GS Renovation converts lofts throughout Fulham, working with the Victorian and Edwardian terraces that run from Bishops Park across to Fulham Broadway. In SW6 many neighbouring roofs are already converted, which helps the planning case and tells you a good deal about what works. We coordinate the professionals and build to their design.
Reading the roofscape in SW6
Walk a Fulham street and you can usually see what the council has accepted before. Where a terrace already carries a run of rear dormers or mansards, a matching design has a strong precedent behind it, and Hammersmith and Fulham Council will weigh consistency across the terrace when it assesses your application. Where a roof line is still unbroken, expect more scrutiny and a design that keeps the alteration off the street elevation entirely.
The stock itself favours two forms. A house with a rear closet wing suits an L-shaped dormer, roughly £55,000 to £80,000 on indicative London ranges for 2026. Where the roof is shallow or the terrace is mansarded already, a mansard gives the most volume at roughly £70,000 to £100,000 or more. We will walk the roof space with you and be plain about which one your house actually supports.
Consents and building regulations in Fulham
Conservation areas cover a good deal of SW6, and where they apply your permitted development rights for a loft conversion are removed, so Hammersmith and Fulham Council decides the design on its merits. Outside them, the usual terraced allowance of 40 cubic metres applies with the standard conditions, but no responsible contractor will tell you a specific house is permitted development without checking the designation and the property's planning history first.
Building regulations apply either way. A Fulham terrace converted into a third storey almost always needs a protected stairwell running to a final exit, fire doors and interlinked alarms under Part B, plus a stair meeting Part K on rise, going and headroom. The new floor is engineer-designed and carried on steels bearing into the party walls, which brings the Party Wall etc. Act 1996 into play and puts the duty to serve notice on you as the building owner.
