Structural Calculations · W5 Ealing
Ealing applies conservation control across several W5 villa suburbs; the large plots make rear and side extensions a strong local market.
The borough-level guide to structural calculations in Ealing sets out how the same work is handled across the rest of the authority.
Structural calculations for a Ealing project size the beams, lintels, foundations and loft floor for your specific W5 property. A chartered engineer signs off the steelwork for knocked-through walls, rear openings and roof conversions on W5's substantial edwardian and victorian villas and semis, and the calculations form part of the Building Regulations submission to Ealing Council.
Chartered structural engineer calculations for every residential intervention in Ealing — steel beams, lintels, pad foundations, wall removals, loft floor joists, underpinning. Eurocode-compliant, Building Control-ready.
Across Ealing, Ealing Broadway, Pitshanger, Montpelier in W5, the dominant property is substantial edwardian and victorian villas and semis, inter-war housing and mansion blocks across ealing, 'queen of the suburbs'. That stock shapes what structural calculations 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 Ealing property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the W5 streetscape.

Because W5 is full of substantial Edwardian and Victorian villas and semis on generous plots around Pitshanger and Montpelier — ideal for rear, side and double-storey extensions and large loft conversions as families grow. We've drawn the full range here to Ealing's standards, on both Permitted Development and full-planning routes.
Ealing Broadway on the Elizabeth line has cut journey times across London, reinforcing W5's status as a premium family suburb and supporting values. For a house project the binding controls remain Permitted Development limits and the local conservation designation, which we check for your road.
Often, yes. The larger semis and detached houses around Mount Park Road and Castlebar Road have the plot and separation for a two-storey side or rear extension, subject to Ealing's design and neighbour-amenity policy. We design within those limits and draw the scheme for planning and Building Control.
Ealing Green, Montpelier, Pitshanger and Mount Park all carry conservation designations within W5, controlling materials, bays and roofscape. We check your exact address, because it determines whether you need full planning and a Heritage Statement rather than a Lawful Development Certificate.
With Ealing property at around £450,000 for a flat and £900,000-£1.4m for a house, the professional drawing fee is a small fraction of the value the work adds to W5's substantial edwardian and victorian villas and semis. Ealing Council charges its own statutory application fee on top (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 W5 address.
For a W5 project across Ealing, Ealing Broadway, Pitshanger, Montpelier, 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 Ealing application through every officer query to the decision.

Almost always. Any structural work behind structural calculations in Ealing — 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 W5'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 W5 homes.

Every W5 postcode district we draw in, the stock that dominates it and the authority that validates a structural calculation package there. W5 fees below are the statutory England rates for 2026, not structural calculation package estimates.
| Postcode | Area | Dominant stock | What it means for a structural calculation package |
|---|---|---|---|
| W5 | Ealing | Edwardian villas, Victorian terraces | W5 covers Ealing only; Ealing Council handles the structural calculation package. |
| W5 | Ealing Broadway | Edwardian villas, Victorian terraces | Ealing Broadway sits inside W5. Calculations from here are checked under the Building Regulations — by Ealing Council building control or by a private approved inspector, and that choice is the owner's. |
| W5 | Pitshanger | Edwardian villas | Pitshanger sits inside W5. Calculations from here are checked under the Building Regulations — by Ealing Council building control or by a private approved inspector, and that choice is the owner's. |
| W3 | Acton | Victorian and Edwardian terraces | Adjoining district to W5. The structural test is national, so the same approved documents apply on both sides of the Ealing line. |
| W7 | Hanwell | Edwardian villas, 1930s semi-detached | Adjoining district to W5. The structural test is national, so the same approved documents apply on both sides of the Ealing line. |

Roof pitch, wall build-up and plot depth change every few W5 streets, and each one changes what a structural calculation package can achieve at that address.

Article 4 and your W5 (Ealing) structural calculation package: Article 4 for HMOs in specific streets in Acton, Ealing and Southall.
