Hip-to-Gable Loft Conversion Drawings in Coombe KT2
Fixed-fee, MCIAT-chartered hip-to-gable loft 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.

Hip-to-Gable Loft Conversion Drawings for Coombe (KT2) homes: the package and the process
Every hip-to-gable loft 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.
Many London semi-detached and end-of-terrace houses, particularly the inter-war suburban stock that rings much of the city, were built with a hipped roof — sloped on all sides rather than finished with a flat gable end. That side slope wastes usable loft volume, and a hip-to-gable conversion reclaims it by extending the sloping hip out to a full vertical gable wall, squaring off the roof and opening up far more headroom along that side of the loft than the original roof shape allowed.
DrawingsDirect draws hip-to-gable conversions across outer and suburban London every week, usually alongside a rear dormer to maximise headroom over the stairwell. Because the hip-to-gable route is frequently permitted development, we check your eligibility first — and where a dormer, a mansard or a combination would use your roof better, we say so before you commit to a design. Every drawing set is produced by MCIAT-chartered architectural technologists, with structural calculations for the new gable wall coordinated in-house rather than farmed out to a separate engineer.
What is a hip-to-gable loft conversion?
A hipped roof slopes inward on all sides, including the end wall, rather than finishing in a flat vertical gable. A hip-to-gable conversion rebuilds that sloping hip as a vertical wall, in line with the existing side elevation below, squaring off the roof shape and creating a much larger, more usable loft footprint along that side without altering the rear or front roof slopes at all. It is one of the more straightforward roof alterations to build, because the new gable wall follows the line of the existing external wall rather than introducing a new roof form, which keeps both the design and the construction relatively contained compared with a full mansard rebuild.
- Suits semi-detached and end-of-terrace houses with a hipped roof on the side elevation
- Squares off the roof by rebuilding the sloping hip as a vertical gable wall
- Leaves the front and rear roof slopes untouched
Is a hip-to-gable loft conversion permitted development?
Often, yes. For semi-detached and detached houses, permitted development rules allow more than one hip to be converted to a gable, provided the new roof does not exceed the height of the existing ridge and the total additional volume stays within the usual allowance — 50 cubic metres for detached and semi-detached homes. The new gable wall and roof materials should match the existing building, and the rules tighten or disappear entirely inside a conservation area or under an Article 4 direction, both of which we check before recommending the route. Where a previous owner has already extended into the roof or added a large outbuilding, the remaining volume allowance can be smaller than expected, so we always confirm the running total against your specific property rather than assuming the full allowance is still available.
