Building Regulations Drawings · TW9 Richmond
Richmond upon Thames applies some of London's tightest householder and conservation control around Kew Green, Kew Gardens and Central Richmond, with the Royal Botanic Gardens a UNESCO World Heritage Site nearby.
This page covers one part of the borough. For the full picture — fees, timelines and the council's current position — read building regulations drawings in Richmond upon Thames.
Building regulations drawings for a Richmond project turn the design into a construction-ready set — Part A structure, Part B fire, Part L thermal, Part M access — for Richmond Council Building Control or an approved inspector. On TW9's victorian and georgian terraces and villas around, the recurring details are steel beams over knocked-through ground floors, loft floor build-ups, and insulation upgrades to solid period walls around Richmond, Kew, Kew Gardens, North Sheen.
A construction-ready drawing package compliant with every Approved Document — Part A structure, Part B fire, Part L thermal, Part M accessibility — submitted to LABC or your approved inspector with structural calculations coordinated.
Across Richmond, Kew, Kew Gardens, North Sheen in TW9, the dominant property is victorian and georgian terraces and villas around richmond and kew, riverside houses, and mansion flats — a premium river market. That stock shapes what building regulations drawings looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Richmond Council judges each on design quality and neighbour impact. We survey the specific Richmond property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the TW9 streetscape.

Yes, but most of TW9 sits in the Kew Green, Kew Gardens, Central Richmond or Richmond Green conservation areas, where rear and side extensions and roof changes need full planning with a Heritage Statement rather than Permitted Development. Proximity to the UNESCO World Heritage Site at Kew also raises the bar. We design to the period and submit to Richmond.
Very. The Kew Gardens and Kew Green conservation areas protect the Victorian and Georgian character, and the council resists changes that harm the setting of the Royal Botanic Gardens World Heritage Site. We produce a careful Heritage Statement and design within those constraints for a realistic chance of consent.
Rarely — most TW9 houses are in conservation areas where Permitted Development for roof changes is removed, so a dormer needs full planning and conservation rooflights are often preferred to the street side. We confirm the designation for your road and design the scheme to suit.
With TW9 houses commonly £900,000-£1.6m, a well-designed and consented extension or loft adds substantial value and family space in one of London's most desirable river markets. The planning bar is high, so professional drawings and a strong Heritage Statement matter.
With Richmond property at around £500,000 for a flat and £900,000-£1.6m for a house, the professional drawing fee is a small fraction of the value the work adds to TW9's victorian and georgian terraces and villas around. Richmond 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 TW9 address.
For a TW9 project across Richmond, Kew, Kew Gardens, North Sheen, 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 Richmond Council (8 weeks for a householder application). We carry the Richmond application through every officer query to the decision.
Richmond (TW9) sits primarily in Richmond upon Thames, so applications are decided by Richmond Council. Conservation areas within TW9 include Kew Green, Kew Gardens, Central Richmond, Richmond 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 building regulations drawings in Richmond — 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 Richmond Council Building Control or an approved inspector. On TW9'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 Richmond (TW9) property at around £500, 000 for a flat and £900, 000-£1.6m 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 TW9 homes.

Every TW9 postcode district we draw in, the stock that dominates it and the authority that validates a building regulations package there. TW9 fees below are the statutory England rates for 2026, not building regulations package estimates.

|---|---|---|---|
| TW9 | Richmond / Kew | Georgian terraces, Victorian villas | A TW9 address in Richmond / Kew can route building control through Richmond Council or through an approved inspector. Both discharge the same duty; the fee and the inspection timetable are what differ. |

Roof pitch, wall build-up and plot depth change every few TW9 streets, and each one changes what a building regulations package can achieve at that address.
How designation changes a TW9 (Richmond / Kew) building regulations package: Richmond Council maintains 72 conservation areas, including Hampton Wick, Twickenham Riverside, Barnes Village. Inside any of them a TW9 (Richmond / Kew) building regulations package cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Hampton Wick sets the tone for TW9 (Richmond / Kew) casework.
TW9 (Richmond / Kew) permitted development status: there is no borough-wide direction from Richmond Council, so a building regulations package at a TW9 address is normally still permitted development. We certify that with a £274 Lawful Development Certificate rather than leaving a TW9 (Richmond / Kew) sale to argue it later.
