House extensions in Palmers Green are dominated by single-storey rear and side-return additions on N13's edwardian and inter-war bay-fronted semis and terraces, with double-storey and wrap-around schemes where the plot allows. Enfield Council weighs depth, height and neighbour daylight; many extensions across Palmers Green, Broomfield Park, Bowes Park fringe are Permitted Development, which we confirm with a Lawful Development Certificate before you build.
The whole spectrum — rear extensions, side returns, wraparounds, double-storey, basement digs. Planning-led design with detailed technical phase, ideal for edwardian and inter-war bay-fronted semis and terraces typical of Palmers Green.
Across Palmers Green, Broomfield Park, Bowes Park fringe in N13, the dominant property is edwardian and inter-war bay-fronted semis and terraces around palmers green, with larger houses toward broomfield park. That stock shapes what house extension drawings looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Enfield Council judges each on design quality and neighbour impact.

On N13's typically terraced and semi-detached stock, a Party Wall notice to adjoining neighbours is normally required before the steelwork. We coordinate both as part of the Complete package.
In value terms, yes. With Palmers Green (N13) property at around £350,000 for a flat and £650,000-£950,000 for a house, a well-designed extension or loft typically returns more than it costs in added floor area and sale value, while our fixed drawing fee from £1,225 keeps the professional cost predictable.
