Many loft extensions fall under permitted development rights, subject to volume limits (typically 40 cubic metres for terraced houses and 50 cubic metres for detached and semi-detached houses) and restrictions on altering the roof's front slope. Larger extensions, those affecting the roofline significantly, or properties that are listed or in a conservation area usually need planning permission. Building regulations approval is always required, covering structural support, fire escape routes and insulation. We can confirm what applies to your Harborne property.
Yes, a well-designed loft extension typically adds one or more bedrooms, a bathroom, or a home office, and can significantly increase a property's usable floor area and value. The amount of usable space depends on your existing roof pitch and head height, which we assess during the site visit for your Harborne property.
Most loft extensions take around 6 to 10 weeks from start to finish, depending on the structural work required, staircase alterations, and the level of finish specified. We'll provide a realistic programme as part of your Harborne quote.
