Rear dormer drawings for Lickey Hills roofs — the box across the back slope that turns a low attic into a full-height room, drawn to Bromsgrove District Council's guidance and the volume limits, delivered in days and revised free until your decision, with a free approval-odds check first.
Bromsgrove District Council granted 96% of the householder planning decisions it made in its latest published year — 9 points above the 87% England-wide householder average. Lickey Hills contains the Barnt Green conservation area (Barnt Green designated 2000), 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.
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 Bromsgrove District Council needs a full application. In conservation areas such as Barnt Green those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Lickey Hills is determined against an 8-week statutory target.
Barnt Green (conservation area designated in 2000) and Lickey and Blackwell (civil parish within Lickey Hills) — these are the Lickey Hills pockets our drawings cover most. Heritage designations here include Barnt Green. Bromsgrove District Council weighs each proposal against Bromsgrove District Council's adopted local plan and its householder design guidance, where the 1,610 homes here are 18% 1983-1992, 13% 1993-1999, 11% pre-1900, which is what sets the realistic roof and rear-projection options. On roofs the borough is trussed-rafter roofs typical of 1980s building and trussed-rafter roofs typical of 1990s building, over 1980s estate houses (18% of 1,610 homes), 1990s estate houses (13%) and Victorian and earlier houses (11%).
Heritage designation is the single biggest variable in Lickey Hills, and it is address-specific: Barnt Green (conservation area designated in 2000). Inside those boundaries permitted development is curtailed and Bromsgrove 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, Lickey Hills takes in Lickey and Blackwell. No Article 4 direction is recorded for Bromsgrove District Council, but Lickey Hills's 1 conservation area still limit permitted development on those streets.
On stock, Lickey Hills is 1980s estate houses (18% of 1,610 homes), 1990s estate houses (13%) and Victorian and earlier houses (11%) — which is why trussed-rafter roofs typical of 1980s building and trussed-rafter roofs typical of 1990s building govern what a loft or rear projection can realistically be. Bromsgrove District Council decided 288 householder applications in the latest published year and granted 96%, with 62% issued inside the eight-week target. We work from the council's own published record.
The full build-period split for Lickey Hills runs pre-1900 11% (170 homes), 1900-1918 9% (140 homes), 1919-1929 11% (170 homes), 1930-1939 8% (130 homes), 1945-1954 1% (10 homes), 1955-1964 6% (90 homes), 1965-1972 7% (110 homes), 1973-1982 7% (110 homes), 1983-1992 18% (290 homes), 1993-1999 13% (210 homes) and 2000-2008 4% (70 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.
Bromsgrove District Council also decides for Belbroughton & Romsley, Sanders Park and Tardebigge, so a decision in Lickey Hills 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 box dormer is the workhorse loft, and most of Lickey Hills is built for it — the borough runs to 1980s estate houses (18% of 1,610 homes), 1990s estate houses (13%) and Victorian and earlier houses (11%) under trussed-rafter roofs typical of 1980s building and trussed-rafter roofs typical of 1990s building, and a flat-roofed box across the rear slope is the cheapest cubic metre of full-height space those roofs give up. Bromsgrove District Council tests the dormer against Bromsgrove District Council's adopted local plan and its householder design guidance, and because permitted development turns on a number, the volume you propose against the volume you have left is the first thing an officer or a certificate checks.
That is why the arithmetic goes on the drawings. We calculate the box against the 40- or 50-cubic-metre allowance, count any earlier roof enlargement into the total, hold the flat roof below the ridge and set the face back off the eaves so the dormer reads as subordinate. Lickey Hills contains the Barnt Green conservation area (Barnt Green designated 2000), so materials, fenestration and roof form are assessed against the appraisal, so the cheeks, the window line and the material are drawn to answer it rather than invite a query.
Where Lickey Hills's streets are protected — Barnt Green among them — the Class B dormer right is switched off and even a modest rear box needs consent. No Article 4 direction is recorded for Bromsgrove District Council, but Lickey Hills's 1 conservation area still limit permitted development on those streets. We confirm the designation before the box is sized.
Many rear dormers in Lickey Hills are permitted development, but the volume and position decide it. You will normally need a full application to Bromsgrove District Council if any of these apply:
We draw the box within its volume allowance, the flat roof below the ridge and the face set back off the eaves — the three things a dormer stands or falls on — and submit a validation-complete pack, whether that is a lawful development certificate or a full householder application.
Below is Bromsgrove District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Bromsgrove District Council granted 96% of its householder applications in the year to 31 March 2026, and Barnt Green shapes what is approved here. A dormer is decided on volume and set-back, so a pack that shows the calculation and the eaves detail is cleared faster and refused less often than a DIY submission.

Across Barnt Green and Lickey and Blackwell, the dormer that goes through is the subordinate rear box: flat roof kept low, cheeks clad to recede, side windows obscure-glazed against overlooking, and the whole thing set back so the original eaves line still reads from the garden. On trussed-rafter roofs typical of 1980s building, this returns a full-height double and en-suite from what was standing-room-only, usually inside the permitted-development volume.
The 1,610 homes here are 18% 1983-1992, 13% 1993-1999, 11% pre-1900, which is what sets the realistic roof and rear-projection options. We keep the box off the ridge, match the cheek material to the roof, and where the volume is already spent — or the street is designated — draw the dormer as a householder application composed to Bromsgrove District Council's roof-alteration guidance rather than push a certificate that would be refused.
We draw rear dormers on the terraced and semi-detached streets across the borough. A few of the neighbourhoods where Lickey Hills dormers come up most often:
Dormer loft drawings for Barnt Green's conservation area designated in 2000 — volume-checked, set-back-detailed and drawn to Bromsgrove District Council's guidance.
Dormer loft drawings for Lickey and Blackwell's civil parish within Lickey Hills — volume-checked, set-back-detailed and drawn to Bromsgrove District Council's guidance.
Whether a dormer in Lickey Hills needs permission comes down to where it sits and how big the box is. This is how the cases compare.
| Dormer type | Permitted development? | What it gains | What Bromsgrove District Council checks |
|---|---|---|---|
| Rear box, within volume | Usually yes | Full-height room across the back | Volume total, 20cm eaves set-back |
| Rear box, over volume limit | No — full application | A larger room | How far over the allowance, bulk |
| Front or side dormer | No — full application | Light to the front rooms | Visibility from the street, character |
| Dormer in a conservation area | No — full application | Same space, extra scrutiny | Roof form and street appearance |
In conservation areas such as Barnt Green, Class B dormer rights are removed and every dormer needs a full application.
A fixed process built around how Bromsgrove District Council validates and decides dormer applications — most drawings are submission-ready within seven days of survey.
Send us your Lickey Hills postcode and roof type. We confirm your conservation and Article 4 status, work out how much permitted-development volume you have left, and score your odds against live Bromsgrove District Council decisions.
We measure ridge and eaves heights, roof pitch and the existing loft floor — the numbers the volume calculation, the set-back and the head heights depend on.
Chartered designers develop the box to your brief, drawn inside the Class B volume limits or, where those are exhausted or removed, to Bromsgrove District Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Bromsgrove District Council issues its decision.
Often not. A rear box dormer within 40 cubic metres on a terrace, or 50 on a semi or detached house, set back at least 20 centimetres from the eaves and kept below the ridge, is usually permitted development. In Lickey Hills you will need a full application to Bromsgrove District Council for a front or side dormer, a box that exceeds the volume, and any dormer in a conservation area such as Barnt Green, where those rights are removed.
The permitted-development limit is a volume, not a footprint: 40 cubic metres of added roof space on a terraced house and 50 on a semi-detached or detached one, and any earlier loft enlargement counts against that total. In Lickey Hills the box must also sit below the ridge and back from the eaves. We measure your roof and calculate the exact volume you have left before drawing. Bromsgrove District Council is the decision-maker.
Not under permitted development. A dormer on the front roof slope, or one facing a highway, always needs a full application to Bromsgrove District Council, because it changes how the house reads from the street. Rear box dormers are far more likely to be approved — or to be permitted development outright — which is why almost every Lickey Hills dormer we draw sits on the back slope.
Often, on a terrace or semi. If the dormer or the loft steelwork meets the party wall with your neighbour, the Party Wall etc. Act applies and notice must be served before work starts — separately from Bromsgrove District Council's planning decision. We flag the party-wall junction on the drawings so a surveyor can be appointed early and the build is not held up. This applies to your Lickey Hills address specifically.
If your dormer is permitted development, a lawful development certificate from Bromsgrove District Council is council-stamped proof of it — worth holding, because a buyer's solicitor will ask for it when you sell. We prepare and submit the certificate with the same measured drawing pack that shows the box within its volume allowance. This applies to your Lickey Hills address specifically.
We price each Lickey Hills dormer individually, because the roof pitch and the volume left vary house to house, and send a fixed, no-obligation quote within one working day. It covers the full drawing pack with free revisions until Bromsgrove District Council approves, and we confirm at the outset whether your box is permitted development or needs an application.
