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

Chiswick: the houses and the planning rules.
Chiswick is Victorian and Edwardian west London at its most complete: the terraces of the Glebe Estate, Bedford Park, the first garden suburb, with its Norman Shaw houses, and the riverside at Strand-on-the-Green. Much of it is in conservation areas administered by Hounslow, with Bedford Park among the most closely protected.
Our Chiswick bathroom, with large-format porcelain, a wall-hung vanity and a walk-in shower, is typical of the work here: careful upgrades inside period houses that keep their character while bringing services up to date.
The Bedford Park, Strand-on-the-Green, Chiswick House and Old Chiswick conservation areas cover much of the district.
London Borough of Hounslow
Hounslow decides applications. Bedford Park and the other conservation areas carry Article 4 directions, so most external changes need a planning application.
Side returns
The Victorian terraces off Chiswick High Road are ideal for side-return extensions; outside conservation areas these often fall under permitted development.
Riverside
Properties near the Thames may need flood risk assessments for basements and ground-floor changes.

Loft Conversions in Chiswick: your questions.
Is a loft conversion in Chiswick 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 Hounslow.
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.
