Dormer, hip-to-gable and mansard loft conversion drawings for Hove 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 Regency and early-Victorian stucco frontages of Brunswick and the seafront squares are protected in fine grain, down to render lines, railings and glazing, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837), Victorian (1837–1901), Edwardian (1901–1910) and interwar (1918–1939) housing stock sets the design brief on most streets.
Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which Brighton & Hove City Council needs a full application. Hove carries at least one Article 4 direction, and conservation areas including Old Hove, Brunswick Town and The Avenues remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Hove is determined against an 8-week statutory target.
Brunswick Town (Charles Busby's grand twin-terrace Regency estate off the seafront), The Avenues (wide Victorian streets of 1871–1901 villas between Church Road and the sea), Cliftonville (mid-Victorian Italianate villas and large Tudorbethan houses), Old Hove (the early stucco terraces around Brunswick and Adelaide Crescent), Poets' Corner (dense late-Victorian bay-fronted terraces north of Portland Road) and West Blatchington (interwar semi-detached suburbia on the downland fringe) — these are the Hove pockets our drawings cover most. Heritage designations here include Old Hove, Brunswick Town, The Avenues, Cliftonville, The Willett Estate and Sackville Gardens. Brighton & Hove City Council weighs each proposal against Brighton & Hove City Plan (Parts One 2016 and Two 2022) and the relevant SPDs, where seafront and set-piece square frontages attract the city's tightest design scrutiny, so alterations are kept behind the historic building line. Much of Brunswick Town, Old Hove and the Avenues is subdivided into flats and maisonettes, which carry no householder permitted-development rights of their own.. On roofs the borough is butterfly and valley roofs concealed behind the terrace parapets, mansard roofs on the taller stucco streets and hipped roofs on the interwar and villa stock, over Regency stucco terraces and set-piece squares, Victorian and Edwardian bay-fronted terraces, Italianate and Tudorbethan villas and interwar semi-detached houses.
Hove's roofs set the brief. The borough is built largely from Regency stucco terraces and set-piece squares, Victorian and Edwardian bay-fronted terraces, Italianate and Tudorbethan villas and interwar semi-detached houses, and its lofts sit under butterfly and valley roofs concealed behind the terrace parapets, mansard roofs on the taller stucco streets and hipped roofs on the interwar and villa stock — 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 Regency and early-Victorian stucco frontages of Brunswick and the seafront squares are protected in fine grain, down to render lines, railings and glazing, so we resolve it on the page rather than leave it for the case officer to raise.
Hove also carries protected streets — Old Hove, Brunswick Town, The Avenues, Cliftonville, The Willett Estate and Sackville Gardens among them. Hove sits inside Brighton & Hove's city-wide Article 4 direction for small houses in multiple occupation, and separate conservation-area Article 4s in the Brunswick Town and Avenues estates remove permitted-development rights for works — from windows to front boundary walls — that would be automatic on an unprotected street. We check your address against those designations before a line is drawn.
Many Hove 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. Brighton & Hove grants the large majority of householder applications city-wide, but in Hove the Regency conservation coverage and the protected seafront squares set close limits on what roofs, windows and front alterations can do. 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 Brunswick Town, The Avenues and Cliftonville, 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 butterfly and valley roofs concealed behind the terrace parapets, that is usually the most efficient use of the roof; where the stock is hipped roofs on the interwar and villa stock, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
Seafront and set-piece square frontages attract the city's tightest design scrutiny, so alterations are kept behind the historic building line. 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 Hove roofs come up most often:

The right loft in Hove 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 Old Hove and Brunswick Town 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 Hove 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 Hove the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Old Hove and Brunswick Town or on streets with an Article 4 direction. Brighton & Hove City Council is the decision-maker.
Generally no. In conservation areas including Old Hove and Brunswick Town, 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. Hove sits inside Brighton & Hove's city-wide Article 4 direction for small houses in multiple occupation, and separate conservation-area Article 4s in the Brunswick Town and Avenues estates remove permitted-development rights for works — from windows to front boundary walls — that would be automatic on an unprotected street. We check your exact address before drawing.
On butterfly and valley roofs concealed behind the terrace parapets, common across Hove, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is hipped roofs on the interwar and villa stock, 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 Hove 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.
