Dormer, hip-to-gable and mansard loft conversion drawings for Five Village homes — prepared to Boston Borough Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
Boston Borough Council granted 96% of the householder planning decisions it made in its latest published year — 9 points above the 87% England-wide householder average. Five Village contains Bicker, Wigtoft conservation areas (Bicker designated 1970), 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. In conservation areas such as Bicker and Wigtoft those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Five Village is determined against an 8-week statutory target.
Bicker (conservation area designated in 1970), Wigtoft (conservation area designated in 1971), Algarkirk (civil parish within Five Village), Bicker (civil parish within Five Village), Fosdyke (civil parish within Five Village), Sutterton (civil parish within Five Village) and Wigtoft (civil parish within Five Village) — these are the Five Village pockets our drawings cover most. Heritage designations here include Bicker and Wigtoft. Boston Borough Council weighs each proposal against the adopted Boston local plan and Boston Borough Council's design guidance for householder work, where the 1,870 homes here are 17% 2000-2008, 14% pre-1900, 11% 1945-1954, which is what sets the realistic roof and rear-projection options. On roofs the borough is trussed-rafter roofs typical of 2000s building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, over 2000s houses and apartments (17% of 1,870 homes), Victorian and earlier houses (14%) and early postwar houses (11%).
Before anything is drawn we check your address against the designations that apply in Five Village: Bicker (conservation area designated in 1970) and Wigtoft (conservation area designated in 1971). Inside those boundaries permitted development is curtailed and Boston 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, Five Village takes in Algarkirk, Bicker, Fosdyke, Sutterton and Wigtoft. No Article 4 direction is recorded for Boston Borough Council, but Five Village's 2 conservation areas still limit permitted development on those streets.
On stock, Five Village is 2000s houses and apartments (17% of 1,870 homes), Victorian and earlier houses (14%) and early postwar houses (11%) — which is why trussed-rafter roofs typical of 2000s building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building govern what a loft or rear projection can realistically be. Boston Borough Council decided 81 householder applications in the latest published year and granted 96%, with 70% issued inside the eight-week target. That decision record, not a national figure, is what we design to.
The full build-period split for Five Village runs pre-1900 14% (270 homes), 1900-1918 3% (60 homes), 1919-1929 5% (100 homes), 1930-1939 9% (170 homes), 1945-1954 11% (200 homes), 1955-1964 6% (110 homes), 1965-1972 4% (80 homes), 1973-1982 7% (130 homes), 1983-1992 6% (120 homes), 1993-1999 4% (70 homes) and 2000-2008 17% (310 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.
Boston Borough Council also decides for Kirton and Frampton and Old Leake and Wrangle, so a decision in Five Village 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.

Five Village's roofs set the brief. The borough is built largely from 2000s houses and apartments (17% of 1,870 homes), Victorian and earlier houses (14%) and early postwar houses (11%), and its lofts sit under trussed-rafter roofs typical of 2000s building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Boston Borough Council assesses loft proposals against the adopted Boston local plan and Boston Borough 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 Boston Borough Council can verify them. Five Village contains Bicker, Wigtoft conservation areas (Bicker designated 1970), 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.
Five Village also carries protected streets — Bicker and Wigtoft among them. No Article 4 direction is recorded for Boston Borough Council, but Five Village's 2 conservation areas still limit permitted development on those streets. We check your address against those designations before a line is drawn.
Many Five Village 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 Boston 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 Boston 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 Boston Borough Council's real householder decision record, pulled from official planning statistics and updated as new data lands. Boston Borough Council granted 96% of its householder applications in the year to 31 March 2026, and Bicker 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 Bicker, Wigtoft and Algarkirk, 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 trussed-rafter roofs typical of 2000s building, that is usually the most efficient use of the roof; where the stock is steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
The 1,870 homes here are 17% 2000-2008, 14% pre-1900, 11% 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 Boston 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.
We draw loft conversions on every street in the borough. A few of the neighbourhoods where Five Village roofs come up most often:

The right loft in Five Village 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 Boston 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 Bicker and Wigtoft and Article 4 directions can remove permitted-development rights.
A fixed process built around how Boston Borough Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your Five Village 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 Boston 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 Boston Borough Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Boston 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 Five Village the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Bicker and Wigtoft or on streets with an Article 4 direction. Boston Borough Council is the decision-maker.
Generally no. In conservation areas including Bicker and Wigtoft, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Boston Borough Council. No Article 4 direction is recorded for Boston Borough Council, but Five Village's 2 conservation areas still limit permitted development on those streets. We check your exact address before drawing.
On trussed-rafter roofs typical of 2000s building, common across Five Village, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 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. Boston Borough Council is the decision-maker.
A householder planning application in Five Village 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. Boston Borough Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Boston 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 Five Village address specifically.
Every roof is different, so we quote each Five Village project individually — a fixed, no-obligation price back within one working day. The quote covers the full drawing pack with free revisions until Boston Borough Council approves, and we tell you upfront whether your loft qualifies as permitted development.
