Loft Conversions and Extensions in Canary Wharf

The Victorian terraces in Cubitt Town and Millwall, on streets like Manchester Road, East Ferry Road, and Glengall Grove, typically have enough ridge height and roof pitch for a rear dormer. A dormer is a box-shaped structure that extends vertically from the slope of the roof, creating full-height walls and more usable floor space than a pitched ceiling allows. Ridge height, the highest point of your roof, needs measuring before design begins, because it determines whether you will have adequate ceiling clearance for a habitable room once insulation, flooring, and structural beam work are accounted for. Post-war homes in the area can have lower ridge heights than Victorian stock, making this check particularly important. For end-of-terrace homes, an L-shaped dormer, extending across the rear slope and the back addition, gives a larger floor plan. A rooflight conversion, which adds windows to the existing slope without changing its profile, suits smaller budgets but limits the usable floor area to the existing loft footprint. A mansard can be considered on the right property with appropriate planning advice. See our loft conversion cost guide for a breakdown by type.
