L-shape rear dormer roof extension, Juliet balcony, single storey extension





80 Darrell Road, London, SE22 9NL


Development Type

Roof extension, Juliet balcony, single storey extension

Proposed Development

Erection of an L-shape rear dormer roof extension to the main rear roof slope and to the outrigger roof slope, incorporating a juliet balcony; the installation of x2 rooflights to the front roof slope; and the erection of a ground floor single storey 'side and rear return' extension incorporating a lantern skylight.


4D Planning's Role

4D Planning were instructed to advise the client on the feasibility of extending the single family dwelling to maximise the habitable space. We advised to apply for a large roof extension and loft conversion under PD (permitted development) and to apply for a single storey extension in the same application. Once approved we advised to apply separately for householder planning permission to infill the side, by applying for a side return extension. We were instructed to prepare the two applications and all architectural drawings. Southwark Council granted planning permission and a lawful development certificate for the proposed works. 4D Planning then produced the building regulations and tender pack for the builders and building control.
