GS Renovation builds loft conversions in Wanstead, on the period houses lining the streets between Wanstead Park and Epping Forest in E11. These are visible, well-kept roofscapes, so how a dormer is designed and detailed matters as much as how it is built. We coordinate the engineer and take Redbridge Council building control through to certificate.
Designing a dormer that suits an E11 house
A dormer that is set back from the eaves, held below the ridge line and clad in a material sympathetic to the house will get through planning and look right in twenty years. One that runs the full width and full height of the rear slope in white plastic will do neither. On Wanstead's period houses we detail cheeks in tile hanging, slate or lead-effect finishes, keep the window proportions in line with those below, and set the roof back rather than pushing to every edge.
That approach also suits the conservation areas around Wanstead, where permitted development rights for loft conversions are removed and a planning application to Redbridge Council is required. Outside them, the commonly cited allowance is 40 cubic metres of added volume for a terrace and 50 for a semi or detached house, subject to matching materials, obscure glazed side windows, no balconies and nothing built forward of the existing roof plane.
Structure, stairs and sign-off
Ridge height governs whether the room works at all, so we measure roughly 2.2m to 2.4m from the top of the existing ceiling joists before anything else. The new floor is then built on joists sized by the structural engineer and carried on steel beams that span to the party walls and bear on padstones. The original ceiling joists are left carrying the ceiling only, which is all they were ever designed to do.
The stair has to satisfy Part K on rise, going and headroom, and a space-saver stair with alternating treads is only acceptable where it serves a single room, which rules it out if you want a bedroom and a separate en suite. Part B requires a protected stair route to a final exit with fire doors and interlinked alarms. Redbridge building control inspects each of these stages, and party wall notices are served by you as building owner.
