Dormer, hip-to-gable and mansard loft conversion drawings for Kemp Town homes — prepared to Brighton & Hove City Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
Brighton & Hove City Council granted 89% of the householder planning decisions it made in its latest published year — 2 points above the 87% England-wide householder average. The Kemp Town estate holds one of the densest concentrations of Grade I and Grade II* listing in the city, so alterations are assessed against the original architectural set piece, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837) and Victorian (1837–1901) housing stock sets the design brief on most streets.
Before permission is required, Class B allows 40m³ of added loft volume on a terrace and 50m³ on a semi or detached house, and Class A allows a 3m single-storey rear extension on a terrace or 4m on a detached house. Kemp Town carries at least one Article 4 direction, and conservation areas including Kemp Town, East Cliff and Queen's Park remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Kemp Town is determined against an 8-week statutory target.
Kemp Town estate (Busby and Wilds' 1820s set piece of Sussex Square and Lewes Crescent), East Cliff (bow-fronted Regency terraces stepping up from Marine Parade), Queen's Park (Victorian terraces and villas around the park bowl), College (planned Victorian streets near Brighton College), Kemptown Village (the compact St George's Road high-street terraces) and Whitehawk fringe (later housing climbing the eastern downland slope) — these are the Kemp Town pockets our drawings cover most. Heritage designations here include Kemp Town, East Cliff, Queen's Park and College. Brighton & Hove City Council weighs each proposal against Brighton & Hove City Plan (Parts One 2016 and Two 2022) and the relevant SPDs, where basement, lightwell and seafront-frontage proposals meet detailed structural and heritage tests before the usual householder considerations. Large tracts of the Regency terraces are long since converted into flats and maisonettes, which hold no householder permitted-development rights.. On roofs the borough is parapet-hidden flat and shallow leaded roofs on the Regency estate, butterfly roofs behind the terrace fronts and pitched slate roofs on the Victorian streets, over Grade I and Grade II* Regency stucco terraces, bow-fronted seafront houses, Victorian bay-fronted terraces and converted flats and maisonettes.
Kemp Town's roofs set the brief. The borough is built largely from Grade I and Grade II* Regency stucco terraces, bow-fronted seafront houses, Victorian bay-fronted terraces and converted flats and maisonettes, and its lofts sit under parapet-hidden flat and shallow leaded roofs on the Regency estate, butterfly roofs behind the terrace fronts and pitched slate roofs on the Victorian streets — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Brighton & Hove City Council assesses loft proposals against Brighton & Hove City Plan (Parts One 2016 and Two 2022) and the relevant SPDs, and its case officers read each roof against the pair next door and the wider street before they read the plans.
That makes drawing quality decisive. We measure ridge and eaves heights, roof pitch and the existing stair, calculate the added volume against the permitted-development limits exactly, and show the workings on the drawings so Brighton & Hove City Council can verify them. The Kemp Town estate holds one of the densest concentrations of Grade I and Grade II* listing in the city, so alterations are assessed against the original architectural set piece, so we resolve it on the page rather than leave it for the case officer to raise.
Kemp Town also carries protected streets — Kemp Town, East Cliff, Queen's Park and College among them. Kemp Town falls under the city-wide Article 4 direction removing permitted-development rights for small HMOs, and the Kemp Town and East Cliff conservation-area controls pull most external alterations to the listed Regency terraces into the application system. We check your address against those designations before a line is drawn.
Many Kemp Town loft conversions proceed without planning permission — a rear dormer within the permitted-development volume limits (40 cubic metres on a terrace, 50 on a semi or detached house) is usually lawful. You will normally need a full application to Brighton & Hove City Council if any of these apply:
We draw the roof line, the ridge height and the neighbour's daylight on the page — the relationships Brighton & Hove City Council's officers check first — and submit a validation-complete pack, whether that is a lawful development certificate or a full householder application.
Below is Brighton & Hove City Council's real householder decision record, pulled from official planning statistics and updated as new data lands. The council approves most householder schemes across the city, yet in Kemp Town the concentration of high-grade listed terraces means heritage impact, not principle, decides how far a project can go. Professionally prepared loft drawings anticipate those pressure points before submission, which is why complete, policy-literate packs are decided faster and refused less often than DIY applications.

Across Kemp Town estate, East Cliff and Queen's Park, the recurring loft is the rear dormer — a box across the back roof slope that turns a cramped attic into a full-height double bedroom and en-suite. On parapet-hidden flat and shallow leaded roofs on the Regency estate, that is usually the most efficient use of the roof; where the stock is pitched slate roofs on the Victorian streets, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
Basement, lightwell and seafront-frontage proposals meet detailed structural and heritage tests before the usual householder considerations. We draw the dormer inside the volume allowance, keep the flat-roof build-up below the ridge, and set the face back from the eaves as the rules require — so the pack answers Brighton & Hove City Council's questions before they are asked. Where permitted-development rights are exhausted or removed, we prepare a householder application composed to the borough's roof-alteration guidance instead.
We draw loft conversions on every street in the borough. A few of the neighbourhoods where Kemp Town roofs come up most often:

The right loft in Kemp Town depends on your roof. This is how the main types compare on planning route and the space they add.
| Loft type | Permitted development? | Space & headroom | What Brighton & Hove City Council checks |
|---|---|---|---|
| Rear dormer | Usually yes, within volume limits | Full-height double room at the back | Volume, set-back from eaves, ridge height |
| Hip-to-gable | No — full application | Extends the whole side of the roof | Roof bulk and the symmetry of the pair |
| Mansard | No — full application | Maximum floor area across the roof | Street character, especially in conservation areas |
| Rooflights only | Usually yes (Class C) | Light and headroom, no extra footprint | Whether rooflights sit within the existing slope |
Route depends on your street — conservation areas such as Kemp Town and East Cliff and Article 4 directions can remove permitted-development rights.
A fixed process built around how Brighton & Hove City Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your Kemp Town postcode and roof type. We confirm your conservation and Article 4 status, how much permitted-development volume you have left, and score your odds against live Brighton & Hove City Council decisions.
We measure ridge and eaves heights, roof pitch, joist levels and the existing stair — the numbers the volume calculation and head heights depend on.
Chartered designers develop the dormer, hip-to-gable or mansard to your brief, drawn inside the Class B limits or to Brighton & Hove City Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Brighton & Hove City Council issues its decision.
Often not. A rear dormer within 40 cubic metres on a terrace, or 50 on a semi-detached or detached house, set back from the eaves and no higher than the ridge, is usually permitted development. In Kemp Town the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Kemp Town and East Cliff or on streets with an Article 4 direction. Brighton & Hove City Council is the decision-maker.
Generally no. In conservation areas including Kemp Town and East Cliff, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Brighton & Hove City Council. Kemp Town falls under the city-wide Article 4 direction removing permitted-development rights for small HMOs, and the Kemp Town and East Cliff conservation-area controls pull most external alterations to the listed Regency terraces into the application system. We check your exact address before drawing.
On parapet-hidden flat and shallow leaded roofs on the Regency estate, common across Kemp Town, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is pitched slate roofs on the Victorian streets, a hip-to-gable followed by a rear dormer gains far more usable space but needs planning permission. Our survey confirms which your roof supports before we draw. Brighton & Hove City Council is the decision-maker.
A householder planning application in Kemp Town runs to a statutory eight-week target, and a lawful development certificate to eight weeks as well, though validation can add time if the pack is incomplete. We submit validation-complete drawings and manage case-officer queries to keep the decision on track. Brighton & Hove City Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Brighton & Hove City Council is council-stamped proof of that — worth having, because every buyer's solicitor will ask for it when you sell. We prepare and submit the certificate application with the same drawing pack. This applies to your Kemp Town address specifically.
