Flat Conversion Drawings in Coombe KT2
Fixed-fee, MCIAT-chartered flat conversion drawings for Coombe (KT2) homeowners — Royal Borough of Kingston upon Thames validation and local constraints handled from the start.
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 even though Kingston operates no Article 4 directions a boundary check remains essential, because the low-density, tree-rich character means conservation-area consent and tree constraints often shape what can be built.
Planning in Coombe (KT2): what to know before you apply
Kingston has no Article 4 directions, so outside the conservation areas many householder projects fall under permitted development. Within the Coombe conservation areas, conservation-area consent applies to demolition 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.

Flat Conversion Drawings for Coombe (KT2) homes: the package and the process
Every flat conversion drawings we prepare for an Coombe property is drawn to Royal Borough of Kingston upon Thames’s validation standards and tuned to the KT2 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
Converting a house into flats is one of the few residential projects in London that always needs planning permission, whatever the size of the property or the number of units created. Splitting a single dwelling into two or more self-contained homes is treated as development regardless of whether any external work is proposed, because the change affects how the building is used and how many households occupy it.
DrawingsDirect draws house-to-flats conversions from the first survey through to a submission-ready planning and building-regulations package. Sound insulation between units, separate escape routes, individual services and London's minimum space standards are designed in from the layout stage, not retrofitted once the council asks for them — which is a large part of why our schemes are approved first time.
Do I need planning permission to convert a house into flats?
Yes, always. Converting a single dwelling into two or more self-contained flats is a change from one home to several, and that subdivision is treated as development requiring a full planning application — there is no permitted development route that allows it, regardless of the property's size or whether the exterior changes at all. The application has to demonstrate that each flat meets space, layout, amenity and parking standards in its own right, not just that the building as a whole is being used sensibly.
Boroughs also weigh the loss of a family-sized house against their local housing policy, since converting a larger house into several flats reduces the stock of homes suited to families even as it adds smaller units. We take that policy context into account when advising on layout and unit numbers, rather than simply maximising the number of flats the floor area could technically support.
What sound insulation is required between flats?
Part E of the building regulations sets minimum sound insulation standards for the walls and floors separating flats, covering both airborne and impact sound. Where an existing house is subdivided, the drawings specify how the party floors and walls between units will be upgraded — additional layers, resilient bars, or a floating floor — and pre-completion sound testing is normally required before the flats can be signed off. Getting this detail right on the drawings from the outset matters, because retrofitting sound insulation after a failed test usually means taking up a finished floor or ceiling that has already been decorated.
