Lateral conversion and mansard conversion over two commercial units

A lateral conversion across 25-26 Marylebone High St to form four new 2 bedroom flats. At fourth floor level at 25 Marylebone High St, a mansard roof extension was also added. The works were done whilst both commercial units were in occupation at ground and lower ground floor levels.

Part of the works also included improvements to the Topkapi restaurant with extended space into the old staircase to 26 Marylebone High St and a new shop front which was a significant improvement on the previous metal framed window.
