Measured Building Surveys · W4 Chiswick
W4 is mostly in Hounslow; Bedford Park carries an Article 4 direction and is one of the most architecturally protected suburbs in London.
This page covers one part of the borough. For the full picture — fees, timelines and the council's current position — read measured building surveys in Hounslow.
A measured building survey captures your Chiswick property exactly — every wall, opening, level and boundary — as the accurate base for design and planning drawings. On W4's older terraced and villa stock around Chiswick, Bedford Park, Grove Park, Turnham Green, walls are rarely square, so a laser-measured survey prevents costly errors before Hounslow Council ever sees the application.

Across Chiswick, Bedford Park, Grove Park, Turnham Green in W4, the dominant property is victorian and edwardian terraces and the celebrated arts-and-crafts houses of bedford park, with riverside houses along the chiswick mall. That stock shapes what measured building survey looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Hounslow Council judges each on design quality and neighbour impact. We survey the specific Chiswick property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the W4 streetscape.

Strongly. Bedford Park is a pioneering arts-and-crafts suburb with a conservation area and an Article 4 direction that removes many Permitted Development rights — so even windows, doors, roof tiles and front boundaries are controlled, and full planning with a Heritage Statement is normally required. We design to the suburb's distinctive Norman Shaw detailing and submit to Hounslow.
Yes. The Victorian and Edwardian terraces around Grove Park and Turnham Green suit a side-return kitchen extension, within Permitted Development depth limits outside the conservation areas. Inside Bedford Park or the Mall, full planning applies. We confirm the route and draw to Hounslow's checklist.
Most of Chiswick and Bedford Park sits in Hounslow, with a small northern edge toward Ealing. Conservation and Article 4 controls are extensive here, so we confirm your exact authority and designation before quoting and submit accordingly.
Yes. The Chiswick Mall houses are in a conservation area, many are listed, and they sit in the Thames flood zone, so changes need full planning, often Listed Building Consent, and a flood-risk assessment. These are specialist projects; we provide measured surveys and heritage drawings to the required standard.
With Chiswick property at around £550,000 for a flat and £1.4m-£2m for a house, the professional drawing fee is a small fraction of the value the work adds to W4's victorian and edwardian terraces and the celebrated. Hounslow 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 W4 address.
For a W4 project across Chiswick, Bedford Park, Grove Park, Turnham Green, 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 Hounslow Council (8 weeks for a householder application). We carry the Chiswick application through every officer query to the decision.
Chiswick (W4) sits primarily in Hounslow, so applications are decided by Hounslow Council. Conservation areas within W4 include Bedford Park (Article 4), Chiswick Mall, Grove Park, Turnham Green, 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 measured building survey in Chiswick — 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 Hounslow Council Building Control or an approved inspector. On W4'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 Chiswick (W4) property at around £550, 000 for a flat and £1.4m-£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 W4 homes.

Every W4 postcode district we draw in, the stock that dominates it and the authority that validates a measured building survey there. W4 fees below are the statutory England rates for 2026, not measured building survey estimates.
| Postcode | Area | Dominant stock | What it means for a measured building survey |
|---|---|---|---|
| W4 | Chiswick / Bedford Park | Arts & Crafts villas (listed) | Chiswick / Bedford Park is split at W4. Either Hounslow Council or Ealing Council can determine a measured building survey here, so the W4 address is checked against both policies maps first. |
| W4 | Chiswick | Edwardian villas, Victorian terraces | No consent is required to survey a W4 property in Chiswick. The survey comes first so that whatever Hounslow Council is later asked to decide rests on measured fact rather than an assumption about the existing building. |
| W4 | Turnham Green | Edwardian villas | Turnham Green sits inside W4. A measured survey needs no permission from anyone; it is the dimensioned record of what is already there, and the base any later W4 application is drawn on. |
| W4 | Bedford Park | Arts & Crafts villas (listed) | Bedford Park sits inside W4. A survey is a record, not an application, so nothing is granted or refused at this stage; its accuracy is what decides whether the drawings built on it survive scrutiny. |
| TW3 | Hounslow | 1930s semi-detached, post-war flats | Adjoining district to W4. A survey is a record rather than an application, so nothing about it changes at the Hounslow boundary. |
| TW4 | Hounslow West | mixed stock | Adjoining district to W4. A survey is a record rather than an application, so nothing about it changes at the Hounslow boundary. |
| TW5 | Heston / Cranford | mixed stock | Adjoining district to W4. A survey is a record rather than an application, so nothing about it changes at the Hounslow boundary. |
| W3 | Acton | Victorian and Edwardian terraces | Adjoining district to W4. Surveying needs no consent here either — Ealing has no say in it, and the survey is the same record whichever side of the line the property sits. |
| W5 | Ealing | Edwardian villas, Victorian terraces | Adjoining district to W4. Surveying needs no consent here either — Ealing has no say in it, and the survey is the same record whichever side of the line the property sits. |
| W7 | Hanwell | Edwardian villas, 1930s semi-detached | Adjoining district to W4. Surveying needs no consent here either — Ealing has no say in it, and the survey is the same record whichever side of the line the property sits. |
| W13 | West Ealing | Edwardian terraces | Adjoining district to W4. Surveying needs no consent here either — Ealing has no say in it, and the survey is the same record whichever side of the line the property sits. |
Roof pitch, wall build-up and plot depth change every few W4 streets, and each one changes what a measured building survey can achieve at that address.
