House extensions in Cricklewood are dominated by single-storey rear and side-return additions on NW2's inter-war and edwardian semi-detached and terraced houses, with double-storey and wrap-around schemes where the plot allows. Brent Council weighs depth, height and neighbour daylight; many extensions across Cricklewood, Neasden, Dollis Hill, Childs Hill 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 inter-war and edwardian semi-detached and terraced houses typical of Cricklewood.
Across Cricklewood, Neasden, Dollis Hill, Childs Hill in NW2, the dominant property is inter-war and edwardian semi-detached and terraced houses, with 1930s parades and pockets of post-war estate around cricklewood and neasden. 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 Brent Council judges each on design quality and neighbour impact. We survey the specific Cricklewood property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the NW2 streetscape.

Yes.

We confirm the route and draw to Brent's validation checklist.
It's one of London's largest regeneration schemes — new homes, a Thameslink station and town centre — which is lifting values across NW2. For an individual house project the regeneration mainly improves the backdrop; your scheme is still governed by Permitted Development limits and Brent's householder policy, which we apply.
Usually yes on the semis — a hip-to-gable plus rear dormer is the standard scheme, within the 50 cubic metre volume allowance and confirmed by a Lawful Development Certificate, provided you're not in a conservation area. We check the constraints for your road and draw it for Building Control too.
With NW2 houses around £700,000-£950,000 and the Brent Cross regeneration improving the area, a well-designed rear extension or loft adds usable family space worth well above the build and drawing cost. Our fixed fee keeps the professional cost predictable.
Our fixed fee for house extension drawings in Cricklewood starts at £1,225 — no hourly billing. With Cricklewood property at around £400,000 for a flat and £700,000-£950,000 for a house, the professional drawing fee is a small fraction of the value the work adds to NW2's inter-war and edwardian semi-detached and terraced houses. Brent Council charges its own statutory application fee on top (currently £258 for a householder planning application, £578 for a full application). We quote the drawings as one fixed price and the free site survey covers every NW2 address.
For a NW2 project across Cricklewood, Neasden, Dollis Hill, Childs Hill, expect roughly 3–4 weeks from instruction to submission: week 1 the measured survey, weeks 2–3 the drawings and your revisions, then validation and the statutory determination by Brent Council (8 weeks for a householder application). We carry the Cricklewood application through every officer query to the decision.

Almost always. Any structural work behind house extension drawings in Cricklewood — new openings, steel beams, loft floors, foundations — needs Building Regulations approval covering structure (Part A), fire escape (Part B) and insulation (Part L), submitted to Brent Council Building Control or an approved inspector. On NW2'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 Cricklewood (NW2) property at around £400,000 for a flat and £700,000-£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. 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 NW2 homes.
