One Braham is a new 18-storey commercial office building targeting tenants in the burgeoning technology, media and telecoms market, as part of the wider Aldgate masterplan. The scheme provides 309,000 sq ft of office space and 10,000 sq ft of retail at ground level, reflecting current tenant driven demands for flexibility and efficiency by adding 30 per cent more area to a previously consented scheme on the same site. The sustainability strategy focuses on an energy efficient building envelope and services design to target a BREEAM Excellent rating. Floorplates consist of exposed composite concrete soffits for thermal mass, curtain walling provides an abundance of natural light with brise- soleil controlling solar gain.
