Planning in Kingston upon Thames — the detail
Kingston upon Thames — one of only four royal boroughs in England — runs from the Thames at Kingston and Surbiton up to the wooded Coombe estate on the Wimbledon Common fringe. Its 27 conservation areas include Kingston Old Town, Riverside South, Grove Crescent and Fairfield and Knights Park near the centre, the Surbiton Town Centre and Surbiton Hill Park areas, and the exclusive Coombe Hill, Coombe Wood and Coombe House areas, where large detached houses in mature grounds attract some of the borough's most prominent extension and replacement-dwelling schemes.
Kingston's Article 4 directions are, for the most part, not householder restrictions: they protect the borough's town centres and key employment areas — chiefly by removing the permitted development right to convert offices and commercial premises to residential — so what narrows a homeowner's options is conservation-area designation and, in the older stock, listed status. The council's Residential Design SPD sets the design expectations for householder extensions, and a Riverside Public Realm SPD guides work along the Thames frontage.
Outside the conservation areas, Kingston's Victorian, Edwardian and interwar stock in Surbiton, New Malden and Old Malden supports the usual rear extensions, side returns and loft conversions, much of it under permitted development. With the conservation areas concentrated around the town centres, the riverside and Coombe, the address-level check is what tells you whether a project is a prior-approval formality or a full application.
Policy detail lives in the Kingston upon Thames local plan and applications are submitted via the Kingston upon Thames planning portal.

Article 4 directions in Kingston upon Thames
Real · planning.data.gov.ukKingston's Article 4 directions, recorded on the council's own register rather than the national planning.data.gov.uk dataset, mostly protect the borough's town centres and key employment areas — chiefly removing the permitted development right to convert offices and commercial premises to homes — rather than restricting householder extensions. For homeowners, conservation-area designation and listed status are what narrow extension rights; check the area report for what applies at a specific address.

What gets built in Kingston upon Thames
Surbiton, New Malden and Old Malden terraces extend under PD; the town-centre, riverside and Coombe conservation areas need a full application.
Rear extension in Kingston upon Thames →Common on Surbiton's Victorian terraces; conservation designation is the main control on the shared flank and roofline.
Side return extension in Kingston upon Thames →Routine on the Surbiton, New Malden and Worcester Park stock under PD; conservation areas require a full application and careful dormers.
Loft conversion in Kingston upon Thames →A full application with structural and flood-risk evidence is the norm, especially near the Thames and on the Coombe slopes.
Basement extension in Kingston upon Thames →Suits the larger gardens of Surbiton, New Malden and Coombe under PD; conservation-area designation and height and incidental-use limits are the constraints.

Who to talk to about a Kingston upon Thames property
Constraint data tells you what applies. It does not draw a scheme, argue a case with Kingston upon Thames's planners, or inspect a building. For that this site points at two separately regulated practices — which one you need depends on the job in hand.
The architect's door: designing the scheme and getting it consented — drawings, the planning application and the building-regulations package.
- Residential design for extensions, lofts, basements and conversions
- Planning applications, pre-application advice and appeals
- Lawful development certificates
- Building-regulations and technical design drawings
- Conservation-area design and listed building consent applications
The chartered-surveyor door: professional judgement on condition, risk, party wall matters and leasehold process.
- Building surveys, RICS home surveys and defect diagnosis
- Party wall matters and awards
- Technical due diligence before a purchase
- Leasehold and major-works advisory (Section 20)
- Dilapidations and building pathology
Both practices are independent and separately regulated — Hampstead Chartered Surveyors & Building Consultancy is an RICS-regulated firm (Firm Reg. 923064); Hampstead Architecture and Planning are ARB-registered architects. We publish no fees for their work: each quotes directly for the job in front of them. Your enquiry goes to the practice you choose — we never pass your details to builders or other third parties.
