Full-plans building regulations drawings for Blockley — 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.
Cotswold District Council granted 92% of the householder planning decisions it made in its latest published year — 5 points above the 87% England-wide householder average. Blockley contains Aston Magna Conservation Area, Blockley Conservation Area, Ebrington Conservation Area conservation areas (Aston Magna Conservation Area designated 1989), 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) 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. Blockley carries at least one Article 4 direction, and conservation areas including Aston Magna Conservation Area, Blockley Conservation Area and Ebrington Conservation Area remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Blockley is determined against an 8-week statutory target.
Aston Magna (conservation area designated in 1989), Blockley (conservation area designated in 1976), Ebrington (conservation area designated in 1981), Hidcote Bartrim (conservation area designated in 1992), Hidcote Boyce (conservation area designated in 1981), Paxford (conservation area designated in 1981) and Ebrington (civil parish within Blockley) — these are the Blockley pockets our drawings cover most. Heritage designations here include Aston Magna Conservation Area, Blockley Conservation Area, Ebrington Conservation Area, Hidcote Bartrim Conservation Area, Hidcote Boyce Conservation Area and Paxford Conservation Area. Cotswold District Council weighs each proposal against Cotswold District Council's development plan and the design policies it applies to householder applications, where the 1,090 homes here are 33% pre-1900, 14% 1993-1999, 9% 2000-2008, 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 1990s building, over Victorian and earlier houses (33% of 1,090 homes), 1990s estate houses (14%) and 2000s houses and apartments (9%).
What is permitted in Blockley turns on designation first, so that is where we start: Aston Magna (conservation area designated in 1989), Blockley (conservation area designated in 1976), Ebrington (conservation area designated in 1981), Hidcote Bartrim (conservation area designated in 1992), Hidcote Boyce (conservation area designated in 1981) and Paxford (conservation area designated in 1981). Inside those boundaries permitted development is curtailed and Cotswold District 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, Blockley takes in Ebrington. Cotswold District Council has 22 recorded Article 4 directions, removing permitted development for rear and side extensions and roof enlargements such as dormers — check the address before assuming PD applies in Blockley.
On stock, Blockley is Victorian and earlier houses (33% of 1,090 homes), 1990s estate houses (14%) and 2000s houses and apartments (9%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and trussed-rafter roofs typical of 1990s building govern what a loft or rear projection can realistically be. Cotswold District Council decided 592 householder applications in the latest published year and granted 92%, with 53% issued inside the eight-week target. We draw to that record rather than to a national average.
The full build-period split for Blockley runs pre-1900 33% (360 homes), 1900-1918 7% (80 homes), 1919-1929 2% (20 homes), 1930-1939 7% (80 homes), 1945-1954 7% (80 homes), 1955-1964 3% (30 homes), 1965-1972 3% (30 homes), 1973-1982 4% (40 homes), 1983-1992 6% (70 homes), 1993-1999 14% (150 homes) and 2000-2008 9% (100 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.
Cotswold District Council also decides for Abbey, Bourton Vale, Bourton Village, Campden & Vale, Fairford North, Fosseridge, Kemble and Moreton East, so a decision in Blockley 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.
The Article 4 directions recorded for this council include Article 4 (2) Direction Avening, Article 4 (2) Direction Bibury, Article 4 (2) Direction Blockley and Article 4 (2) Direction Bourton-On-The-Water. Each removes a specific permitted-development right inside its own boundary, which is why the check is done on the address rather than on the town.

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 Blockley 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 Blockley's stock, which runs to Victorian and earlier houses (33% of 1,090 homes), 1990s estate houses (14%) and 2000s houses and apartments (9%), 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 Blockley regardless of planning designation, but in conservation areas such as Aston Magna Conservation Area, Blockley Conservation Area, Ebrington Conservation Area, Hidcote Bartrim Conservation Area, Hidcote Boyce Conservation Area and Paxford Conservation Area the two processes interact — insulation and window details often have to satisfy Part L and a planning condition at once. Cotswold District Council has 22 recorded Article 4 directions, removing permitted development for rear and side extensions and roof enlargements such as dormers — check the address before assuming PD applies in Blockley. We draw the construction details to reconcile both.
A full-plans set for Blockley 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 Cotswold District 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 Blockley projects clear planning first, so Cotswold District Council's live decision record below sets the context. Cotswold District Council granted 92% of its householder applications in the year to 31 March 2026, and Aston Magna Conservation Area shapes what is approved here. 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 Blockley we recommend the full-plans route — particularly on the borough's victorian and earlier houses (33% of 1,090 homes) and 1990s estate houses (14%), 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 Aston Magna, Blockley and Ebrington and the rest of Blockley. Where a project sits in a controlled setting — Blockley contains Aston Magna Conservation Area, Blockley Conservation Area, Ebrington Conservation Area conservation areas (Aston Magna Conservation Area designated 1989), so materials, fenestration and roof form are assessed against the appraisal — 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 Blockley neighbourhoods and property types where we prepare them most often:
Building regulations drawings for Aston Magna's conservation area designated in 1989 — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Blockley's conservation area designated in 1976 — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Ebrington's conservation area designated in 1981 — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Hidcote Bartrim's conservation area designated in 1992 — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Hidcote Boyce's conservation area designated in 1981 — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Paxford's conservation area designated in 1981 — 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 Blockley.
| Planning permission | Building regulations | |
|---|---|---|
| Question it answers | Should this be built here? | Is it built safely and efficiently? |
| Decided by | Cotswold District 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 Aston Magna Conservation Area and Blockley Conservation Area, a planning condition can dictate materials that the building regulations details must then also satisfy.
A fixed process built around how Blockley projects are approved and inspected — most construction sets are ready within seven days of survey.
Send us your Blockley postcode and scheme. We confirm whether you also need planning, which parts of the regulations apply, and whether Cotswold District 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 Cotswold District 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 Blockley 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 Blockley 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. Cotswold District Council is the decision-maker.
For anything structural in Blockley — 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 victorian and earlier houses (33% of 1,090 homes) 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 Cotswold District Council or an approved inspector signs off.
Yes. You can use Cotswold District 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 Blockley address specifically.
Solid-walled period houses — common across Blockley, including conservation areas such as Aston Magna Conservation Area and Blockley Conservation Area — 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. Cotswold District Council is the decision-maker.
We price each Blockley 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.
