Loft Conversions in Barnes.
A loft conversion adds a bedroom and bathroom without touching the garden, and in most of Barnes 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.

Barnes: the houses and the planning rules.
Barnes is a riverside village inside a loop of the Thames: Georgian houses on the Terrace, the Green with its pond, Victorian streets running back towards the Common, and the wide Castelnau estate leading to Hammersmith Bridge. It is quiet, well kept and closely protected.
The projects match the houses: refurbishments of Victorian family homes, side-return and rear extensions, lofts, and the occasional basement where the ground conditions near the river allow. Richmond's conservation guidance applies almost everywhere, and flood risk is checked on riverside sites.
The Barnes Green, Castelnau and Barnes Common conservation areas cover most of the village.
London Borough of Richmond upon Thames
Richmond decides applications; Article 4 directions in the Barnes conservation areas mean most external changes need a full application.
River and flood risk
Riverside streets sit in the Environment Agency flood zone, which affects basements and requires a flood risk assessment.
Castelnau
The paired villas of the Castelnau estate have specific guidance on roofs, side extensions and boundary walls.
