Full-plans building regulations drawings for Ashford — 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.
Ashford Borough Council granted 92% of the householder planning decisions it made in its latest published year — 5 points above the 87% England-wide householder average. Ashford contains Aldington - Church Area, Aldington - Clap Hill, Appledore conservation areas (Aldington - Church Area designated 1996), 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) and postwar (1945–1970) housing stock sets the design brief on most streets.
The permitted-development ceilings are fixed: 40m³ of new roof volume for a terraced loft and 50m³ for a semi or detached house under Class B, plus a 3m single-storey rear extension on a terrace or 4m on a detached house under Class A. Ashford carries at least one Article 4 direction, and conservation areas including Aldington - Church Area, Aldington - Clap Hill and Appledore remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Ashford is determined against an 8-week statutory target.
Aldington - Church Area (conservation area designated in 1996), Aldington - Clap Hill (conservation area designated in 1996), Appledore (conservation area designated in 1987), Ashford - Lacton Green (conservation area designated in 1991), Bethersden (conservation area designated in 1996), Bilsington (conservation area designated in 1996), Brabourne (conservation area designated in 1996), Chilham (conservation area designated in 1996), Bircholt (ward of Ashford), Downs North (ward of Ashford), Isle of Oxney (ward of Ashford), Kennington (ward of Ashford), Saxon Shore (ward of Ashford), Tenterden South (ward of Ashford), Tenterden St Michael's (ward of Ashford) and Upper Weald (ward of Ashford) — these are the Ashford pockets our drawings cover most. Heritage designations here include Aldington - Church Area, Aldington - Clap Hill, Appledore, Ashford - Lacton Green, Bethersden, Bilsington, Brabourne and Chilham. Ashford Borough Council weighs each proposal against Ashford Borough Council's adopted local plan and its householder design guidance, where the 19,960 homes here are 21% pre-1900, 7% 1955-1964, 6% 1965-1972, 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 shallow gabled roofs typical of that period's building, over Victorian and earlier houses (21% of 19,960 homes), late-1950s and early-1960s houses (7%) and late-1960s and early-1970s houses (6%).
Before anything is drawn we check your address against the designations that apply in Ashford: Aldington - Church Area (conservation area designated in 1996), Aldington - Clap Hill (conservation area designated in 1996), Appledore (conservation area designated in 1987), Ashford - Lacton Green (conservation area designated in 1991), Bethersden (conservation area designated in 1996), Bilsington (conservation area designated in 1996), Brabourne (conservation area designated in 1996) and Chilham (conservation area designated in 1996). Inside those boundaries permitted development is curtailed and Ashford Borough 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, Ashford takes in Bircholt, Downs North, Isle of Oxney, Kennington, Saxon Shore, Tenterden South, Tenterden St Michael's and Upper Weald. Ashford Borough Council has 73 recorded Article 4 directions — check the address before assuming PD applies in the district.
On stock, Ashford is Victorian and earlier houses (21% of 19,960 homes), late-1950s and early-1960s houses (7%) and late-1960s and early-1970s houses (6%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow gabled roofs typical of that period's building govern what a loft or rear projection can realistically be. Ashford Borough Council decided 453 householder applications in the latest published year and granted 92%, with 75% issued inside the eight-week target. That decision record, not a national figure, is what we design to.
The full build-period split for Ashford runs pre-1900 3% (190 homes), 1900-1918 0% (30 homes), 1919-1929 0% (10 homes), 1930-1939 6% (350 homes), 1945-1954 3% (170 homes), 1955-1964 30% (1,850 homes), 1965-1972 33% (1,990 homes), 1973-1982 4% (260 homes), 1983-1992 5% (310 homes), 1993-1999 4% (220 homes) and 2000-2008 3% (170 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.
Ashford Borough Council also decides for Bircholt, Downs North, Isle of Oxney, Kennington, Saxon Shore, Tenterden South, Tenterden St Michael's and Upper Weald, so a decision in Ashford 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 1 - Caravan, 2 3 - agriculture, 4 - forestry, 1 - Gate, fence, wall, 2 - Use of land, 1 - Use of land, 2 3 - Agricultural, 4 - Forestry and 1 - gate, fence, 2 - use of land. 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 Ashford 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 Ashford's stock, which runs to Victorian and earlier houses (21% of 19,960 homes), late-1950s and early-1960s houses (7%) and late-1960s and early-1970s houses (6%), 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 Ashford regardless of planning designation, but in conservation areas such as Aldington - Church Area, Aldington - Clap Hill, Appledore, Ashford - Lacton Green, Bethersden, Bilsington, Brabourne and Chilham the two processes interact — insulation and window details often have to satisfy Part L and a planning condition at once. Ashford Borough Council has 73 recorded Article 4 directions — check the address before assuming PD applies in the district. We draw the construction details to reconcile both.
A full-plans set for Ashford 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 Ashford Borough 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 Ashford projects clear planning first, so Ashford Borough Council's live decision record below sets the context. Ashford Borough Council granted 92% of 453 householder decisions in the year to 31 March 2026, 75% of them inside eight weeks. 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 Ashford we recommend the full-plans route — particularly on the borough's victorian and earlier houses (21% of 19,960 homes) and late-1950s and early-1960s houses (7%), 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 Aldington - Church Area, Aldington - Clap Hill and Appledore and the rest of Ashford. Where a project sits in a controlled setting — Ashford contains Aldington - Church Area, Aldington - Clap Hill, Appledore conservation areas (Aldington - Church Area designated 1996), 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 Ashford neighbourhoods and property types where we prepare them most often:
Building regulations drawings for Aldington - Church Area's conservation area designated in 1996 — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Aldington - Clap Hill's conservation area designated in 1996 — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Appledore's conservation area designated in 1987 — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Ashford - Lacton Green's conservation area designated in 1991 — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Bethersden's conservation area designated in 1996 — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Bilsington's conservation area designated in 1996 — 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 Ashford.
| Planning permission | Building regulations | |
|---|---|---|
| Question it answers | Should this be built here? | Is it built safely and efficiently? |
| Decided by | Ashford Borough 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 Aldington - Church Area and Aldington - Clap Hill, a planning condition can dictate materials that the building regulations details must then also satisfy.
A fixed process built around how Ashford projects are approved and inspected — most construction sets are ready within seven days of survey.
Send us your Ashford postcode and scheme. We confirm whether you also need planning, which parts of the regulations apply, and whether Ashford Borough 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 Ashford Borough 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 Ashford 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 Ashford 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. Ashford Borough Council is the decision-maker.
For anything structural in Ashford — 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 (21% of 19,960 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 Ashford Borough Council or an approved inspector signs off.
Yes. You can use Ashford Borough 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 Ashford, including conservation areas such as Aldington - Church Area and Aldington - Clap 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. Ashford Borough Council is the decision-maker.
We price each Ashford 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.
