Single storey 6m rear extension erection of hip to gable with rear dormer and roof-lights





73 Plumpton Avenue, London, RM12 6BB


Development Type

Rear extension, Roof extension with rear dormer

Proposed Development

Single storey 6m rear extension, erection of hip to gable with rear dormer and roof-lights


4D Planning's Role

4D Planning advised the client on the potential to extend the property to create additional habitable space. We advised the client to apply for Prior Approval for a large 6m deep extension to the rear of the ground floor and to apply separately for a lawful development application for the roof extension, loft conversion with rear dormer and rooflights. 4D Planning prepared the architectural drawings for each application and obtained Havering Council's approval for both applications. 4D Planning was then instructed to prepare the Building Regulations to satisfy Building Control and to liaise with the Structural Engineer. We also produced the Tender Pack for the builders.
