Edgware Road station. Developed by Berkeley and designed by Squire & Partners, the scheme rises across three towers, its tallest reaching 39 storeys and 166 metres to become the tallest building in Westminster, with an exterior inspired by London's traditional red-brick mansion blocks. Interiors by BradyWilliams favour a calm, neutral palette with natural, earthy textures across Manhattan, one-, two- and three-bedroom apartments and penthouses. Residents enjoy over an acre of landscaped green space plus a swimming pool, hydrotherapy and ice-plunge pools, saunas, a fitness studio, private dining, co-working spaces and 24-hour concierge.
