Loft Conversions in Hammersmith.
A loft conversion adds a bedroom and bathroom without touching the garden, and in most of Hammersmith it is the most cost-effective way to gain a floor. Which type suits your house depends on the roof: Victorian and Edwardian terraces usually take a rear dormer, 1930s semis with hipped roofs need a hip-to-gable conversion to make the space usable, and in conservation areas a mansard or rooflight scheme may be the only option.
We start by measuring the roof. About 2.2 metres from the top of the joists to the ridge is needed for a comfortable room; we check this at the first visit before anything is drawn. From there our architects design the layout and the stair, our engineers design the new floor and any steelwork, and our team builds it with the house occupied throughout.
Most lofts are permitted development within the 40 or 50 cubic metre allowance, with the dormer at the rear. Flats, listed buildings and streets with Article 4 directions need a planning application, and every loft needs building regulations approval for the structure, fire escape and insulation. We manage all of it.

Hammersmith: the houses and the planning rules.
Away from the Broadway, Hammersmith is a district of tight Victorian terraces: Brackenbury Village's two-storey cottages, the larger houses around Ravenscourt Park, and the Georgian and Victorian houses along the river at the Mall. The terraces are narrow, the gardens are short and the demand for space is constant.
Side-return extensions are the signature project here, opening the ground floor into one kitchen and living space, often with a loft conversion in the same programme. The conservation areas ask for extensions that sit below the neighbours' sightlines and use matching brick.
The Brackenbury Village, Ravenscourt and Starch Green, and Hammersmith Mall conservation areas cover much of the residential district.
London Borough of Hammersmith and Fulham
The borough decides applications and applies Article 4 directions in Brackenbury Village and other conservation areas, removing permitted development for rear and roof extensions.
Side returns
The council's guidance favours side-return extensions kept low with rooflights; full-width rear extensions are assessed against neighbours' amenity.
Basements
The borough's basement policy applies, with a construction method statement and limits on depth and garden coverage.

Is a loft conversion in Hammersmith permitted development?
Often, provided the added volume is within 40 cubic metres for a terrace or 50 for other houses and the dormer is at the rear. Flats, listed buildings and streets with Article 4 directions need an application to the London Borough of Hammersmith and Fulham.
How much headroom do I need for a loft conversion?
About 2.2 metres from the top of the ceiling joists to the ridge. Victorian and Edwardian roofs usually have it; 1930s hipped roofs often need a hip-to-gable conversion to make the space usable. We measure at the first visit.
