Erection of a single-story rear extension and loft conversion with rear dormer and rooflights





46 Marchmont Road, Wallington SM6 9NU


Development Type

Single storey rear extension, roof extension with dormer and rooflights

Proposed Development

Erection of a single-storey rear extension and conversion of loft space involving alterations to existing roofline, a dormer extension at rear and rooflights to front and side roof slopes.


4D Planning's Role

4D Planning designed a rear dormer extension to compliment the design of the house while maximising the internal space to provide as much natural light and ventilation as possible. The new loft conversion will feature several rooflights and a large ensuite bedroom. The ground floor rear extension has been designed to meet the permitted development rights while retaining the size of the garden. The application was submitted within 2 weeks of instruction. Sutton Council granted a lawful development certificate within 3 weeks from submission as there was no consultation with neighbours. The whole process took less than 5 weeks from instruction. 4D Planning are now in the process of preparing the building regulations for building control and tender pack for the builders.
