Planning in Havering
Local planning rules for conservatories & orangeries in Havering.
Havering's conservation areas include Upminster Hall, Cranham, Emerson Park, Havering-atte-Bower and parts of Hornchurch. Green Belt covers most of the borough's eastern fringe restricting new development. Outside heritage and Green Belt zones, Havering is one of London's most planning-friendly authorities — hip-to-gable lofts, rear dormers, 6m rear extensions and garage conversions are routinely approved under PD or prior approval. Two-storey side extensions are commonly approved with the standard setback. The council favours brick and tile matched to existing stock.
Our planning team handles the full submission for Havering addresses including drawings, Design and Access Statements where required, and pre-application consultation with the council. We tell you whether your conservatories & orangerie is permitted development, prior approval, or full planning before you sign anything.
