Loft Conversions · W14 West Kensington
W14 spans Hammersmith & Fulham and Kensington & Chelsea; conservation control is strong around Barons Court, and the Earls Court scheme borders the area.
The borough-level guide to loft conversions in Hammersmith and Fulham sets out how the same work is handled across the rest of the authority.
A loft conversion in West Kensington usually takes the form of a rear or L-shaped dormer on W14's terraced houses, or a hip-to-gable plus dormer on the semi-detached and villa stock. Hammersmith & Fulham Council assesses roof additions on design and street impact, particularly near Barons Court, West Kensington, Edwardes Square / Scarsdale fringe; we confirm whether your loft is Permitted Development or needs full planning, then handle the drawings, structural calculations and Party Wall notices.
Every loft type across every West Kensington roof line — dormer, mansard, hip-to-gable, L-shape, Velux. LDC or full planning route, building regulations, structural calculations and party wall notices, all fixed price.
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 loft conversion drawings 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. Hammersmith & Fulham 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 W14 address.
For a W14 project across West Kensington, Barons Court, Olympia, Holland Park 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 Hammersmith & Fulham Council (8 weeks for a householder application). We carry the West Kensington application through every officer query to the decision.
West Kensington (W14) sits primarily in Hammersmith and Fulham, so applications are decided by Hammersmith & Fulham Council.

Almost always. Any structural work behind loft conversion drawings 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.
