Front-porch drawings for Kemp Town 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 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.
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. Kemp Town is largely Grade I and Grade II* Regency stucco terraces, bow-fronted seafront houses, 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 Kemp Town 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 Kemp Town's conservation areas — Kemp Town, East Cliff, Queen's Park and College among them — a porch is assessed on materials, roof form and how the door surround is treated. 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.

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. 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. 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 Kemp Town estate, East Cliff and Queen's Park, 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 grade i and grade ii* regency stucco terraces, 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 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 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 Kemp Town. 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 Kemp Town 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 Kemp Town 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 Kemp Town 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 Kemp Town 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 Kemp Town and East Cliff we confirm the position on your specific address first.
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 Kemp Town 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 Kemp Town address specifically. Brighton & Hove City Council is the decision-maker.
We quote each Kemp Town porch individually, because frontage type and boundary position vary house to house, and send a fixed, no-obligation quote within one working day. It covers the full drawing pack with free revisions until Brighton & Hove City Council approves. Call 020 7864 7245 to start.
