Hip-to-Gable Loft Conversion Drawings in East Dulwich SE22
Fixed-fee, MCIAT-chartered hip-to-gable loft conversion drawings for East Dulwich (SE22) homeowners — London Borough of Southwark validation and local constraints handled from the start.
East Dulwich (SE22) sits in the London Borough of Southwark, tucked between Dulwich Village, Peckham and Forest Hill. Its character comes from the tight grid of late-Victorian and Edwardian terraces — the 'Derbyshire colony' of streets off Lordship Lane, including Melbourne Grove, built in the 1870s and 1880s. Rear, side-return and loft projects on these consistent terraces are the staple here.
The Gardens conservation area lies to the north-east, off East Dulwich Road by Peckham Rye Common, and the Dulwich Village conservation area borders the district to the south, so properties near either boundary answer to heightened design scrutiny. Southwark publishes its Article 4 directions and none covers these householder streets, so many East Dulwich houses keep permitted-development rights — we confirm where an address sits relative to the conservation areas before advising.
Planning in East Dulwich (SE22): what to know before you apply
Southwark publishes its Article 4 directions and none covers the East Dulwich householder streets, so many houses retain permitted-development rights for rear and loft work. The Gardens conservation area to the north-east and the Dulwich Village conservation area to the south are the controls that matter near those boundaries, and the consistent Victorian and Edwardian terrace frontages mean dormers and elevation changes are judged against the established grain. We check an address against those designations before drawing.

Hip-to-Gable Loft Conversion Drawings for East Dulwich (SE22) homes: the package and the process
The hip-to-gable case is made on the end elevation. The drawings show the existing hipped roof and the proposed gable side by side at the same scale, with the new brickwork or tile hanging set out, the ridge extended to its new length, and the junction with any neighbouring roof made explicit.
Because the work changes the roof at the boundary, the section and the end elevation also have to show the party wall line and how the new gable is built off it. Where the property is one of a pair, we draw the neighbouring roof too — an officer assessing the effect on the pair needs to see both.
The conversion needs a hip to work on, which limits it to semi-detached, detached and end-of-terrace houses — a mid-terrace has no hipped end to rebuild. On a semi, the new gable also has to be drawn against the neighbour's roof, since the pair was designed to read as one.
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.
What is a hip-to-gable-plus-dormer conversion?
Combining a hip-to-gable conversion with a rear dormer is one of the most effective ways to maximise a loft on a semi-detached or end-of-terrace house: the gable squares off the side of the roof while the dormer adds headroom over the rear slope and stairwell, together often creating close to a full-width habitable floor. We assess both elements together from the first survey — see our dormer loft conversion page for how the rear element is designed — rather than drawing a hip-to-gable in isolation and bolting on a dormer later. Because both elements are often permitted development on their own, the combined scheme frequently still fits within the same volume allowance, though we always check the running total before confirming the route.
