A mews townhouse in a conservation area, SW3, was updated and extended to provide a new ‘mansard’ style loft conversion with the existing vacant basement converted in to an additional family room space.
Rather than adding a ‘pastiche’ extension the planners were in acceptance that the loft extensions would be better suited for a modern extension, and thus external zinc roofing and cedar cladding was to be permitted. However, being in a conservation area the principal facade must remain un-touched.
To drive natural light in to the converted basement a central light-well was installed from ground to second floor with a glass ceiling to the basement area and formed roof resulting in natural light flooding throughout the entire dwelling.
The loft conversion offered a master bedroom suite with an opulent bathroom and dressing area which spread across the 3000 sq. ft. mews terrace.
The redundant basement became a much needed addition to the property and increased the floor space internally by 500 sq. ft, and importantly the conversions could not be seen from the main facade.
The conversion almost became ‘bunker-like’ in its approach given that access in to the back garden was not a possibility due to its size and proximity with 5 other neighbouring properties, and thus natural light became reliant upon the internal light-well and strengthened glazing slabs.
The project was completed in 6 months at the cost of £375,000 via selective contractor tendering.
