Yes. The Victorian terraces in the Brackenbury grid suit side-return and rear kitchen extensions and loft conversions, but most of the grid is a conservation area, so full planning with a Heritage Statement is typically required rather than Permitted Development.

Yes.

We provide the heritage and survey drawings these specialist projects require.
Usually yes, but inside the Ravenscourt conservation area a rear dormer needs full planning and front roof changes are resisted.
