Dormer, hip-to-gable and mansard loft conversion drawings for Fens & Greatham homes — prepared to Hartlepool Borough Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
Hartlepool Borough Council granted 93% of the householder planning decisions it made in its latest published year — 6 points above the 87% England-wide householder average. Fens & Greatham contains the Greatham conservation area (Greatham designated 1974), 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.
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 Hartlepool Borough Council needs a full application. In conservation areas such as Greatham those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Fens & Greatham is determined against an 8-week statutory target.
Greatham (conservation area designated in 1974), Brierton (civil parish within Fens & Greatham), Claxton (civil parish within Fens & Greatham), Newton Bewley (civil parish within Fens & Greatham) and Greatham (civil parish within Fens & Greatham) — these are the Fens & Greatham pockets our drawings cover most. Heritage designations here include Greatham. Hartlepool Borough Council weighs each proposal against Hartlepool Borough Council's adopted local plan and its householder design guidance, where the 2,370 homes here are 26% 1955-1964, 26% 1965-1972, 23% 1973-1982, 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 (26% of 2,370 homes), late-1960s and early-1970s houses (26%) and 1970s and early-1980s houses (23%).
Heritage designation is the single biggest variable in Fens & Greatham, and it is address-specific: Greatham (conservation area designated in 1974). Inside those boundaries permitted development is curtailed and Hartlepool 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, Fens & Greatham takes in Brierton, Claxton, Newton Bewley and Greatham. No Article 4 direction is recorded for Hartlepool Borough Council, but Fens & Greatham's 1 conservation area still limit permitted development on those streets.
On stock, Fens & Greatham is late-1950s and early-1960s houses (26% of 2,370 homes), late-1960s and early-1970s houses (26%) and 1970s and early-1980s houses (23%) — 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. Hartlepool Borough Council decided 117 householder applications in the latest published year and granted 93%, with 52% issued inside the eight-week target. We work from the council's own published record.
The full build-period split for Fens & Greatham runs pre-1900 5% (130 homes), 1900-1918 2% (40 homes), 1930-1939 1% (30 homes), 1945-1954 5% (130 homes), 1955-1964 26% (620 homes), 1965-1972 26% (610 homes), 1973-1982 23% (550 homes), 1983-1992 4% (100 homes), 1993-1999 3% (60 homes) and 2000-2008 2% (40 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.
Hartlepool Borough Council also decides for Burn Valley and Rural West, so a decision in Fens & Greatham 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.

Fens & Greatham's roofs set the brief. The borough is built largely from late-1950s and early-1960s houses (26% of 2,370 homes), late-1960s and early-1970s houses (26%) and 1970s and early-1980s houses (23%), 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. Hartlepool Borough Council assesses loft proposals against Hartlepool Borough Council's adopted local plan and its householder design guidance, 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 Hartlepool Borough Council can verify them. Fens & Greatham contains the Greatham conservation area (Greatham designated 1974), 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.
Fens & Greatham also carries protected streets — Greatham among them. No Article 4 direction is recorded for Hartlepool Borough Council, but Fens & Greatham's 1 conservation area still limit permitted development on those streets. We check your address against those designations before a line is drawn.
Many Fens & Greatham 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 Hartlepool Borough Council if any of these apply:
We draw the roof line, the ridge height and the neighbour's daylight on the page — the relationships Hartlepool Borough 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 Hartlepool Borough Council's real householder decision record, pulled from official planning statistics and updated as new data lands. Hartlepool Borough Council granted 93% of its householder applications in the year to 31 March 2026, and Greatham 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 Greatham, Brierton and Claxton, 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 2,370 homes here are 26% 1955-1964, 26% 1965-1972, 23% 1973-1982, 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 Hartlepool Borough 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.

The right loft in Fens & Greatham 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 Hartlepool Borough 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 Greatham and Article 4 directions can remove permitted-development rights.
A fixed process built around how Hartlepool Borough Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your Fens & Greatham 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 Hartlepool Borough 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 Hartlepool Borough Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Hartlepool Borough 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 Fens & Greatham the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Greatham or on streets with an Article 4 direction. Hartlepool Borough Council is the decision-maker.
Generally no. In conservation areas including Greatham, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Hartlepool Borough Council. No Article 4 direction is recorded for Hartlepool Borough Council, but Fens & Greatham's 1 conservation area still limit permitted development on those streets. We check your exact address before drawing.
On shallow gabled roofs typical of that period's building, common across Fens & Greatham, 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. Hartlepool Borough Council is the decision-maker.
A householder planning application in Fens & Greatham 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. Hartlepool Borough Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Hartlepool Borough 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 Fens & Greatham address specifically.
