Full-plans building regulations drawings for Camden — 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.
Camden Council granted 88% of the householder planning decisions it made in its latest published year — 1 point above the 87% England-wide householder average. The council runs one of London's strictest basement regimes, capping depth and demanding a Basement Impact Assessment, 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.
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 Camden Council needs a full application. Camden carries at least one Article 4 direction, and conservation areas including Hampstead, Fitzroy Square and Bloomsbury remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Camden is determined against an 8-week statutory target.
Hampstead (Georgian and Victorian houses inside a tightly protected conservation area), Belsize Park (grand Victorian villas and red-brick mansion blocks), Camden Town (dense Victorian terraces around the market), Primrose Hill (pastel-painted Victorian terraces beside Regent's Park), Kentish Town (Victorian terraces and converted flats) and Bloomsbury (Georgian squares and formal terraces) — these are the Camden pockets our drawings cover most. Heritage designations here include Hampstead, Fitzroy Square, Bloomsbury, Camden Town and Primrose Hill. Camden Council weighs each proposal against Camden Local Plan and the Camden Planning Guidance (CPG) on home improvements, where mansard and roof additions in conservation areas are measured against the terrace's original roofline and rhythm. Purpose-built mansion flats and converted terraces are widespread, and flats and maisonettes carry no householder permitted-development rights.. On roofs the borough is London butterfly / valley roofs behind parapets and mansard roofs on the taller terraces, over Georgian and Victorian terraces, purpose-built mansion flats and converted period flats.
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 Camden 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 Camden's stock, which runs to Georgian and Victorian terraces, purpose-built mansion flats and converted period flats, 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 Camden regardless of planning designation, but in conservation areas such as Hampstead, Fitzroy Square, Bloomsbury, Camden Town and Primrose Hill the two processes interact — insulation and window details often have to satisfy Part L and a planning condition at once. Much of Camden — the Hampstead and Fitzroy Square conservation areas among them — sits under Article 4 directions that strip out permitted-development rights, and the borough's basement rules pile on a further layer of control. We draw the construction details to reconcile both.

A full-plans set for Camden 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 Camden 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 Camden projects clear planning first, so Camden Council's live decision record below sets the context. Camden approves the large majority of householder applications, though its basement policy and dense conservation coverage are the decisive constraints on many schemes. 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 Camden we recommend the full-plans route — particularly on the borough's georgian and victorian terraces and purpose-built mansion flats, 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 Hampstead, Belsize Park and Camden Town and the rest of Camden. Where a project sits in a controlled setting — the council runs one of London's strictest basement regimes, capping depth and demanding a Basement Impact Assessment — 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 Camden neighbourhoods and property types where we prepare them most often:
Building regulations drawings for Hampstead's Georgian and Victorian houses inside a tightly protected conservation area — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Belsize Park's grand Victorian villas and red-brick mansion blocks — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Camden Town's dense Victorian terraces around the market — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Primrose Hill's pastel-painted Victorian terraces beside Regent's Park — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Kentish Town's Victorian terraces and converted flats — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Bloomsbury's Georgian squares and formal terraces — 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 Camden.
| Planning permission | Building regulations | |
|---|---|---|
| Question it answers | Should this be built here? | Is it built safely and efficiently? |
| Decided by | Camden 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 Hampstead and Fitzroy Square, a planning condition can dictate materials that the building regulations details must then also satisfy.
A fixed process built around how Camden projects are approved and inspected — most construction sets are ready within seven days of survey.
Send us your Camden postcode and scheme. We confirm whether you also need planning, which parts of the regulations apply, and whether Camden 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 Camden 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 Camden 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 Camden 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. Camden Council is the decision-maker.
For anything structural in Camden — 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 georgian and victorian terraces 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 Camden Council or an approved inspector signs off.
Yes. You can use Camden 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.
Solid-walled period houses — common across Camden, including conservation areas such as Hampstead and Fitzroy Square — 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. Camden Council is the decision-maker.
We price each Camden 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.
