Back-of-house extension drawings for Woughton homes — the glazed kitchen-diner across the rear, drawn to Milton Keynes City Council's depth and daylight limits, delivered in days and revised free until your decision, with a free approval-odds check first.
Milton Keynes City Council granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. The New Town's grid-road and linear-park design code shapes plot layout, boundary treatments and landscape setting across the grid squares, which is where a policy-literate drawing pack earns its keep. Its mixed housing stock sets the design brief street by street.
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. In conservation areas such as Woughton-on-the-Green, Milton Keynes Village and Willen those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Woughton is determined against an 8-week statutory target.
Woughton on the Green (a historic green-side village and conservation area enclosed by the grid roads), Milton Keynes Village (the ancient village that gave the New Town its name, a conservation area), Willen (a historic village and conservation area beside Willen Lake and the peace pagoda), Broughton (a former village and conservation area on the eastern grid), Woolstone (the paired hamlets of Great and Little Woolstone within the central grid squares) and Springfield (a 1970s grid-square estate close to Central Milton Keynes) — these are the Woughton pockets our drawings cover most. Heritage designations here include Woughton-on-the-Green, Milton Keynes Village, Willen and Broughton. Milton Keynes City Council weighs each proposal against Plan:MK (the Milton Keynes Local Plan 2019), where historic village cores such as Woughton and Milton Keynes Village survive as conservation islands inside the modern grid, with tight controls on their heritage frontages. On roofs the borough is pitched clay-tile and thatch roofs on the village cores and gabled and mono-pitch roofs on the grid-square estates, over historic village cores of stone and brick cottages absorbed into the New Town grid, 1970s and 1980s grid-square estate housing and later low-density family housing across the grid squares.
The rear extension is the workhorse of Woughton home improvement — it is how a dark back kitchen becomes an open family room facing the garden. Because the borough is built largely from historic village cores of stone and brick cottages absorbed into the New Town grid, 1970s and 1980s grid-square estate housing and later low-density family housing across the grid squares, most back walls sit close to a neighbour on at least one side, and that proximity, not the design, is what Milton Keynes City Council scrutinises. The council reads the proposal against Plan:MK (the Milton Keynes 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 New Town's grid-road and linear-park design code shapes plot layout, boundary treatments and landscape setting across the grid squares, so the rear elevation is composed around it rather than corrected after an objection.
Where the property sits in a conservation area — Woughton-on-the-Green, Milton Keynes Village, Willen and Broughton among Woughton's — the larger-home extension route is switched off and even a modest rear addition needs consent. No residential Article 4 direction applies to the central grid villages, so permitted-development rights remain intact outside the conservation areas, while the Woughton-on-the-Green, Milton Keynes Village, Willen and Broughton conservation areas apply standard controls on the historic cores. We confirm the designation before the survey.
Many single-storey rear extensions in Woughton are permitted development and need no application. You will normally need to apply to Milton Keynes City 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 Milton Keynes City 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 Milton Keynes City Council's real householder decision record, taken from official planning statistics and refreshed as new data lands. Milton Keynes approves the large majority of householder applications, with the grid-square design code and the conservation islands of the historic villages the main constraints here. 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 Woughton on the Green, Milton Keynes Village and Willen, 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 historic village cores of stone and brick cottages absorbed into the 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.
Historic village cores such as Woughton and Milton Keynes Village survive as conservation islands inside the modern grid, with tight controls on their heritage frontages. We keep the extension inside the daylight splays, set any glazed roof below the first-floor cill, and retain the garden depth Milton Keynes City 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 Woughton back-of-house projects come up most often:

How far you can extend at the back in Woughton depends on your house type and the route you take. This is how the options compare.
| Route | Depth allowed | Consent needed | What Milton Keynes City 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 Woughton-on-the-Green and Milton Keynes Village and Article 4 streets need a full application.
A fixed process built around how Milton Keynes City Council validates and decides rear-extension applications — most drawings are submission-ready within seven days of survey.
Send us your Woughton 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 Milton Keynes City 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 Milton Keynes City 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 Milton Keynes City 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 Woughton. You will need to involve Milton Keynes City 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 Woughton-on-the-Green and Milton Keynes Village, 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 Milton Keynes City 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 Woughton's conservation areas.
It is the daylight test Milton Keynes City 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 Woughton address specifically.
A two-storey rear extension almost always needs a full householder application to Milton Keynes City 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 Woughton 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 Milton Keynes City 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 Woughton address specifically.
