Often, on the wider semi plots — a wrap-around ground-floor extension or two-storey side addition, subject to Barnet's design and neighbour-amenity policy on the 45-degree daylight rule and side-space. We design within those limits and produce the planning and Building Regulations drawings together.

Almost always.

On N3'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 Finchley Central (N3) property at around £400,000 for a flat and £750,000-£1.1m 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 £840 keeps the professional cost predictable. The bigger risk is an unapproved or non-compliant scheme — which is why council-ready drawings and a clean Building Control sign-off matter on N3 homes.
