W14 spans Hammersmith & Fulham and Kensington & Chelsea; conservation control is strong around Barons Court, and the Earls Court scheme borders the area.
If your property sits elsewhere in the borough, the borough-wide page for structural calculations in Hammersmith and Fulham covers the same service across every ward.
Structural calculations for a West Kensington project size the beams, lintels, foundations and loft floor for your specific W14 property. A chartered engineer signs off the steelwork for knocked-through walls, rear openings and roof conversions on W14's grand victorian terraces and mansion blocks around, and the calculations form part of the Building Regulations submission to Hammersmith & Fulham Council.
Chartered structural engineer calculations for every residential intervention in West Kensington — steel beams, lintels, pad foundations, wall removals, loft floor joists, underpinning. Eurocode-compliant, Building Control-ready.
Across West Kensington, Barons Court, Olympia, Holland Park fringe in W14, the dominant property is grand victorian terraces and mansion blocks around west kensington and barons court, with artists' studio houses near holland park. 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 Hammersmith & Fulham Council judges each on design quality and neighbour impact. We survey the specific West Kensington property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the W14 streetscape.

Yes, but the handsome Victorian terraces around Gledstanes Road and Castletown Road sit in the Barons Court conservation area, so rear and side extensions and roof changes need full planning with a Heritage Statement rather than Permitted Development. We design to match the period detailing and submit to Hammersmith & Fulham.
W14 straddles the boundary — West Kensington and Barons Court largely sit in Hammersmith & Fulham, with the eastern edge toward Holland Park in Kensington & Chelsea. The two councils apply different conservation and basement controls, so we confirm your exact authority before quoting.
The major Earls Court / West Kensington regeneration borders W14, bringing thousands of new homes and improved public realm, supporting values. For a house project the binding controls remain Permitted Development limits and the local conservation area, which we check for your address.
Yes. The mansion blocks around West Kensington and Olympia usually have freeholder controls alongside council planning, and any external change needs full consent. We produce drawings that satisfy both the freeholder and the council, and handle Party Wall matters between flats.
With West Kensington property at around £550,000 for a flat and £1.2m-£2m for a house, the professional drawing fee is a small fraction of the value the work adds to W14's grand victorian terraces and mansion blocks around.

We quote the drawings as one fixed price and the free site survey covers every W14 address.

Almost always. Any structural work behind structural calculations in West Kensington — 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 Hammersmith & Fulham Council Building Control or an approved inspector. On W14'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 West Kensington (W14) property at around £550, 000 for a flat and £1.2m-£2m for a house, a well-designed extension or loft typically returns more than it costs in added floor area and sale value. 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 W14 homes.
