Front-porch drawings for Seven Dials homes — checked against the Class D permitted-development limits, drawn to Brighton & Hove City Council's frontage guidance, delivered in days and revised free until your decision, with a free approval-odds check 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 exceptionally complete stucco character of Montpelier and Clifton Hill is protected in fine grain, so render, glazing and roofline changes are tightly assessed, 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. Seven Dials carries at least one Article 4 direction, and conservation areas including Montpelier and Clifton Hill, West Hill and Prestonville remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Seven Dials is determined against an 8-week statutory target.
Montpelier (cohesive 1820s–1860s stucco terraces and villas west of the centre), Clifton Hill (the salubrious hillside estate of Regency and Victorian houses), West Hill (Victorian terraces that grew with the railway station below), Prestonville (tight Victorian terraces west of the main line), Seven Dials (the busy junction ringed by tall Victorian terraces) and Dyke Road fringe (larger detached and semi-detached Victorian villas) — these are the Seven Dials pockets our drawings cover most. Heritage designations here include Montpelier and Clifton Hill, West Hill, Prestonville and Stanford. Brighton & Hove City Council weighs each proposal against Brighton & Hove City Plan (Parts One 2016 and Two 2022) and the relevant SPDs, where basement and lightwell proposals on the hillside meet detailed structural and drainage policy on top of the householder tests. Much of Montpelier, West Hill and Prestonville is converted into flats and maisonettes, which carry no householder permitted-development rights.. On roofs the borough is parapet-hidden butterfly and valley roofs on the stucco terraces and pitched slate roofs on the Victorian streets, over Regency and early-Victorian stucco terraces and villas, later Victorian bay-fronted terraces and converted flats and maisonettes.
A porch is the smallest thing most people build and the most visible. It sits on the principal elevation, so Brighton & Hove City Council reads it against the rhythm of the whole street rather than against your own house alone. Seven Dials is largely Regency and early-Victorian stucco terraces and villas, later Victorian bay-fronted terraces and converted flats and maisonettes, and where a run of houses shares one front-door detail, a porch that ignores it stands out from fifty metres away.
The three Class D numbers do most of the work: 3 square metres of external floor area, 3 metres of height, and a 2-metre stand-off from any boundary that fronts a highway. That last one catches more porches in Seven Dials than the other two put together, because front gardens are shallow and the boundary is measured to the highway line, not to the kerb. We measure it on site and set the porch inside the limit, or we tell you honestly that it needs an application.
In Seven Dials's conservation areas — Montpelier and Clifton Hill, West Hill, Prestonville and Stanford among them — a porch is assessed on materials, roof form and how the door surround is treated. Seven Dials sits under the city-wide small-HMO Article 4 direction, while the Montpelier & Clifton Hill and West Hill conservation-area Article 4s remove permitted-development rights for external works to their stucco Regency and Victorian terraces.
Most modest porches are permitted development. You will need to apply to Brighton & Hove City Council if any of these apply:
We draw the porch to scale against the three Class D thresholds, show the highway boundary on the block plan, and detail the roof, door surround and threshold so Brighton & Hove City Council — and your neighbours — can see exactly what will be built.
Below is Brighton & Hove City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Brighton & Hove grants most householder schemes, yet across Seven Dials the dense stucco conservation coverage means heritage detailing, not principle, usually decides the outcome. A porch application turns on frontage design and the highway stand-off, so a pack that dimensions both is decided faster than a sketch.

Across Montpelier, Clifton Hill and West Hill, the porches that go through are the ones that borrow from the house: the same brick or render, a roof pitched to match, and a door and side-light proportioned to the original opening. On regency and early-victorian stucco terraces and villas, an open-sided canopy is often the better answer than an enclosed porch — it stays clear of the floor-area limit and leaves the frontage legible.
The exceptionally complete stucco character of Montpelier and Clifton Hill is protected in fine grain, so render, glazing and roofline changes are tightly assessed, which is exactly the sort of local reading a porch has to satisfy. Where the 2-metre highway stand-off cannot be met, we either recess the porch behind the building line or prepare a full householder application with an elevation that shows the porch in the context of its neighbours — the drawing that answers the officer's real question.
We draw porches on every street type in Seven Dials. A few of the areas where porch work comes up most often:

Class D sets three thresholds. This is how the common cases fall either side of them.
| Porch type | Permitted development? | What decides it | What Brighton & Hove City Council checks |
|---|---|---|---|
| Open canopy over the door | Usually yes — no enclosed floor area | Whether it is enclosed | Projection, materials, roof form |
| Enclosed porch under 3m² | Yes, if under 3m high and 2m from the highway boundary | External floor area | Highway stand-off, frontage design |
| Enclosed porch over 3m² | No — full application | External floor area | Bulk on the principal elevation |
| Porch in a conservation area | Only if it meets Class D and no Article 4 applies | Designation status | Materials, door detail, streetscape |
| Porch on a listed building | No — listed building consent required | Listing | Impact on special interest |
Thresholds from the Town and Country Planning (General Permitted Development) (England) Order 2015, Schedule 2, Part 1, Class D.
A fixed process built around how Brighton & Hove City Council validates and decides frontage work — most porch drawings are submission-ready within seven days of survey.
Send us your Seven Dials postcode. We confirm conservation, Article 4 and listing status, measure the front boundary against the 2-metre highway rule, and score your odds against live Brighton & Hove City Council decisions.
We measure the frontage, threshold level, door opening and the distance to the highway boundary — the four numbers a porch application stands or falls on.
Chartered designers develop the porch to your brief, either inside the Class D limits or as a full application drawn to Brighton & Hove City Council's design guidance, with materials and roof form matched to the house.
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.
Usually not, provided it meets all three Class D limits: no more than 3 square metres of external floor area, no more than 3 metres high, and no part within 2 metres of a boundary fronting a highway. Break any one and you need a householder application to Brighton & Hove City Council. On designated land, and on listed buildings, the position is different and we check it before drawing. This applies to your Seven Dials address specifically.
It is the external floor area — measured to the outside face of the porch walls, not the usable space inside. That catches people out, because a porch that feels small internally can exceed 3 square metres once the wall thickness is counted. We measure and dimension it on the plan so the figure is beyond argument at validation. This applies to your Seven Dials address specifically. Brighton & Hove City Council is the decision-maker.
No part of a permitted-development porch may be within 2 metres of any boundary of the property that fronts a highway. In Seven Dials this is the limit that most often pushes a porch into a full application, because front gardens are shallow. The measurement is to the boundary line, which is not always where the kerb or the fence sits — we establish it on survey. Brighton & Hove City Council is the decision-maker.
Yes, but the design bar is higher. Class D is not automatically removed in a conservation area, so a compliant porch can still be permitted development — however Brighton & Hove City Council will expect materials, roof pitch and door detail to respect the area's character, and an Article 4 direction can remove the right entirely. In Montpelier and Clifton Hill and West Hill we confirm the position on your specific address first. This applies to your Seven Dials address specifically.
A porch is exempt from most building regulations if it is under 30 square metres, at ground level, separated from the house by the existing external door, and any glazing and electrics meet Parts K, N and P. Remove the original front door and the porch becomes part of the heated envelope, at which point insulation and Part L apply. We flag which side of that line your design falls on. This applies to your Seven Dials address specifically. Brighton & Hove City Council is the decision-maker.
A householder application runs to an eight-week statutory target, and a lawful development certificate to the same. The realistic risk is not the decision but validation — an incomplete pack is returned rather than determined. We prepare the submission validation-complete and handle officer queries so the timetable holds. This applies to your Seven Dials address specifically. Brighton & Hove City Council is the decision-maker.
