Dormer, mansard and rooflight options scoped for structure, stairs, weatherproofing and planning path.

Read this Borough loft conversion brief against “Borough context”. Borough Market — London's oldest food market, trading since the 13th century beneath the railway arches — defines the area's character and draws a million visitors monthly. Southwark Cathedral anchors the historic core near London Bridge. The written scope still follows photographs of the unit.
