Garage Conversions · 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 garage conversions in Ealing covers the same service across every ward.
Converting a garage in Hanwell reclaims it as a habitable room — home office, bedroom or kitchen-diner — on W7's semi-detached and inter-war stock. Most garage conversions are Permitted Development, but Ealing Council expects the parking and street-scene impact considered, and Building Regulations cover insulation, damp-proofing and the new floor and walls.
Turn your unused Hanwell garage into a bedroom, home office or open-plan kitchen-diner. Planning route assessment, full building regulations drawings with Part L thermal compliance, structural calculations for any removed walls.
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 garage conversion 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 garage conversion 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.

Every W7 postcode district we draw in, the stock that dominates it and the authority that validates a garage conversion there. W7 fees below are the statutory England rates for 2026, not garage conversion estimates.
| Postcode | Area | Dominant stock | What it means for a garage conversion |
|---|---|---|---|
| W7 | Hanwell | Edwardian villas, 1930s semi-detached | A garage conversion at an W7 address in Hanwell is determined by Ealing Council under its own Local Plan policies for Hanwell. |

How designation changes a W7 (Hanwell) garage conversion: Ealing Council maintains 30 conservation areas, including Pitshanger, Bedford Park, Acton Green. Inside any of them a W7 (Hanwell) garage conversion cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Bedford Park sets the tone for W7 (Hanwell) casework.
What Article 4 removes near W7 (Hanwell): Article 4 for HMOs in specific streets in Acton, Ealing and Southall. Before pricing a garage conversion we check whether the W7 address is inside the mapped area, because Ealing Council draws the W7 (Hanwell) boundary street by street rather than across the whole of W7 (Hanwell).
