Back-of-house extension drawings for Newtown, Reading homes — the glazed kitchen-diner across the rear, drawn to Reading Borough Council's depth and daylight limits, delivered in days and revised free until your decision, with a free approval-odds check first.
Reading Borough Council granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. The HMO Article 4 direction means further HMO conversions are normally refused where they would exceed the 25-per-cent threshold within 50 metres, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837) and Victorian (1837–1901) 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. Newtown, Reading carries at least one Article 4 direction, and conservation areas including Eldon Square, Alexandra Road and South Park remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Newtown, Reading is determined against an 8-week statutory target.
New Town grid (the tight grid of Victorian terraces off Cholmeley and Kensington roads), Eldon Square (Georgian and early-Victorian houses around the square's gardens), Cemetery Junction (Victorian shopping parades and terraces at the eastern gateway), Palmer Park (terraces facing the Victorian park given to the town by the Palmer family), Alexandra Road (Victorian streets in the Alexandra Road conservation area) and East Reading (long red-brick terraces stretching toward the university) — these are the Newtown, Reading pockets our drawings cover most. Heritage designations here include Eldon Square, Alexandra Road and South Park. Reading Borough Council weighs each proposal against the Reading Borough Local Plan (2019), where the Eldon Square conservation area protects one of the town's finest Georgian set-pieces, limiting roof and frontage changes nearby. Parts of Newtown are already converted flats and HMOs, which hold no householder permitted-development rights of their own.. On roofs the borough is pitched and gabled roofs on the terraces and parapet and valley roofs on the Eldon Square houses, over Victorian workers' terraces on the tight New Town grid, red-brick artisan cottages built for the town's Victorian industries and Georgian and early-Victorian houses around Eldon Square.
The rear extension is the workhorse of Newtown, Reading home improvement — it is how a dark back kitchen becomes an open family room facing the garden. Because the borough is built largely from Victorian workers' terraces on the tight New Town grid, red-brick artisan cottages built for the town's Victorian industries and Georgian and early-Victorian houses around Eldon Square, most back walls sit close to a neighbour on at least one side, and that proximity, not the design, is what Reading Borough Council scrutinises. The council reads the proposal against the Reading Borough Local Plan (2019), and the first line an officer draws is the 45-degree splay from the neighbour's nearest window.
So the drawings live or die on geometry. We set the depth against the exact permitted-development figure, hold the eaves and the flat-roof or lantern build-up under the 4-metre height ceiling, and show the projection tested against both the 45-degree plan angle and the 25-degree section angle to the neighbouring windows. The HMO Article 4 direction means further HMO conversions are normally refused where they would exceed the 25-per-cent threshold within 50 metres, so the rear elevation is composed around it rather than corrected after an objection.
Where the property sits in a conservation area — Eldon Square, Alexandra Road and South Park among Newtown, Reading's — the larger-home extension route is switched off and even a modest rear addition needs consent. Newtown falls within Park ward, one of the three areas covered by Reading's HMO Article 4 direction, so the automatic right to convert a house to a small HMO has been withdrawn across this grid of workers' terraces east of the centre. We confirm the designation before the survey.
Many single-storey rear extensions in Newtown, Reading are permitted development and need no application. You will normally need to apply to Reading Borough Council, or use the larger-home prior-approval route, if any of these apply:
We draw the depth, the roof build-up and the daylight splays to each neighbour on the page — the tests Reading Borough Council's officers apply first — and submit a validation-complete pack, whether that is a lawful development certificate, a larger-home prior-approval notice or a full householder application.
Below is Reading Borough Council's real householder decision record, taken from official planning statistics and refreshed as new data lands. Newtown grants most householder applications, yet as a densely terraced Article 4 area with the Eldon Square set-piece at its heart, conservation and HMO controls shape the exceptions. Rear extensions turn most often on neighbour daylight and depth, so a drawing pack that proves those tests upfront is decided faster and refused less often than a DIY submission.

Across New Town grid, Eldon Square and Cemetery Junction, the approved rear extension is typically a single-storey glazed box within the depth limit, roofed either flat with a lantern or in a shallow mono-pitch, and finished in brick or render to match the host wall. On the borough's victorian workers' terraces on the tight new town grid, keeping the projection to the permitted-development figure often avoids an application entirely; where owners want the full 6 metres, the larger-home route succeeds when the neighbour-consultation period passes without a sustained objection.
The Eldon Square conservation area protects one of the town's finest Georgian set-pieces, limiting roof and frontage changes nearby. We keep the extension inside the daylight splays, set any glazed roof below the first-floor cill, and retain the garden depth Reading Borough Council expects — so the back elevation answers the amenity case before a neighbour can lodge one. Two-storey rear extensions we draw with the 7-metre boundary gap and privacy screening resolved on the plan.
We draw rear extensions on every street in the borough. A few of the neighbourhoods where Newtown, Reading back-of-house projects come up most often:

How far you can extend at the back in Newtown, Reading depends on your house type and the route you take. This is how the options compare.
| Route | Depth allowed | Consent needed | What Reading Borough Council checks |
|---|---|---|---|
| Standard permitted development | 3m terrace/semi · 4m detached | Lawful development certificate (optional) | Depth, 4m height, materials |
| Larger-home prior approval | 6m terrace/semi · 8m detached | Prior-approval notice + neighbour consultation | Neighbour objections on amenity |
| Full householder application | Beyond the above, or two-storey | Full planning permission | Daylight (45°/25°), bulk, garden retained |
| Conservation area | Case by case | Full planning permission | Character, roof form, boundary treatment |
The larger-home route is switched off on designated land — conservation areas such as Eldon Square and Alexandra Road and Article 4 streets need a full application.
A fixed process built around how Reading Borough Council validates and decides rear-extension applications — most drawings are submission-ready within seven days of survey.
Send us your Newtown, Reading postcode and house type. We confirm your conservation and Article 4 status, how much rear-extension depth you have under permitted development, and score your odds against live Reading Borough Council decisions.
We measure the original rear wall, floor and eaves levels, side and rear boundary distances and the neighbours' window positions — the numbers the depth limit and daylight splays depend on.
Chartered designers develop the single or two-storey rear extension to your brief, drawn inside the permitted-development limits or to Reading Borough Council's extension design guidance, with the daylight angles shown.
We submit the certificate, prior-approval notice or application, handle validation and case-officer queries, and revise the drawings free until Reading Borough Council issues its decision.
Often not. A single-storey rear extension up to 3 metres deep on a terrace or semi, or 4 metres on a detached house, and no higher than 4 metres, is usually permitted development in Newtown, Reading. You will need to involve Reading Borough Council for anything deeper via the larger-home route, for two-storey rear extensions, and for any rear extension in a conservation area such as Eldon Square and Alexandra Road, where those permitted-development rights fall away.
The larger-home extension scheme lets a single-storey rear extension reach 6 metres on a terrace or semi, or 8 metres on a detached house — double the standard allowance. It is not automatic: you submit a prior-approval notification to Reading Borough Council, neighbours are consulted, and if one objects on amenity grounds the council rules on it. It also does not apply on designated land such as Newtown, Reading's conservation areas.
It is the daylight test Reading Borough Council applies to protect neighbours. Drawn on plan, a line at 45 degrees from the midpoint of the neighbour's nearest ground-floor window should not be crossed by your extension; a companion 25-degree line is checked in section. If the projection breaches it, the extension is likely to be shortened or refused, so we test and prove it on the drawings before submission. This applies to your Newtown, Reading address specifically.
A two-storey rear extension almost always needs a full householder application to Reading Borough Council, as it sits outside permitted development on most homes. The council checks that it stays at least 7 metres from the rear boundary, does not overbear the neighbours and avoids new overlooking. We resolve the boundary gap, privacy and daylight on the plans so the application is decided on its merits. This applies to your Newtown, Reading address specifically.
Frequently, yes. If the rear extension involves work to a shared wall, building up to the boundary, or excavating foundations near a neighbour's structure, the Party Wall etc. Act applies and you must serve notice — this is separate from Reading Borough Council's planning decision. We flag it early and can prepare the drawings a party-wall surveyor needs alongside the planning set. This applies to your Newtown, Reading address specifically.
