Permitted25/01735/FULSubmitted over a year agoRear extension

Northumberland Avenue Bexley DA16 2QN

The proposed development involves the construction of a new wrap-around ground-floor extension with a flat GRP or layer felt roof, rear UPVC windows and doors, and a new entrance porch way to the front side portion of the property. Internally, the existing staircase will be relocated, and on the first floor, there will be a new first-floor rear extension forming a new bedroom space compliant with the 45-degree rule to the neighbours' windows. To the roof of the extension, there will be a new pitched roof with a flat felt or GRP roof which will encompass the whole of the first-floor side extension currently present to match the local character of the road.
