Dormer, hip-to-gable and mansard loft conversion drawings for Kimberley homes — prepared to Broxtowe Borough Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
Broxtowe 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. Kimberley contains the Kimberley conservation area (Kimberley designated 1989), 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) housing stock sets the design brief on most streets.
Under Class B, a rear dormer stays permitted development up to 40m³ of added roof volume on a terrace or 50m³ on a semi-detached or detached house, while Class A allows a single-storey rear extension of 3m beyond the original rear wall on a terrace and 4m on a detached house before a full application is needed. In conservation areas such as Kimberley those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Kimberley is determined against an 8-week statutory target.
Kimberley (conservation area designated in 1989), Nuthall (civil parish within Kimberley) and Greasley (civil parish within Kimberley) — these are the Kimberley pockets our drawings cover most. Heritage designations here include Kimberley. Broxtowe Borough Council weighs each proposal against Broxtowe Borough Council's adopted local plan and its householder design guidance, where the 3,170 homes here are 24% pre-1900, 17% 1973-1982, 12% 1983-1992, 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 shallow trussed roofs typical of 1970s building, over Victorian and earlier houses (24% of 3,170 homes), 1970s and early-1980s houses (17%) and 1980s estate houses (12%).
Kimberley's designated heritage is specific, and it is the first thing we check against your address: Kimberley (conservation area designated in 1989). Inside those boundaries permitted development is curtailed and Broxtowe 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, Kimberley takes in Nuthall and Greasley. No Article 4 direction is recorded for Broxtowe Borough Council, but Kimberley's 1 conservation area still limit permitted development on those streets.
On stock, Kimberley is Victorian and earlier houses (24% of 3,170 homes), 1970s and early-1980s houses (17%) and 1980s estate houses (12%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow trussed roofs typical of 1970s building govern what a loft or rear projection can realistically be. Broxtowe Borough Council decided 295 householder applications in the latest published year and granted 96%, with 78% issued inside the eight-week target. Those are the numbers our drawings are prepared against.
The full build-period split for Kimberley runs pre-1900 24% (750 homes), 1900-1918 5% (160 homes), 1919-1929 3% (110 homes), 1930-1939 10% (330 homes), 1945-1954 5% (170 homes), 1955-1964 7% (230 homes), 1965-1972 5% (170 homes), 1973-1982 17% (530 homes), 1983-1992 12% (390 homes), 1993-1999 3% (90 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.
Broxtowe Borough Council also decides for Beeston West, Stapleford South West, Watnall & Nuthall West and Stapleford South East, so a decision in Kimberley 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.

Kimberley's roofs set the brief. The borough is built largely from Victorian and earlier houses (24% of 3,170 homes), 1970s and early-1980s houses (17%) and 1980s estate houses (12%), and its lofts sit under steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow trussed roofs typical of 1970s building — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Broxtowe Borough Council assesses loft proposals against Broxtowe 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 Broxtowe Borough Council can verify them. Kimberley contains the Kimberley conservation area (Kimberley designated 1989), 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.
Kimberley also carries protected streets — Kimberley among them. No Article 4 direction is recorded for Broxtowe Borough Council, but Kimberley's 1 conservation area still limit permitted development on those streets. We check your address against those designations before a line is drawn.
Many Kimberley 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 Broxtowe 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 Broxtowe 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 Broxtowe Borough Council's real householder decision record, pulled from official planning statistics and updated as new data lands. Broxtowe Borough Council granted 96% of its householder applications in the year to 31 March 2026, and Kimberley 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 Kimberley, Nuthall and Greasley, 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 shallow trussed roofs typical of 1970s building, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
The 3,170 homes here are 24% pre-1900, 17% 1973-1982, 12% 1983-1992, 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 Broxtowe 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 Kimberley roofs come up most often:
Loft conversion drawings for Kimberley's conservation area designated in 1989 — measured, volume-checked and drawn to Broxtowe Borough Council's guidance.
Loft conversion drawings for Nuthall's civil parish within Kimberley — measured, volume-checked and drawn to Broxtowe Borough Council's guidance.
Loft conversion drawings for Greasley's civil parish within Kimberley — measured, volume-checked and drawn to Broxtowe Borough Council's guidance.
The right loft in Kimberley 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 Broxtowe 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 Kimberley and Article 4 directions can remove permitted-development rights.
A fixed process built around how Broxtowe Borough Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your Kimberley 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 Broxtowe 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 Broxtowe Borough Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Broxtowe 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 Kimberley the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Kimberley or on streets with an Article 4 direction. Broxtowe Borough Council is the decision-maker.
Generally no. In conservation areas including Kimberley, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Broxtowe Borough Council. No Article 4 direction is recorded for Broxtowe Borough Council, but Kimberley's 1 conservation area 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 Kimberley, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is shallow trussed roofs typical of 1970s 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. Broxtowe Borough Council is the decision-maker.
A householder planning application in Kimberley 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. Broxtowe Borough Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Broxtowe 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 Kimberley address specifically.
Every roof is different, so we quote each Kimberley project individually — a fixed, no-obligation price back within one working day.
