Building Regulations Drawings in Ham |

No Article 4 Direction covers Richmond upon Thames, which keeps the Ham permitted-development route open on unlisted houses. The fabric of Ham is Georgian common, post-war estate, so a TW10 proposal is judged on fit before it is judged on size. Ham Common is the designation that most often reshapes a Ham proposal; Richmond upon Thames carries 72 of them. The designation map is read street by street in Ham.

We map how Article 4 directions bite across TW10 before a line is drawn. What can be built on a Ham plot is decided by the georgian villas — the original rear wall position first, the Ham Common roofline second. The borough policy layer over every TW10 address is set out on Richmond upon Thames planning. The Ham survey then carries into loft conversion drawings in Ham if the project runs on to construction.

Before Richmond Council determines anything, London Borough of Richmond upon Thames has to validate the Ham submission — one to two weeks, longer if a plan is missing. A Ham project opens with an on-site laser survey, which is what makes the later Richmond Council submission robust against a validation query.

Statutory periods: 8 weeks from validation for a householder application, 13 weeks for a major scheme, 6 weeks for prior approval with a 21 days neighbour consultation, and 5 weeks for a full plans building control submission. A party structure notice requires one month notice and two months where excavation is involved.

Once Richmond Council registers the Ham case, the officer site visit usually follows within a fortnight. Scales, north point and drawing numbers all follow Richmond Council validation requirements.

We design Ham schemes to answer the amenity objection before it is written. Drainage runs and manhole positions on the TW10 plot are picked up on the day.

Budget notice time on any Ham job touching a shared wall. Once consent is granted, house extension drawings follows for the TW10 property.

Ham is characterised by georgian villas, post-war estates, concentrated across TW10 in the Richmond / Ham area. Across TW10 the georgian villas repeats often enough to be predictable, once it has been measured properly. Translated to the georgian villas here: georgian solid walls here cannot take standard cavity detailing, so Part L compliance is normally argued on a fabric-first basis with internal insulation and a condensation risk analysis. On the georgian villas in Ham it sets the beam run. Richmond Council judges massing against the established Ham rhythm — the eaves and ridge lines running past Ham Common.

Richmond Council assesses Ham basements on standard grounds. The same Ham drawings carry through to architectural drawings for TW10 properties and planning permission.

What the Ham drawing pack contains

For a TW10 address the deliverables are fixed, not open-ended.

• construction floor plans for the Ham property
• sections at 1:50
• Part A structural notes
• Part L thermal build-ups

Local landmarks that shape a Ham application

• Canbury Gardens — roof profiles that set the ridge datum Richmond Council measures a Canbury Gardens dormer against.
• Richmond Park — shared flank walls, so Richmond Park party structure notices go out before work starts.
• Strawberry Hill — shared flank walls, so Strawberry Hill party structure notices go out before work starts.
• Ham Common — it fixes the local datum a Ham roof extension is judged against.
• Cassel Hospital — schemes visible from it get closer scrutiny in Richmond upon Thames.
• Grey Court School — proposals in its setting are drawn with the Ham context elevation.
• King George's Fields — schemes visible from it get closer scrutiny in Richmond upon Thames.
• Ham Common — it fixes the local datum a Ham roof extension is judged against.

Getting to a Ham survey

Surveyors travel to TW10 addresses from the studio; the nearest stations are filling station. Appointments are booked in Ham on weekdays and Saturdays, and the measured survey of a standard georgian villas takes two to three hours.

Where Ham sits

on Ordnance Survey grid reference TQ1813673150, with the River Thames shaping drainage and flood-risk questions on lower-lying TW10 plots. Those coordinates matter in practice: a site location plan for Richmond Council must be drawn to a recognised scale over the correct grid square. Source.

Practical detail for a Ham submission: we reach Ham sites via filling station; mail for Ham routes via RICHMOND; dialling code 020; heritage assets in Ham: Grade II Lady Juliana Fermor Penn. Site plans are drawn to the address as Richmond Council holds it.

Ham postcode coverage

Coverage runs across TW10 (Richmond / Ham), shared with Richmond — and Richmond Council validates against the address, so the district line matters more than the street name.

Streets and stations in Ham

Canbury Gardens, Richmond Park and Strawberry Hill are typical of the Ham streets we draw. most Ham sites are within walking distance of filling station. and Grade II Lady Juliana Fermor Penn is listed, which pulls neighbouring TW10 proposals into a setting assessment.

Areas we cover around Ham

Neighbouring coverage runs to Kew (TW9), Barnes (SW13), East Sheen (SW14), Teddington (TW11), Hampton (TW12), Whitton (TW2); the Richmond upon Thames policy is shared but the stock and the designations are not.

Two Ham jobs differ in price because of the georgian villas and the Ham Common designation, never because of hours booked.

Drawings for Ham are issued under MCIAT charter, which is the technical design and construction-detailing qualification rather than an RIBA registration. Borderline Ham sites (anything overlooking Ham Common, anything with a Ham Common frontage) go to Richmond Council for pre-application advice before we submit.

Drawings are produced by chartered members of the Chartered Institute of Architectural Technologists (MCIAT), the professional body for technical design and building-regulations competence. First-time approval across our London caseload is 98%. Statutory fees shown are those in force in England in 2026 under the Town and Country Planning (Fees for Applications) Regulations.
