Constructed between 1863-1877, this Grade II listed six storey terraced building is located in Cornwall Gardens, South Kensington includes a basement and mansard. The brief awarded to ByrneLooby London was to divide the property into six high specification flats with lift access. The aim of the scheme was to develop the property to it's highest potential in terms of floor space and finish quality to enhance the revenue of the property.
The scope of works included replacing the existing shallow mansard with a new steel framed mansard creating a large open plan fifth floor space with access via a large electronic rooflight to a roof terrace over. The existing reinforced concrete staircase between ground and first was refigured to accommodate additional space under. A new lift shaft was designed to be independent from the floor structure to minimise vibration issues. New open plan spaces throughout the property required detailed design most notably within the basement under a traditional brick arched entranceway. Repairs including the levelling of floors, improvement of timber joist bearings, provision of noggins and some general brickwork repairs.
