Full-plans building regulations drawings for Mark Hall — 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.
Harlow District Council granted 79% of the householder planning decisions it made in its latest published year — 8 points below the 87% England-wide householder average. Mark Hall contains Harlow Mill and Old Road North, Mark Hall North conservation areas (Harlow Mill and Old Road North designated 1998), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant 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. Mark Hall carries at least one Article 4 direction, and conservation areas including Harlow Mill and Old Road North and Mark Hall North remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Mark Hall is determined against an 8-week statutory target.
Harlow Mill and Old Road North (conservation area designated in 1998) and Mark Hall North (conservation area designated in 1987) — these are the Mark Hall pockets our drawings cover most. Heritage designations here include Harlow Mill and Old Road North and Mark Hall North. Harlow District Council weighs each proposal against the adopted Harlow local plan and Harlow District Council's design guidance for householder work, where the 3,380 homes here are 81% 1945-1954, 7% 1983-1992, 3% 2000-2008, which is what sets the realistic roof and rear-projection options. On roofs the borough is simple gabled and hipped roofs typical of early postwar building and trussed-rafter roofs typical of 1980s building, over early postwar houses (81% of 3,380 homes), 1980s estate houses (7%) and 2000s houses and apartments (3%).
Before anything is drawn we check your address against the designations that apply in Mark Hall: Harlow Mill and Old Road North (conservation area designated in 1998) and Mark Hall North (conservation area designated in 1987). Inside those boundaries permitted development is curtailed and Harlow 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.
Harlow District Council has 14 recorded Article 4 directions, removing permitted development for rear and side extensions and other roof alterations, including rooflights — check the address before assuming PD applies in Mark Hall.
On stock, Mark Hall is early postwar houses (81% of 3,380 homes), 1980s estate houses (7%) and 2000s houses and apartments (3%) — which is why simple gabled and hipped roofs typical of early postwar building and trussed-rafter roofs typical of 1980s building govern what a loft or rear projection can realistically be. Harlow District Council decided 149 householder applications in the latest published year and granted 79%, with 67% issued inside the eight-week target. That decision record, not a national figure, is what we design to.
The full build-period split for Mark Hall runs pre-1900 0% (10 homes), 1945-1954 81% (2,750 homes), 1955-1964 2% (60 homes), 1965-1972 0% (10 homes), 1973-1982 2% (70 homes), 1983-1992 7% (220 homes), 1993-1999 1% (30 homes) and 2000-2008 3% (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.
Harlow District Council also decides for Bush Fair and Old Harlow, so a decision in Mark Hall 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 to 56 Morley Grove, 57 to 99 Morley Grove, Churchgate Street and Field House and Goodman House (Burnt Mill Industrial Estate). 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 Mark Hall 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 Mark Hall's stock, which runs to early postwar houses (81% of 3,380 homes), 1980s estate houses (7%) and 2000s houses and apartments (3%), 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 Mark Hall regardless of planning designation, but in conservation areas such as Harlow Mill and Old Road North and Mark Hall North the two processes interact — insulation and window details often have to satisfy Part L and a planning condition at once. Harlow District Council has 14 recorded Article 4 directions, removing permitted development for rear and side extensions and other roof alterations, including rooflights — check the address before assuming PD applies in Mark Hall. We draw the construction details to reconcile both.
A full-plans set for Mark Hall 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 Harlow 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 Mark Hall projects clear planning first, so Harlow District Council's live decision record below sets the context. Harlow District Council granted 79% of its householder applications in the year to 31 March 2026, and Harlow Mill and Old Road North 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 Mark Hall we recommend the full-plans route — particularly on the borough's early postwar houses (81% of 3,380 homes) and 1980s estate 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 Harlow Mill and Old Road North and Mark Hall North and the rest of Mark Hall. Where a project sits in a controlled setting — Mark Hall contains Harlow Mill and Old Road North, Mark Hall North conservation areas (Harlow Mill and Old Road North designated 1998), 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 Mark Hall neighbourhoods and property types where we prepare them most often:
Building regulations drawings for Harlow Mill and Old Road North's conservation area designated in 1998 — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Mark Hall North's conservation area designated in 1987 — 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 Mark Hall.
| Planning permission | Building regulations | |
|---|---|---|
| Question it answers | Should this be built here? | Is it built safely and efficiently? |
| Decided by | Harlow 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 Harlow Mill and Old Road North and Mark Hall North, a planning condition can dictate materials that the building regulations details must then also satisfy.
A fixed process built around how Mark Hall projects are approved and inspected — most construction sets are ready within seven days of survey.
Send us your Mark Hall postcode and scheme. We confirm whether you also need planning, which parts of the regulations apply, and whether Harlow 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 Harlow 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 Mark Hall 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 Mark Hall 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. Harlow District Council is the decision-maker.
For anything structural in Mark Hall — 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 early postwar houses (81% of 3,380 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 Harlow District Council or an approved inspector signs off.
Yes. You can use Harlow 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 Mark Hall address specifically.
Solid-walled period houses — common across Mark Hall, including conservation areas such as Harlow Mill and Old Road North and Mark Hall North — 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. Harlow District Council is the decision-maker.
We price each Mark Hall 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.
