Dormer, hip-to-gable and mansard loft conversion drawings for Hastings homes — prepared to Hastings Borough Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
Hastings Borough Council granted 90% of the householder planning decisions it made in its latest published year — 3 points above the 87% England-wide householder average. Hastings contains Burtons', St Leonards, Cornwallis Gardens, Hastings, Eversfield Place, St Leonards conservation areas (Old Town, Hastings designated 1968), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) and Edwardian (1901–1910) 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. In conservation areas such as Burtons', St Leonards, Cornwallis Gardens, Hastings and Eversfield Place, St Leonards those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Hastings is determined against an 8-week statutory target.
Burtons', St Leonards (designated conservation area), Cornwallis Gardens, Hastings (designated conservation area), Eversfield Place, St Leonards (designated conservation area), Grosvenor Gardens (designated conservation area), Hastings Town Centre (designated conservation area), King's Road, St Leonards (designated conservation area), Magdalen Road, St Leonards (designated conservation area), Old Town, Hastings (conservation area designated in 1968), Castle (ward of Hastings), Central St Leonards (ward of Hastings), Maze Hill (ward of Hastings) and Old Hastings (ward of Hastings) — these are the Hastings pockets our drawings cover most. Heritage designations here include Burtons', St Leonards, Cornwallis Gardens, Hastings, Eversfield Place, St Leonards, Grosvenor Gardens, Hastings Town Centre, King's Road, St Leonards, Magdalen Road, St Leonards and Old Town, Hastings. Hastings Borough Council weighs each proposal against the adopted Hastings local plan and Hastings Borough Council's design guidance for householder work, where the 14,430 homes here are 63% pre-1900, 6% 1983-1992, 4% 1900-1918, which is what sets the realistic roof and rear-projection options. On roofs the borough is steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and trussed-rafter roofs typical of 1980s building, over Victorian and earlier houses (63% of 14,430 homes), 1980s estate houses (6%) and Edwardian houses (4%).
What is permitted in Hastings turns on designation first, so that is where we start: Burtons', St Leonards (designated conservation area), Cornwallis Gardens, Hastings (designated conservation area), Eversfield Place, St Leonards (designated conservation area), Grosvenor Gardens (designated conservation area), Hastings Town Centre (designated conservation area), King's Road, St Leonards (designated conservation area), Magdalen Road, St Leonards (designated conservation area) and Old Town, Hastings (conservation area designated in 1968). Inside those boundaries permitted development is curtailed and Hastings Borough Council assesses materials, window detail and roof form against the area's own appraisal, so a scheme that would be waved through two streets away can need a full application here.
Beyond the designated areas, Hastings takes in Castle, Central St Leonards, Maze Hill and Old Hastings. No Article 4 direction is recorded for Hastings Borough Council, but the district's 8 conservation areas still limit permitted development on those streets.
On stock, Hastings is Victorian and earlier houses (63% of 14,430 homes), 1980s estate houses (6%) and Edwardian houses (4%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and trussed-rafter roofs typical of 1980s building govern what a loft or rear projection can realistically be. Hastings Borough Council decided 109 householder applications in the latest published year and granted 90%, with 67% issued inside the eight-week target. We draw to that record rather than to a national average.
The full build-period split for Hastings runs pre-1900 3% (190 homes), 1900-1918 0% (30 homes), 1919-1929 0% (10 homes), 1930-1939 6% (350 homes), 1945-1954 3% (170 homes), 1955-1964 30% (1,850 homes), 1965-1972 33% (1,990 homes), 1973-1982 4% (260 homes), 1983-1992 5% (310 homes), 1993-1999 4% (220 homes) and 2000-2008 3% (170 homes). That distribution is why pre-1900 detailing dominates the drawings here, and it is measured from council-tax records rather than assumed from the street name.
Hastings Borough Council also decides for Castle, Central St Leonards, Maze Hill and Old Hastings, so a decision in Hastings sits inside a wider pattern of decisions we track across the same authority — useful when an officer cites a precedent from the next area over.

Hastings's roofs set the brief. The borough is built largely from Victorian and earlier houses (63% of 14,430 homes), 1980s estate houses (6%) and Edwardian houses (4%), and its lofts sit under steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and trussed-rafter roofs typical of 1980s building — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Hastings Borough Council assesses loft proposals against the adopted Hastings local plan and Hastings Borough Council's design guidance for householder work, 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 Hastings Borough Council can verify them. Hastings contains Burtons', St Leonards, Cornwallis Gardens, Hastings, Eversfield Place, St Leonards conservation areas (Old Town, Hastings designated 1968), so materials, fenestration and roof form are assessed against the appraisal, so we resolve it on the page rather than leave it for the case officer to raise.
Hastings also carries protected streets — Burtons', St Leonards, Cornwallis Gardens, Hastings, Eversfield Place, St Leonards, Grosvenor Gardens, Hastings Town Centre, King's Road, St Leonards, Magdalen Road, St Leonards and Old Town, Hastings among them. No Article 4 direction is recorded for Hastings Borough Council, but the district's 8 conservation areas still limit permitted development on those streets. We check your address against those designations before a line is drawn.
Many Hastings 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 Hastings Borough Council if any of these apply:
We draw the roof line, the ridge height and the neighbour's daylight on the page — the relationships Hastings Borough 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 Hastings Borough Council's real householder decision record, pulled from official planning statistics and updated as new data lands. Hastings Borough Council granted 90% of 109 householder decisions in the year to 31 March 2026, 67% of them inside eight weeks. 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 Burtons', St Leonards, Cornwallis Gardens, Hastings and Eversfield Place, St Leonards, 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 steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, that is usually the most efficient use of the roof; where the stock is trussed-rafter roofs typical of 1980s building, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
The 14,430 homes here are 63% pre-1900, 6% 1983-1992, 4% 1900-1918, which is what sets the realistic roof and rear-projection options. 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 Hastings Borough 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 Hastings roofs come up most often:

The right loft in Hastings 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 Hastings Borough 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 Burtons', St Leonards and Cornwallis Gardens, Hastings and Article 4 directions can remove permitted-development rights.
A fixed process built around how Hastings Borough Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your Hastings 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 Hastings Borough 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 Hastings Borough Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Hastings Borough 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 Hastings the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Burtons', St Leonards and Cornwallis Gardens, Hastings or on streets with an Article 4 direction. Hastings Borough Council is the decision-maker.
Generally no. In conservation areas including Burtons', St Leonards and Cornwallis Gardens, Hastings, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Hastings Borough Council. No Article 4 direction is recorded for Hastings Borough Council, but the district's 8 conservation areas still limit permitted development on those streets. We check your exact address before drawing.
On steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, common across Hastings, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is trussed-rafter roofs typical of 1980s building, 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. Hastings Borough Council is the decision-maker.
A householder planning application in Hastings 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. Hastings Borough Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Hastings Borough 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.
