Single-storey, double-storey, rear and side extension drawings for Woughton homes — measured to Milton Keynes City Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
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.
Woughton homes come in a handful of recurring shapes, and each one points to a different extension. 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, so a Victorian terrace usually wants a rear or side-return infill, while an interwar semi has room for a wider single-storey wrap or a two-storey side addition. Milton Keynes City Council judges every one of them against Plan:MK (the Milton Keynes Local Plan 2019), weighing footprint, height and the impact on the house next door before it looks at the elevations.
That is why the drawings decide the outcome. We set the extension depth against the permitted-development limits precisely, keep the eaves and ridge within the allowances, and plot the 45-degree daylight lines to the neighbours' windows so the case officer can see the amenity test is passed. The New Town's grid-road and linear-park design code shapes plot layout, boundary treatments and landscape setting across the grid squares, so we design around it from the first sketch rather than discover it at validation.
Woughton also protects whole streets — Woughton-on-the-Green, Milton Keynes Village, Willen and Broughton among them. 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. On designated land the larger-home extension route and most side extensions stop being permitted development, so we confirm your address against those layers before drawing a line.
Plenty of Woughton extensions are permitted development and need no planning application — a single-storey rear extension within the depth and height limits is the common case. You will normally need to apply to Milton Keynes City Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships Milton Keynes City Council's officers weigh first — and submit a validation-complete pack, whether that is a lawful development certificate, a prior-approval notification or a full householder application.
Below is Milton Keynes City Council's real householder decision record, drawn 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. A complete, policy-literate extension pack anticipates those pressure points before submission, which is why professionally drawn applications are decided faster and refused less often than DIY ones.

Across Woughton on the Green, Milton Keynes Village and Willen, the extension that lands most often is the single-storey rear addition — a glazed kitchen-diner across the back of the house, kept within the permitted-development depth or taken to a full application where the ground floor wants more. On the borough's historic village cores of stone and brick cottages absorbed into the new town grid, a side-return infill frequently pairs with it to square off the plan; on wider later low-density family housing across the grid squares, a two-storey side or rear extension can add a bedroom above without swallowing the garden.
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 size the extension to the amenity and daylight tests, match the roof and materials to the host house, and keep enough garden to satisfy Milton Keynes City Council's space standards — so the scheme answers the borough's questions before an objection can raise them. Where permitted-development rights are used up or removed, we prepare the householder application to the council's extension design guidance instead.
We draw extensions on every street in the borough. A few of the neighbourhoods where Woughton projects come up most often:

The right extension in Woughton depends on your house type and how much garden you can give up. This is how the main options compare on planning route and what they add.
| Extension type | Permitted development? | What it adds | What Milton Keynes City Council checks |
|---|---|---|---|
| Single-storey rear | Often, within 3m/4m depth (6m/8m via prior approval) | Bigger kitchen-diner across the back | Depth, height, neighbour daylight (45°) |
| Side-return infill | Sometimes, if within width and height limits | Squares off an L-shaped ground floor | Width vs the original house, glazing to boundary |
| Two-storey rear/side | No — full application | Extra bedroom or bathroom above | Bulk, overlooking, 7m rear-boundary gap |
| Wraparound (rear + side) | No — full application | Whole-width open-plan ground floor | Combined footprint and garden retained |
Route depends on your street — conservation areas such as Woughton-on-the-Green and Milton Keynes Village and Article 4 directions can remove permitted-development rights.
A fixed process built around how Milton Keynes City Council validates and decides householder extension applications — most drawings are submission-ready within seven days of survey.
Tell us your Woughton postcode and house type. We confirm your conservation and Article 4 status, how much permitted-development depth you have left, and score your odds against live Milton Keynes City Council decisions.
We measure the existing footprint, floor and eaves levels, boundary distances and the neighbours' window positions — the numbers the depth limits and daylight tests depend on.
Chartered designers develop the single-storey, two-storey or side extension to your brief, drawn inside the permitted-development limits or to Milton Keynes City Council's extension design guidance.
We submit the certificate, prior-approval notice or application, manage validation and case-officer queries, and revise the drawings free until Milton Keynes City Council issues its decision.
Not always. 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 apply to Milton Keynes City Council for two-storey extensions, side extensions wider than half the house, anything forward of the front wall, deeper rear extensions under the larger-home prior-approval route, and any extension in a conservation area such as Woughton-on-the-Green and Milton Keynes Village.
Standard permitted development allows 3 metres on a terraced or semi-detached house and 4 metres on a detached one. The larger-home extension scheme can double that to 6 or 8 metres, but it needs a prior-approval notification to Milton Keynes City Council and a neighbour-consultation period, and it does not apply on designated land such as Woughton's conservation areas. We confirm which route your property qualifies for before drawing.
Two-storey and double-storey extensions almost always need a full householder application to Milton Keynes City Council, because they fall outside permitted development on most homes. The council looks closely at bulk, overlooking of neighbours and the 7-metre gap a two-storey rear extension must keep from the rear boundary. We design to those tests and show the daylight and privacy angles on the drawings. This applies to your Woughton address specifically.
A householder planning application in Woughton runs to a statutory eight-week target, a larger-home prior-approval notification to around six weeks including the neighbour-consultation period, and a lawful development certificate to eight weeks. Incomplete submissions stall at validation, so we submit a complete pack and manage officer queries to keep the decision on schedule. Milton Keynes City Council is the decision-maker.
Yes — planning permission and building regulations are separate consents, and almost every extension needs both. Planning governs whether you can build it; building control governs how it is built, covering structure, insulation, drainage and fire safety. We prepare the building-regulations drawings alongside the planning set so Milton Keynes City Council's building control or an approved inspector can sign the work off. This applies to your Woughton address specifically.
Every house and brief is different, so we price each Woughton extension individually and send a fixed, no-obligation quote back within one working day.
