Kingston upon Thames applies standard suburban householder control across New Malden, a settled inter-war family market with few conservation constraints and a large Korean community.


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 Kingston upon Thames.
Building regulations drawings for a New Malden project turn the design into a construction-ready set — Part A structure, Part B fire, Part L thermal, Part M access — for Kingston Council Building Control or an approved inspector. On KT3's inter-war bay-fronted semis and terraces around new, the recurring details are steel beams over knocked-through ground floors, loft floor build-ups, and insulation upgrades to solid period walls around New Malden, Motspur Park fringe, Coombe fringe, Old Malden fringe.
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 New Malden, Motspur Park fringe, Coombe fringe, Old Malden fringe in KT3, the dominant property is inter-war bay-fronted semis and terraces around new malden, with some edwardian and post-war infill. 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 Kingston Council judges each on design quality and neighbour impact. We survey the specific New Malden property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the KT3 streetscape.

Because KT3 is a settled family suburb of inter-war bay-fronted semis — ideal for rear and side extensions and hip-to-gable loft conversions as families grow. With few conservation constraints, much of the work runs on the Permitted Development route, which we confirm with a Lawful Development Certificate.
Usually yes on the semis — a hip-to-gable plus rear dormer within the 50 cubic metre volume allowance, confirmed by a Lawful Development Certificate. We check the roof head height and draw the scheme for Building Control too, which is essential for the new floor and stair.
Often, on the wider semi plots — a wrap-around ground-floor extension or a two-storey side addition, subject to Kingston's design and neighbour-amenity policy on the 45-degree test. We design within those limits and produce the planning and Building Regulations drawings together.
New Malden offers strong value for south-west London families.
Kingston Council charges its own statutory application fee (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 KT3 address.
For a KT3 project across New Malden, Motspur Park fringe, Coombe fringe, Old Malden 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 Kingston Council (8 weeks for a householder application). We carry the New Malden application through every officer query to the decision.
New Malden (KT3) sits primarily in Kingston upon Thames, so applications are decided by Kingston Council. We confirm the planning route for your exact address before quoting.
Almost always. Any structural work behind building regulations drawings in New Malden — 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 Kingston Council Building Control or an approved inspector. On KT3'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. 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 KT3 homes.

Every KT3 postcode district we draw in, the stock that dominates it and the authority that validates a building regulations package there. KT3 fees below are the statutory England rates for 2026, not building regulations package estimates.
| Postcode | Area | Dominant stock | What it means for a building regulations package |
|---|---|---|---|
| KT3 | New Malden | Edwardian villas, 1930s semi-detached | A KT3 address in New Malden can route building control through Kingston Council or through an approved inspector. Both discharge the same duty; the fee and the inspection timetable are what differ. |
| KT3 | Coombe | 1930s detached, Edwardian villas | Coombe is inside KT3. Building control is not a council monopoly: an approved inspector can take the same job, discharging the same duty under the Building Regulations, wherever the address sits. |
| KT1 | Kingston upon Thames | Georgian fragments, Victorian terraces, 1930s semi-detached | Adjoining district to KT3. Building control here can go to Kingston upon Thames or to an approved inspector, on the same terms as in KT3. |
| KT2 | Kingston / Norbiton | Georgian fragments, Victorian terraces, 1930s semi-detached | Adjoining district to KT3. Building control here can go to Kingston upon Thames or to an approved inspector, on the same terms as in KT3. |
| KT5 | Surbiton / Tolworth | Edwardian villas, mansion blocks | Adjoining district to KT3. Building control here can go to Kingston upon Thames or to an approved inspector, on the same terms as in KT3. |
Roof pitch, wall build-up and plot depth change every few KT3 streets, and each one changes what a building regulations package can achieve at that address.
Conservation areas covering KT3 (New Malden): Kingston Council runs 22, and Kingston Old Town, Surbiton, Hampton Wick are the ones KT3 (New Malden) owners meet most. A building regulations package inside a KT3 (New Malden) conservation area loses permitted development, so the KT3 (New Malden) submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Kingston Old Town a building regulations package is judged on the street elevation first.
No blanket Article 4 over KT3 (New Malden): Kingston Council has not withdrawn permitted development across KT3 (New Malden), so a building regulations package outside a KT3 (New Malden) conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a KT3 owner wants on file.
The building fabric around KT3 (New Malden): Edwardian villas in Surbiton and New Malden; Victorian terraces in Kingston central; 1930s semi-detached in Chessington and Tolworth; post-war in New Malden. Outer south-west London suburban; generally permissive; riverside conservation areas add character in Kingston town. A building regulations package in KT3 (New Malden) is scoped against that stock first, because it decides whether the scheme runs as permitted development, a £274 Lawful Development Certificate, or a full £548 application to Kingston Council.
