GS Renovation converts lofts in Wembley, where HA9 combines interwar semis on the residential streets with a growing number of modern apartment blocks. The houses convert well, normally hip to gable with a rear dormer. The apartments generally cannot be converted at all. We coordinate the engineer and manage Brent Council building control.
Interwar semis around HA9
The Wembley semi was built with a hipped roof, and that hip is exactly where a staircase wants to arrive with standing height above it. Rebuilding the hip as a gable wall solves that, and a rear dormer behind the new gable squares off the back of the roof so the floor area becomes genuinely usable. In most HA9 semis the result is a double bedroom and a shower room, reached by a proper staircase off the existing landing.
Ridge height governs the design. We take the measurement from the top of the existing ceiling joists up to the underside of the ridge and want to see roughly 2.2m to 2.4m. Where a water tank still sits in the roof, taking it out and moving to a combi boiler or an unvented cylinder is a common enabling step, and it removes a leak risk sitting directly over your new bedroom.
Apartments, planning and building control
For a flat in one of Wembley's modern blocks, a loft conversion is not usually possible. The roof belongs to the freeholder, your lease does not extend into it, and the building's fire strategy and warranty are built around the layout as constructed. Consent, a lease variation and the managing agent's agreement would all be needed, and in practice they are not given. We will tell you that at the first visit.
For houses, semi-detached and detached properties carry the permitted development volume allowance commonly cited as 50 cubic metres, subject to matching materials, nothing forward of the roof plane facing the highway and obscure glazed side windows. Brent has conservation areas and Article 4 directions that remove those rights, so we check first. Building control then covers the engineer-designed floor, the protected stair route, fire doors, alarms and insulation.
