Building Regulations Drawings · W7 Hanwell
Ealing controls the Hanwell Village Green and Churchfields conservation areas; the Elizabeth line has lifted demand across W7.
If your property sits elsewhere in the borough, the borough-wide page for building regulations drawings in Ealing covers the same service across every ward.
Building regulations drawings for a Hanwell project turn the design into a construction-ready set — Part A structure, Part B fire, Part L thermal, Part M access — for Ealing Council Building Control or an approved inspector. On W7's edwardian and inter-war terraces and semis around, the recurring details are steel beams over knocked-through ground floors, loft floor build-ups, and insulation upgrades to solid period walls around Hanwell, Boston Manor fringe, Churchfields, West Ealing fringe.
A construction-ready drawing package compliant with every Approved Document — Part A structure, Part B fire, Part L thermal, Part M accessibility — submitted to LABC or your approved inspector with structural calculations coordinated.
Across Hanwell, Boston Manor fringe, Churchfields, West Ealing fringe in W7, the dominant property is edwardian and inter-war terraces and semis around hanwell, with cottage-style streets near the brent valley and pockets of larger housing. That stock shapes what building regulations drawings looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Ealing Council judges each on design quality and neighbour impact. We survey the specific Hanwell property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the W7 streetscape.

Yes.

We confirm the route and draw to Ealing's checklist.
Hanwell on the Elizabeth line has cut journey times to central London and Heathrow, lifting demand and values across W7. For a house project it improves the backdrop; your scheme is still governed by Permitted Development limits and Ealing householder policy, which we apply.
The Hanwell Village Green and Churchfields conservation areas protect the older village core and the streets around St Mary's, so external changes there need full planning with a Heritage Statement. We design sympathetically and submit to Ealing.
Usually yes on the semis and terraces — a hip-to-gable plus rear dormer within the volume allowance, 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.
Ealing Council charges its own statutory application fee (currently £548 for a householder planning application, £610 for a full application). We quote the drawings as one fixed price and the free site survey covers every W7 address.
For a W7 project across Hanwell, Boston Manor fringe, Churchfields, West Ealing fringe, 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 Ealing Council (8 weeks for a householder application). We carry the Hanwell application through every officer query to the decision.
Hanwell (W7) sits primarily in Ealing, so applications are decided by Ealing Council. Conservation areas within W7 include Hanwell Village Green, Churchfields, St Mary's Hanwell, where full planning and a Heritage Statement are required. We confirm the planning route for your exact address before quoting.
Almost always. Any structural work behind building regulations drawings in Hanwell — 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 Ealing Council Building Control or an approved inspector. On W7'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. 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 W7 homes.
Householders often approach us after a neighbour used a different council. Our full range is set out for NW10, W3, W4, W5 and W13.

Every W7 postcode district we draw in, the stock that dominates it and the authority that validates a building regulations package there. W7 fees below are the statutory England rates for 2026, not building regulations package estimates.
| Postcode | Area | Dominant stock | What it means for a building regulations package |
|---|---|---|---|
| W7 | Hanwell | Edwardian villas, 1930s semi-detached | W7 covers Hanwell only; Ealing Council handles the building regulations package. |
| W3 | Acton | Victorian and Edwardian terraces | Adjoining district to W7. The Building Regulations are national; only the choice of inspector is local, and even that is not fixed by Ealing. |
| W5 | Ealing | Edwardian villas, Victorian terraces | Adjoining district to W7. The Building Regulations are national; only the choice of inspector is local, and even that is not fixed by Ealing. |
| W13 | West Ealing | Edwardian terraces | Adjoining district to W7. The Building Regulations are national; only the choice of inspector is local, and even that is not fixed by Ealing. |
Roof pitch, wall build-up and plot depth change every few W7 streets, and each one changes what a building regulations package can achieve at that address.

What Article 4 removes near W7 (Hanwell): Article 4 for HMOs in specific streets in Acton, Ealing and Southall.
