Dormer, hip-to-gable and mansard loft conversion drawings for Bush Fair homes — prepared to Harlow District Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score 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. Bush Fair contains Netteswellbury, Puffers Green, Tye Green conservation areas (Netteswellbury designated 1986), 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. Bush Fair carries at least one Article 4 direction, and conservation areas including Netteswellbury, Puffers Green and Tye Green remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Bush Fair is determined against an 8-week statutory target.
Netteswellbury (conservation area designated in 1986), Puffers Green (conservation area designated in 1995) and Tye Green (conservation area designated in 1999) — these are the Bush Fair pockets our drawings cover most. Heritage designations here include Netteswellbury, Puffers Green and Tye Green. Harlow District Council weighs each proposal against the adopted Harlow local plan and Harlow District Council's design guidance for householder work, where the 4,010 homes here are 72% 1955-1964, 12% 1965-1972, 7% 1945-1954, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow gabled roofs typical of that period's building and shallow-pitched roofs and integral garages typical of that period's building, over late-1950s and early-1960s houses (72% of 4,010 homes), late-1960s and early-1970s houses (12%) and early postwar houses (7%).
Before anything is drawn we check your address against the designations that apply in Bush Fair: Netteswellbury (conservation area designated in 1986), Puffers Green (conservation area designated in 1995) and Tye Green (conservation area designated in 1999). 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 Bush Fair.
On stock, Bush Fair is late-1950s and early-1960s houses (72% of 4,010 homes), late-1960s and early-1970s houses (12%) and early postwar houses (7%) — which is why shallow gabled roofs typical of that period's building and shallow-pitched roofs and integral garages typical of that period's 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 Bush Fair runs pre-1900 0% (10 homes), 1945-1954 7% (300 homes), 1955-1964 72% (2,900 homes), 1965-1972 12% (500 homes), 1973-1982 2% (100 homes), 1983-1992 1% (50 homes), 1993-1999 1% (50 homes) and 2000-2008 1% (30 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 Mark Hall and Old Harlow, so a decision in Bush Fair 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.

Bush Fair's roofs set the brief. The borough is built largely from late-1950s and early-1960s houses (72% of 4,010 homes), late-1960s and early-1970s houses (12%) and early postwar houses (7%), and its lofts sit under shallow gabled roofs typical of that period's building and shallow-pitched roofs and integral garages typical of that period's building — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Harlow District Council assesses loft proposals against the adopted Harlow local plan and Harlow District Council's design guidance for householder work, and its case officers read each roof against the pair next door and the wider street before they read the plans.
That makes drawing quality decisive. We measure ridge and eaves heights, roof pitch and the existing stair, calculate the added volume against the permitted-development limits exactly, and show the workings on the drawings so Harlow District Council can verify them. Bush Fair contains Netteswellbury, Puffers Green, Tye Green conservation areas (Netteswellbury designated 1986), so materials, fenestration and roof form are assessed against the appraisal, so we resolve it on the page rather than leave it for the case officer to raise.
Bush Fair also carries protected streets — Netteswellbury, Puffers Green and Tye Green among them. 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 Bush Fair. We check your address against those designations before a line is drawn.
Many Bush Fair loft conversions proceed without planning permission — a rear dormer within the permitted-development volume limits (40 cubic metres on a terrace, 50 on a semi or detached house) is usually lawful. You will normally need a full application to Harlow District Council if any of these apply:
We draw the roof line, the ridge height and the neighbour's daylight on the page — the relationships Harlow District Council's officers check first — and submit a validation-complete pack, whether that is a lawful development certificate or a full householder application.
Below is Harlow District Council's real householder decision record, pulled from official planning statistics and updated as new data lands. Harlow District Council granted 79% of its householder applications in the year to 31 March 2026, and Netteswellbury shapes what is approved here. Professionally prepared loft drawings anticipate those pressure points before submission, which is why complete, policy-literate packs are decided faster and refused less often than DIY applications.

Across Netteswellbury, Puffers Green and Tye Green, the recurring loft is the rear dormer — a box across the back roof slope that turns a cramped attic into a full-height double bedroom and en-suite. On shallow gabled roofs typical of that period's building, that is usually the most efficient use of the roof; where the stock is shallow-pitched roofs and integral garages typical of that period's building, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
The 4,010 homes here are 72% 1955-1964, 12% 1965-1972, 7% 1945-1954, which is what sets the realistic roof and rear-projection options. We draw the dormer inside the volume allowance, keep the flat-roof build-up below the ridge, and set the face back from the eaves as the rules require — so the pack answers Harlow District Council's questions before they are asked. Where permitted-development rights are exhausted or removed, we prepare a householder application composed to the borough's roof-alteration guidance instead.
We draw loft conversions on every street in the borough. A few of the neighbourhoods where Bush Fair roofs come up most often:
Loft conversion drawings for Netteswellbury's conservation area designated in 1986 — measured, volume-checked and drawn to Harlow District Council's guidance.
Loft conversion drawings for Puffers Green's conservation area designated in 1995 — measured, volume-checked and drawn to Harlow District Council's guidance.
Loft conversion drawings for Tye Green's conservation area designated in 1999 — measured, volume-checked and drawn to Harlow District Council's guidance.
The right loft in Bush Fair depends on your roof. This is how the main types compare on planning route and the space they add.
| Loft type | Permitted development? | Space & headroom | What Harlow District Council checks |
|---|---|---|---|
| Rear dormer | Usually yes, within volume limits | Full-height double room at the back | Volume, set-back from eaves, ridge height |
| Hip-to-gable | No — full application | Extends the whole side of the roof | Roof bulk and the symmetry of the pair |
| Mansard | No — full application | Maximum floor area across the roof | Street character, especially in conservation areas |
| Rooflights only | Usually yes (Class C) | Light and headroom, no extra footprint | Whether rooflights sit within the existing slope |
Route depends on your street — conservation areas such as Netteswellbury and Puffers Green and Article 4 directions can remove permitted-development rights.
A fixed process built around how Harlow District Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your Bush Fair postcode and roof type. We confirm your conservation and Article 4 status, how much permitted-development volume you have left, and score your odds against live Harlow District Council decisions.
We measure ridge and eaves heights, roof pitch, joist levels and the existing stair — the numbers the volume calculation and head heights depend on.
Chartered designers develop the dormer, hip-to-gable or mansard to your brief, drawn inside the Class B limits or to Harlow District Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Harlow District Council issues its decision.
Often not. A rear dormer within 40 cubic metres on a terrace, or 50 on a semi-detached or detached house, set back from the eaves and no higher than the ridge, is usually permitted development. In Bush Fair the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Netteswellbury and Puffers Green or on streets with an Article 4 direction. Harlow District Council is the decision-maker.
Generally no. In conservation areas including Netteswellbury and Puffers Green, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Harlow District Council. 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 Bush Fair. We check your exact address before drawing.
On shallow gabled roofs typical of that period's building, common across Bush Fair, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is shallow-pitched roofs and integral garages typical of that period's building, a hip-to-gable followed by a rear dormer gains far more usable space but needs planning permission. Our survey confirms which your roof supports before we draw. Harlow District Council is the decision-maker.
A householder planning application in Bush Fair runs to a statutory eight-week target, and a lawful development certificate to eight weeks as well, though validation can add time if the pack is incomplete. We submit validation-complete drawings and manage case-officer queries to keep the decision on track. Harlow District Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Harlow District Council is council-stamped proof of that — worth having, because every buyer's solicitor will ask for it when you sell. We prepare and submit the certificate application with the same drawing pack. This applies to your Bush Fair address specifically.
Every roof is different, so we quote each Bush Fair project individually — a fixed, no-obligation price back within one working day. The quote covers the full drawing pack with free revisions until Harlow District Council approves, and we tell you upfront whether your loft qualifies as permitted development.
