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

Kenton: the houses and the planning rules.
Kenton is Metroland between Harrow and Wembley: long avenues of 1930s semis with tiled bays, hipped roofs and gardens deep enough for a full-width extension. The houses were well built and most have never been extended beyond a small kitchen addition, so the potential is considerable.
The typical Kenton project is a rear extension for an open-plan kitchen and family room, a hip-to-gable loft with a rear dormer for two more bedrooms, and a refurbishment of the rest of the house to match. Because there are no conservation areas, most of it is permitted development.
There are no conservation areas in Kenton; most streets are unrestricted.
Harrow and Brent
The borough boundary runs through Kenton; we check which council applies at the first visit. Both allow most rear extensions and lofts under permitted development.
Hip-to-gable lofts
The 50 cubic metre allowance for semi-detached houses usually covers a hip-to-gable conversion with a rear dormer, confirmed by a lawful development certificate.
Larger extensions
Double-storey rear extensions and side extensions that come within a metre of the boundary need a householder application.

Loft Conversions in Kenton: your questions.
Is a loft conversion in Kenton 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 Harrow and London Borough of Brent.
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.
