Full-plans building regulations drawings for Seven Dials — the technical construction set covering structure, fire safety, insulation and Part L, drawn to satisfy building control so your builder can price and build with certainty, delivered in days and revised free until sign-off, with a free project 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.
Planning permission decides whether you can build; the Building Regulations decide that what you build is safe, warm and sound. They are two separate approvals, run by different bodies, and a Seven Dials project usually needs both. The building regulations set is the technical layer beneath the planning drawings — construction sections, structural details, insulation build-ups and fire-safety provisions that a builder works from and a building control surveyor checks against the approved documents.
In practice that means Part A structure — beam and foundation details with the structural calculations behind them; Part B fire — escape, protected routes and, in a loft, a fire door and mains-linked alarms; Part L conservation of fuel and power — U-values, insulation and airtightness; plus drainage, ventilation and stairs. On Seven Dials's stock, which runs to Regency and early-Victorian stucco terraces and villas, later Victorian bay-fronted terraces and converted flats and maisonettes, the recurring challenge is meeting Part L in solid-walled period houses without ruining the room, and we detail the insulation to hit the numbers with the least intrusion.
Building control applies everywhere in Seven Dials regardless of planning designation, but in conservation areas such as Montpelier and Clifton Hill, West Hill, Prestonville and Stanford the two processes interact — insulation and window details often have to satisfy Part L and a planning condition at once. 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. We draw the construction details to reconcile both.

A full-plans set for Seven Dials building control is checked against the Approved Documents. A typical extension or loft set covers each of these:
We produce the full-plans construction set — structure, fire, thermal and drainage details with the structural calculations — and submit it to your chosen building control body, whether that is Brighton & Hove City Council's own team or an approved inspector, so problems are settled on paper before they cost money on site.
Building control is a separate approval, but most Seven Dials projects clear planning first, so Brighton & Hove City Council's live decision record below sets the context. Brighton & Hove grants most householder schemes, yet across Seven Dials the dense stucco conservation coverage means heritage detailing, not principle, usually decides the outcome. We handle both stages, so the construction drawings follow through seamlessly once permission is granted.

There are two ways to get building control approval, and for anything structural in Seven Dials we recommend the full-plans route — particularly on the borough's regency and early-victorian stucco terraces and villas and later victorian bay-fronted terraces, where opening up an old structure tends to reveal surprises. A building notice lets work start with no approved drawings — cheaper up front, but the surveyor rules on compliance as the build proceeds, so a wrong detail is discovered mid-work and rebuilt at your cost. Full plans get the whole set checked and approved before a brick moves, which is what banks, warranty providers and future buyers want to see.
Full plans also protect the project commercially. With approved construction drawings your builder prices exact quantities rather than guessing, and there is a completion certificate at the end — the document a solicitor asks for when you sell across Montpelier, Clifton Hill and West Hill and the rest of Seven Dials. Where a project sits in a controlled setting — the exceptionally complete stucco character of Montpelier and Clifton Hill is protected in fine grain, so render, glazing and roofline changes are tightly assessed — the construction details also have to respect what planning has conditioned, and we draw the full set and manage the building control submission to reconcile both.

Every structural project needs building regulations drawings whatever the planning position. A few of the Seven Dials neighbourhoods and property types where we prepare them most often:
Building regulations drawings for Montpelier's cohesive 1820s–1860s stucco terraces and villas west of the centre — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Clifton Hill's the salubrious hillside estate of Regency and Victorian houses — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for West Hill's Victorian terraces that grew with the railway station below — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Prestonville's tight Victorian terraces west of the main line — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Seven Dials's the busy junction ringed by tall Victorian terraces — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Dyke Road fringe's larger detached and semi-detached Victorian villas — structure, fire and Part L detailed for building control sign-off.
They are different approvals and most projects need both. This is how they split in Seven Dials.
| Planning permission | Building regulations | |
|---|---|---|
| Question it answers | Should this be built here? | Is it built safely and efficiently? |
| Decided by | Brighton & Hove City Council planning | Building control body or approved inspector |
| Main drawings | Location, block, proposed plans & elevations | Structural, fire, thermal & construction details |
| Needed for permitted development? | No — a certificate is optional | Yes — always, before work starts |
In conservation areas such as Montpelier and Clifton Hill and West Hill, a planning condition can dictate materials that the building regulations details must then also satisfy.
A fixed process built around how Seven Dials projects are approved and inspected — most construction sets are ready within seven days of survey.
Send us your Seven Dials postcode and scheme. We confirm whether you also need planning, which parts of the regulations apply, and whether Brighton & Hove City Council building control or an approved inspector suits the job.
We measure the existing structure so the construction details, spans and junctions are drawn to the real building rather than an assumption — the base sound structural calculations depend on.
Chartered designers and engineers produce the full-plans set — structure, fire, Part L thermal, drainage and details — with the structural calculations that support every beam and foundation.
We submit the full-plans application to your building control body, resolve any queries before work starts, and revise the drawings free until the set is approved and the work signed off.
They are two separate approvals. Planning permission, decided by Brighton & Hove City Council, answers whether a scheme should be built at all — its size, look and impact on neighbours. Building regulations, checked by a building control body, answer whether it is built safely and efficiently — structure, fire, insulation and drainage. A Seven Dials project usually needs both, and even permitted-development work that skips planning still needs building control sign-off.
Yes — planning permission is not building control approval. The planning drawings show what the building looks like; building regulations drawings show how it is constructed, and no structural work in Seven Dials can lawfully complete without a building control sign-off. The two sets are drawn together but approved by different bodies, so having one never removes the need for the other. Brighton & Hove City Council is the decision-maker.
For anything structural in Seven Dials — a loft, an extension or removing a wall — we recommend full plans. The whole construction set is checked and approved before work starts, so a non-compliant detail is caught on paper rather than rebuilt on site. On the borough's regency and early-victorian stucco terraces and villas that certainty matters, and a building notice — which lets a surveyor judge compliance as work proceeds — risks costly rework. Banks and warranty providers also prefer the approved full-plans set that Brighton & Hove City Council or an approved inspector signs off.
Yes. You can use Brighton & Hove City Council's building control team or an independent approved inspector — both enforce the same regulations, so it comes down to price, availability and continuity. We draw the full-plans set to the same standard either way and submit it to whichever body you choose, then manage the queries and inspections through to the completion certificate. This applies to your Seven Dials address specifically.
Solid-walled period houses — common across Seven Dials, including conservation areas such as Montpelier and Clifton Hill and West Hill — are the hardest to bring up to Part L without losing room or altering the fabric. We detail the insulation to hit the required U-values with the least intrusion, using internal or roof-level build-ups and, where a planning condition protects the exterior, methods that satisfy both the energy standard and the heritage requirement at once. Brighton & Hove City Council is the decision-maker.
We price each Seven Dials job individually, because the structural content and the size of the construction set vary from a single beam to a whole-house refurbishment, and send a fixed, no-obligation quote within one working day. It covers the full-plans drawings and structural calculations with free revisions until sign-off. The building control body's own fee is separate. Call 020 7864 7245 to start.
