Rear dormer drawings for Rother roofs — the box across the back slope that turns a low attic into a full-height room, drawn to Rother District Council's guidance and the volume limits, delivered in days and revised free until your decision, with a free approval-odds check first.
Rother District Council granted 95% of the householder planning decisions it made in its latest published year — 8 points above the 87% England-wide householder average. Rother contains Bexhill Town Centre, Burwash, Northiam conservation areas (Bexhill Town Centre designated 1992), 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 Rother District Council needs a full application. Rother carries at least one Article 4 direction, and conservation areas including Bexhill Town Centre, Burwash and Northiam remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Rother is determined against an 8-week statutory target.
Bexhill Town Centre (conservation area designated in 1992), Burwash (conservation area designated in 1969), Northiam (conservation area designated in 1989), Robertsbridge & Northbridge Street (conservation area designated in 1986), Rye (conservation area designated in 1968), Winchelsea (conservation area designated in 1969), Bexhill Central (ward of Rother), Burwash & the Weald (ward of Rother), Northern Rother (ward of Rother), Robertsbridge (ward of Rother) and Rye & Winchelsea (ward of Rother) — these are the Rother pockets our drawings cover most. Heritage designations here include Bexhill Town Centre, Burwash, Northiam, Robertsbridge & Northbridge Street, Rye and Winchelsea. Rother District Council weighs each proposal against Rother District Council's adopted local plan and its householder design guidance, where the 12,670 homes here are 41% pre-1900, 5% 1945-1954, 4% 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 simple gabled and hipped roofs typical of early postwar building, over Victorian and earlier houses (41% of 12,670 homes), early postwar houses (5%) and late-1960s and early-1970s houses (4%).
Heritage designation is the single biggest variable in Rother, and it is address-specific: Bexhill Town Centre (conservation area designated in 1992), Burwash (conservation area designated in 1969), Northiam (conservation area designated in 1989), Robertsbridge & Northbridge Street (conservation area designated in 1986), Rye (conservation area designated in 1968) and Winchelsea (conservation area designated in 1969). Inside those boundaries permitted development is curtailed and Rother 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, Rother takes in Bexhill Central, Burwash & the Weald, Northern Rother, Robertsbridge and Rye & Winchelsea. Rother District Council has 60 recorded Article 4 directions, removing permitted development for rear and side extensions and roof enlargements such as dormers — check the address before assuming PD applies in the district.
On stock, Rother is Victorian and earlier houses (41% of 12,670 homes), early postwar houses (5%) and late-1960s and early-1970s houses (4%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and simple gabled and hipped roofs typical of early postwar building govern what a loft or rear projection can realistically be. Rother District Council decided 365 householder applications in the latest published year and granted 95%, with 25% issued inside the eight-week target. We work from the council's own published record.
The full build-period split for Rother 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.
Rother District Council also decides for Bexhill Central, Burwash & the Weald, Northern Rother, Robertsbridge and Rye & Winchelsea, so a decision in Rother 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 Article 4 directions recorded for this council include Borough of Bexhill (Normans Bay No.1) Direction, 1971, Borough of Bexhill (Normans Bay No.2) Direction, 1971, Borough of Rye (Camber Castle Estate No. 1) Direction, 1973 and Borough of Rye (Camber Castle Estate No. 2) Direction, 1973. Each removes a specific permitted-development right inside its own boundary, which is why the check is done on the address rather than on the town.

The box dormer is the workhorse loft, and most of Rother is built for it — the borough runs to Victorian and earlier houses (41% of 12,670 homes), early postwar houses (5%) and late-1960s and early-1970s houses (4%) under steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and simple gabled and hipped roofs typical of early postwar building, and a flat-roofed box across the rear slope is the cheapest cubic metre of full-height space those roofs give up. Rother District Council tests the dormer against Rother 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. Rother contains Bexhill Town Centre, Burwash, Northiam conservation areas (Bexhill Town Centre designated 1992), 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 Rother's streets are protected — Bexhill Town Centre, Burwash, Northiam, Robertsbridge & Northbridge Street, Rye and Winchelsea among them — the Class B dormer right is switched off and even a modest rear box needs consent. Rother District Council has 60 recorded Article 4 directions, removing permitted development for rear and side extensions and roof enlargements such as dormers — check the address before assuming PD applies in the district. We confirm the designation before the box is sized.
Many rear dormers in Rother are permitted development, but the volume and position decide it. You will normally need a full application to Rother 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 Rother District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Rother District Council granted 95% of 365 householder decisions in the year to 31 March 2026, 25% of them inside eight weeks. 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 Bexhill Town Centre, Burwash and Northiam, 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 steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, this returns a full-height double and en-suite from what was standing-room-only, usually inside the permitted-development volume.
The 12,670 homes here are 41% pre-1900, 5% 1945-1954, 4% 1965-1972, 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 Rother 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 Rother dormers come up most often:

Whether a dormer in Rother 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 Rother 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 Bexhill Town Centre and Burwash, Class B dormer rights are removed and every dormer needs a full application.
A fixed process built around how Rother District Council validates and decides dormer applications — most drawings are submission-ready within seven days of survey.
Send us your Rother 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 Rother 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 Rother District Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Rother 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 Rother you will need a full application to Rother District Council for a front or side dormer, a box that exceeds the volume, and any dormer in a conservation area such as Bexhill Town Centre and Burwash, 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 Rother 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. Rother 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 Rother 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 Rother 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 Rother 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.
If your dormer is permitted development, a lawful development certificate from Rother 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.
We price each Rother 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 Rother District Council approves, and we confirm at the outset whether your box is permitted development or needs an application.
