TwentyFive/OneThreeSix occupies an island site and will provide both 44,520 sq ft of light-filled Grade A office space along with 23 apartments and two penthouses within The Portman Estate in Marylebone. While housed in the same building, designed by award-winning architectural practice Stiff and Trevillion, the two elements of the mixed use building have separate access and individual identity and character.
The workspaces, set over six floors, are designed with quality, productivity, sustainability and wellbeing at their core. The eye-catching exterior combines a palette of limestone brick and terracotta with large scale glazing to ensure that natural light floods into the office floors. Thoughtfully designed by Stiff+Trevillion and interior architects MSMR, the distinctive residences showcase lateral living in central London. Most of the residences will have Juliet balconies or terraces and access to excellent amenities including a fully equipped gym, secure basement parking, extensive storage facilities, concierge and 24-hour security.
