KT2 north of Kingston takes in Coombe, an exclusive district of large detached houses set in landscaped grounds around the Coombe Hill and Coombe Wood golf courses, where owners typically plan a substantial extension, remodelling or an occasional new-build replacement.

Several Coombe conservation areas overlap this outcode, so a boundary check remains essential, because the low-density, tree-rich character means the conservation-area rules and tree constraints often shape what can be built.

Planning in Coombe (KT2): what to know before you apply

None of Kingston's Article 4 directions removes householder permitted development, so outside the conservation areas many householder projects fall under permitted development. Within the Coombe conservation areas, demolishing an unlisted building needs planning permission and larger schemes are best taken through a full householder application, with tree preservation orders checked early.

Typical Coombe housing stock

The Coombe conservation areas hold large Victorian, Edwardian and 20th-century detached houses in spacious landscaped grounds, several by notable architects, set among golf courses and mature woodland north of Kingston town centre.

Building Regulations Drawings for Coombe (KT2) homes: the package and the process

A Full Plans submission is a technical argument, not a picture. The sheets carry construction build-ups for floors, walls and roof, insulation values and junction details, drainage runs and invert levels, fire escape routes and protected stairs, ventilation provision and the structural elements that carry it all. Building Control checks each against the Approved Documents before work starts.

We draw the engineer's structural design onto the architectural sheets, so the beam sizes on the calculations are the beam sizes on the sections, and the openings your builder prices are the openings that were approved. Where a detail is unusual, we draw it rather than leave it to be resolved on site.

Construction details follow the existing fabric. Solid brick walls, suspended timber floors and uninsulated roofs each need a different build-up to reach the required performance, and a terrace has party wall junctions to detail that a detached house simply does not.

What do building regulations drawings cover?

A building control package translates the approved design into a buildable, compliant specification.

  • Construction sections and detailed junctions
  • Structural drawings and calculations (steel beams, foundations, loadings)
  • Part L thermal performance and insulation specification
  • Fire safety — escape routes, protected structure, alarms
  • Drainage and ventilation layouts

Full Plans or Building Notice — which should I choose?

A Full Plans application has your drawings checked and approved by Building Control before work starts, giving certainty and a document lenders and buyers like to see. A Building Notice lets simpler work start sooner but is inspected as it proceeds, with less up-front certainty. For most London extensions and loft conversions we recommend Full Plans, and prepare the package accordingly. Building regulations are a separate consent from planning permission, and the two are often confused — the explainer on permitted development rights sets out which projects escape a planning application but still need building-regs approval.

Why coordinate structural calculations with the drawings?

When the engineer's steels, padstones and bearings are drawn onto our own sheets, the steel schedule matches the drawings and the builder never waits on a missing detail. It closes the classic gap between one firm's drawings and another firm's calculations that nobody has checked against them.

FAQ

Building Regulations Drawings in Coombe KT2 — FAQs

Do I need building regulations approval as well as planning permission?+
Almost always, yes. Planning permission covers what the building looks like; building regulations cover how safely it is built. Most extensions and loft conversions need both.
How long does Building Control approval take?+
A Full Plans application is typically assessed within about five weeks. We prepare a complete package and respond to any conditions promptly, so approval is not held up by missing detail.
Can building regulations drawings be done after planning approval?+
Yes. Many homeowners secure planning permission first, then commission the building regulations package before starting on site. We can pick a project up at either stage.
Are structural calculations included?+
No, not in the building regulations fee. They are a separate service from £745, prepared by a named, insured engineer, or you can use your own engineer; either way we draw the beams and padstones onto the set so your builder has everything to price and build. Our all-inclusive packages include them.
Can you submit to Building Control for me?+
Yes, we prepare and submit the Full Plans package and respond to any Building Control queries.
Do I need planning permission for an extension in Kingston?+
The interwar semis of New Malden, Chessington and Tolworth often keep permitted development rights for rear extensions and lofts, so a full application isn't always needed. In a conservation area such as Surbiton, Coombe or the town centre, side extensions, dormers and other roof enlargements, rear extensions over one storey and cladding are not permitted development. Riverside flood-zone constraints are a separate check. We check your address first and can confirm permitted development with a Lawful Development Certificate.
My Kingston home is near the river — does flood risk affect my plans?+
It can. Riverside plots near Kingston lie within the Thames flood zone, and the council expects flood-risk and finished-floor-level considerations to be addressed for works there. We evidence these within the application so the council can validate and approve without repeated revisions.
Can I build a larger extension on a Coombe plot?+
Often, yes. The substantial detached houses on the Coombe hill sit on generous plots that make larger rear and double-storey extensions viable, subject to design and amenity policy. We design to use the plot fully within permitted-development allowances or a well-evidenced full application, checking the limits for detached homes first.
How long does the Royal Borough of Kingston take to decide?+
Kingston has eight weeks beginning the day after a valid application comes in, unless extra time is agreed in writing. Conservation and riverside cases can involve additional consultation.
How much do planning drawings cost in Kingston?+
We agree a fixed fee before starting, taken from our published price list, with free redraws until Kingston approves. A suburban semi extension and a riverside or Coombe scheme differ in the evidence required, so we quote once we understand your address and project rather than by the hour.
