GS Renovation converts lofts across Palmers Green, in the Edwardian terraces and semis lining the streets between Southgate and Edmonton. In N13 a rear dormer suits the terraces and hip to gable suits the hipped semis, and the two are often combined. We coordinate the structural engineer and complete the work under Enfield Council building control.
Two housing types, two conversions, in N13
Palmers Green splits neatly. The Edwardian terraces with a rear closet wing take a rear dormer, or an L-shaped dormer wrapping over the back addition where the wing is deep enough to be worth the extra cost. The semis with a hipped side roof want that hip squared up to a gable first, with a rear dormer behind it, because the hip is what removes the usable width from the middle of the new room.
Both start from the same measurement. Roughly 2.2m to 2.4m from the ceiling joists to the ridge is what a conversion needs before you start considering lowering ceilings below or lifting the roof, and Edwardian roofs in N13 are generally generous enough. The purlins and any chimney stack passing through the space then set the practical limits on where the stair, the bathroom and the wardrobes can go, so we survey those together.
Fire safety and Enfield Council approvals
Going to a third storey changes the fire strategy completely. Part B normally requires the stairs to form a protected route from the new loft all the way to a final exit, which means fire doors to the rooms opening off it, sound construction to the enclosure and interlinked alarms on every level. In practice this often means replacing doors on the first floor landing too, and it is one of the costs people miss when comparing quotations that leave it out.
On planning, the allowances are 40 cubic metres for a terrace and 50 for a semi or detached house, subject to matching materials, no projection forward of the existing roof plane, no balconies and obscure glazing to side windows. Enfield Council conservation areas remove those rights, so we check your street rather than assume. Steels bearing into the shared party wall make the job notifiable, and you serve notice as building owner with our detail behind it. Building control then inspects the steelwork, the new floor structure, the stair and the insulation before sign-off.
