Dormer, hip-to-gable and mansard loft conversion drawings for West Lindsey homes — prepared to West Lindsey District Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
West Lindsey District Council granted 94% of the householder planning decisions it made in its latest published year — 7 points above the 87% England-wide householder average. West Lindsey contains Brattleby, Burton, Caistor conservation areas (Brattleby designated 1981), 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.
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 West Lindsey District Council needs a full application. In conservation areas such as Brattleby, Burton and Caistor those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in West Lindsey is determined against an 8-week statutory target.
Brattleby (conservation area designated in 1981), Burton (conservation area designated in 1989), Caistor (designated conservation area), East Stockwith (designated conservation area), Fillingham (conservation area designated in 1993), Glentham (conservation area designated in 1994), Glentworth (conservation area designated in 1993), Great Limber (conservation area designated in 1990), Caistor and Yarborough (ward of West Lindsey), Cherry Willingham (ward of West Lindsey), Dunholme and Welton (ward of West Lindsey), Hemswell (ward of West Lindsey), Market Rasen (ward of West Lindsey), Nettleham (ward of West Lindsey), Saxilby (ward of West Lindsey) and Scampton (ward of West Lindsey) — these are the West Lindsey pockets our drawings cover most. Heritage designations here include Brattleby, Burton, Caistor, East Stockwith, Fillingham, Glentham, Glentworth and Great Limber. West Lindsey District Council weighs each proposal against the adopted West Lindsey local plan and West Lindsey District Council's design guidance for householder work, where the 29,020 homes here are 13% pre-1900, 11% 2000-2008, 11% 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 trussed-rafter roofs typical of 2000s building, over Victorian and earlier houses (13% of 29,020 homes), 2000s houses and apartments (11%) and late-1960s and early-1970s houses (11%).
Heritage designation is the single biggest variable in West Lindsey, and it is address-specific: Brattleby (conservation area designated in 1981), Burton (conservation area designated in 1989), Caistor (designated conservation area), East Stockwith (designated conservation area), Fillingham (conservation area designated in 1993), Glentham (conservation area designated in 1994), Glentworth (conservation area designated in 1993) and Great Limber (conservation area designated in 1990). Inside those boundaries permitted development is curtailed and West Lindsey 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, West Lindsey takes in Caistor and Yarborough, Cherry Willingham, Dunholme and Welton, Hemswell, Market Rasen, Nettleham, Saxilby and Scampton. No Article 4 direction is recorded for West Lindsey District Council, but the district's 8 conservation areas still limit permitted development on those streets.
On stock, West Lindsey is Victorian and earlier houses (13% of 29,020 homes), 2000s houses and apartments (11%) and late-1960s and early-1970s houses (11%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and trussed-rafter roofs typical of 2000s building govern what a loft or rear projection can realistically be. West Lindsey District Council decided 260 householder applications in the latest published year and granted 94%, with 72% issued inside the eight-week target. We work from the council's own published record.
The full build-period split for West Lindsey 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.
West Lindsey District Council also decides for Caistor and Yarborough, Cherry Willingham, Dunholme and Welton, Hemswell, Market Rasen, Nettleham, Saxilby and Scampton, so a decision in West Lindsey 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.

West Lindsey's roofs set the brief. The borough is built largely from Victorian and earlier houses (13% of 29,020 homes), 2000s houses and apartments (11%) and late-1960s and early-1970s houses (11%), and its lofts sit under steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and trussed-rafter roofs typical of 2000s building — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. West Lindsey District Council assesses loft proposals against the adopted West Lindsey local plan and West Lindsey 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 West Lindsey District Council can verify them. West Lindsey contains Brattleby, Burton, Caistor conservation areas (Brattleby designated 1981), 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.
West Lindsey also carries protected streets — Brattleby, Burton, Caistor, East Stockwith, Fillingham, Glentham, Glentworth and Great Limber among them. No Article 4 direction is recorded for West Lindsey District Council, but the district's 8 conservation areas still limit permitted development on those streets. We check your address against those designations before a line is drawn.
Many West Lindsey 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 West Lindsey 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 West Lindsey 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 West Lindsey District Council's real householder decision record, pulled from official planning statistics and updated as new data lands. West Lindsey District Council granted 94% of 260 householder decisions in the year to 31 March 2026, 72% of them inside eight weeks. 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 Brattleby, Burton and Caistor, 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 steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, that is usually the most efficient use of the roof; where the stock is trussed-rafter roofs typical of 2000s building, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
The 29,020 homes here are 13% pre-1900, 11% 2000-2008, 11% 1965-1972, 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 West Lindsey 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 West Lindsey roofs come up most often:

The right loft in West Lindsey 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 West Lindsey 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 Brattleby and Burton and Article 4 directions can remove permitted-development rights.
A fixed process built around how West Lindsey District Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your West Lindsey 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 West Lindsey 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 West Lindsey District Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until West Lindsey 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 West Lindsey the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Brattleby and Burton or on streets with an Article 4 direction. West Lindsey District Council is the decision-maker.
Generally no. In conservation areas including Brattleby and Burton, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to West Lindsey District Council. No Article 4 direction is recorded for West Lindsey District Council, but the district's 8 conservation areas still limit permitted development on those streets. We check your exact address before drawing.
On steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, common across West Lindsey, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is trussed-rafter roofs typical of 2000s 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. West Lindsey District Council is the decision-maker.
A householder planning application in West Lindsey 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. West Lindsey District Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from West Lindsey 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.
Every roof is different, so we quote each West Lindsey project individually — a fixed, no-obligation price back within one working day.
