6 bed terraced house

This property is a self-contained office building on Hallam Street in Marylebone, Central London, with approximately 5,615 sq ft of floor space. The building has a mix of open-plan and private spaces, good natural light, and retained period features from its Edwardian origins in 1903. The property benefits from planning permission for conversion into a substantial single private residence, which would include six bedrooms, seven reception areas, a lift, and a potential rear mansard extension adding an additional 45 sq m of space.
