Rear dormer drawings for Ollerton roofs — the box across the back slope that turns a low attic into a full-height room, drawn to Newark and Sherwood District Council's guidance and the volume limits, delivered in days and revised free until your decision, with a free approval-odds check first.
Newark and Sherwood 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. Ollerton contains the Ollerton conservation area, so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
Before permission is required, Class B allows 40m³ of added loft volume on a terrace and 50m³ on a semi or detached house, and Class A allows a 3m single-storey rear extension on a terrace or 4m on a detached house. In conservation areas such as Ollerton those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Ollerton is determined against an 8-week statutory target.
Ollerton (designated conservation area), Perlethorpe cum Budby (civil parish within Ollerton) and Ollerton and Boughton (civil parish within Ollerton) — these are the Ollerton pockets our drawings cover most. Heritage designations here include Ollerton. Newark and Sherwood District Council weighs each proposal against the adopted Newark and Sherwood local plan and Newark and Sherwood District Council's design guidance for householder work, where the 4,660 homes here are 17% 1955-1964, 15% 1919-1929, 14% 1965-1972, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow gabled roofs typical of that period's building and hipped tiled roofs typical of early interwar building, over late-1950s and early-1960s houses (17% of 4,660 homes), early interwar houses (15%) and late-1960s and early-1970s houses (14%).
What is permitted in Ollerton turns on designation first, so that is where we start: Ollerton (designated conservation area). Inside those boundaries permitted development is curtailed and Newark and Sherwood 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, Ollerton takes in Perlethorpe cum Budby and Ollerton and Boughton. No Article 4 direction is recorded for Newark and Sherwood District Council, but Ollerton's 1 conservation area still limit permitted development on those streets.
On stock, Ollerton is late-1950s and early-1960s houses (17% of 4,660 homes), early interwar houses (15%) and late-1960s and early-1970s houses (14%) — which is why shallow gabled roofs typical of that period's building and hipped tiled roofs typical of early interwar building govern what a loft or rear projection can realistically be. Newark and Sherwood District Council decided 341 householder applications in the latest published year and granted 96%, with 50% issued inside the eight-week target. We draw to that record rather than to a national average.
The full build-period split for Ollerton runs pre-1900 4% (170 homes), 1900-1918 0% (20 homes), 1919-1929 15% (690 homes), 1930-1939 1% (50 homes), 1945-1954 9% (440 homes), 1955-1964 17% (790 homes), 1965-1972 14% (650 homes), 1973-1982 10% (450 homes), 1983-1992 3% (150 homes), 1993-1999 3% (160 homes) and 2000-2008 3% (150 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.
Newark and Sherwood District Council also decides for Balderton South, Bilsthorpe, Boughton, Collingham, Edwinstowe & Clipstone, Lowdham, Southwell and Sutton-on-Trent, so a decision in Ollerton 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 Ollerton is built for it — the borough runs to late-1950s and early-1960s houses (17% of 4,660 homes), early interwar houses (15%) and late-1960s and early-1970s houses (14%) under shallow gabled roofs typical of that period's building and hipped tiled roofs typical of early interwar building, and a flat-roofed box across the rear slope is the cheapest cubic metre of full-height space those roofs give up. Newark and Sherwood District Council tests the dormer against the adopted Newark and Sherwood local plan and Newark and Sherwood District Council's design guidance for householder work, 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. Ollerton contains the Ollerton conservation area, 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 Ollerton's streets are protected — Ollerton 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 Newark and Sherwood District Council, but Ollerton's 1 conservation area still limit permitted development on those streets. We confirm the designation before the box is sized.
Many rear dormers in Ollerton are permitted development, but the volume and position decide it. You will normally need a full application to Newark and Sherwood 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 Newark and Sherwood District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Newark and Sherwood District Council granted 96% of its householder applications in the year to 31 March 2026, and Ollerton 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 Ollerton, Perlethorpe cum Budby and Ollerton and Boughton, 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 shallow gabled roofs typical of that period's building, this returns a full-height double and en-suite from what was standing-room-only, usually inside the permitted-development volume.
The 4,660 homes here are 17% 1955-1964, 15% 1919-1929, 14% 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 Newark and Sherwood 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 Ollerton dormers come up most often:

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