Planning and building regulation drawings in Southgate Green (N14)
N14 wraps around a genuine green, the kind most London postcodes lost a century ago. Georgian and early Victorian houses face onto it, more than thirty of them listed alongside assorted garden walls, gate piers and other structures that carry the same protection. Walk a few streets back and the picture changes: Edwardian villas and interwar semis line Conway Road and the roads around it, the sort of housing stock that behaves very differently under planning law than the terraces facing the green itself.

That split matters more here than in most districts, because Southgate Green sits inside a conservation area with its own Article 4(2) direction dating to 2009. The Green, Waterfall Road and Ulleswater Road are among Southgate Green's named streets, and homeowners across the area should never assume an extension or replacement window automatically counts as permitted development, since a street-facing frontage can need a full application instead. Further out, on the Edwardian and interwar streets around Conway Road, ordinary permitted-development rules can still apply, so the first job on any N14 project is working out which side of that line a house falls on.
We draw for both situations. A loft conversion on an Edwardian semi away from the green is often a straightforward permitted-development set. A rear extension on a listed Georgian house facing the green usually needs a planning application and, separately, listed building consent for anything touching the historic fabric, even on an adjoining or attached structure. Getting that distinction right before anyone starts drawing saves weeks later.
Planning in Southgate Green: what to know before you apply
Enfield runs a borough-wide Article 4 direction stripping permitted development rights for HMO conversions everywhere, plus its own conservation-area controls layered on top in places like Southgate Green. Southgate Green's conservation area carries a direction dated 2009 that strips away permitted development specifically for anything facing the street, so porches, windows, cladding and other front-facing changes that would need no paperwork elsewhere require a full planning application on these houses. Where a building is one of the green's many listed structures, listed building consent runs alongside the planning application and covers internal changes too, not just what shows from the street. Further from the green, where interwar semis dominate, a rear extension or a loft reshaped from hip to gable can often proceed without planning permission at all, though we verify that with the council on every project rather than assume it.
Applications are decided by London Borough of Enfield — its planning pages.
