How we approach smoke vent rooflights (AOVs) in Muswell Hill
For Muswell Hill homes and buildings we offer smoke vent rooflights (AOVs): automatic smoke ventilators at the head of stairwells and atria. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
Muswell Hill sits about 2 km from Crouch End and 2 km from Wood Green, and we cover the whole N10 postcode district and the roads in between.
