Build a new home in your garden in Milton Keynes

Building a second home behind your own in Milton Keynes is a construction project with one unusual feature: you live beside the site from the first spade to the last coat of paint. That shapes how we plan it, from the fence that separates your garden on day one to where deliveries park.

The route covers everything between an idea and a finished house. We survey and design, prepare and submit the planning application, arrange Building Regulations approval and the structural warranty, organise new water, drainage and electricity connections, and then build. You keep ownership of the land throughout.

The local picture in Milton Keynes

Wherever your house sits across MK5, MK6, MK8 and MK9, a new home behind it needs water, power and two kinds of drainage — one for waste, one for rain. We contact the utility providers early, because a long cable run, a sewer at the wrong depth or a public pipe under the lawn can change both the layout and the cost.

Rain from the new roof and drive has to be dealt with on site, and Milton Keynes City Council will want to see how. Where a public sewer crosses your garden, the water company may also need a build-over agreement before work starts, so we check sewer records at appraisal stage.

Noon sun in Milton Keynes on 21 March sits about 38° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.4 m. In December the sun is only about 15° up and shadows stretch much further. Drawn for a garden facing north, where it matters most.

How we’d take it forward in Milton Keynes

If your Milton Keynes plot already has planning permission, we begin by checking the approved drawings and conditions against the site. Some permissions need detailed design, discharge of conditions or a minor amendment before they can be built. We then prepare the technical drawings, arrange Building Regulations approval and the warranty, apply for utility connections and give you a written quote to build.

  1. Free plot appraisal

    We check the title plan, access, constraints and planning policy from our desk, talk the plot through with you, and visit if it looks viable. There’s no cost and no obligation.

  2. Survey and design

    A measured survey records levels, boundaries, trees and neighbouring windows. We then design a layout and house that suit the plot, the street and your budget, and decide whether pre-application advice is worth seeking.

  3. Written quote and build

    Once design and survey are complete you get a written quote. The build runs in stages — access and groundworks, foundations, frame and roof, fit-out and external works — with inspections at each key point.

  4. Handover

    You receive the completion certificate, warranty documents, Energy Performance Certificate, manuals and utility details, so the new home is ready to move into, let or put on the market.

Worth checking early

  • A build next door means months of noise, deliveries and contractors near your home; good planning reduces the disruption but doesn’t remove it.
  • You fund the build and carry the cost risk; ground conditions, sewer diversions or supply upgrades found later can move the price.
  • Building and selling a new home can change your tax position compared with selling only your house; take advice from a tax adviser first.

Questions about garden plots in Milton Keynes

How close can a new house be to my own in Milton Keynes?

There’s no single national distance. Many councils use separation guides of around 21 metres between facing back windows and around 12 to 15 metres between a back window and a blank side wall, but the guidance used by Milton Keynes City Council decides. Window positions, ground levels, roof shape and screening all affect what is acceptable, which is why we survey before we design.

How long does planning take for a new home in a Milton Keynes garden?

The statutory period for deciding a minor application, such as a single new home, is 8 weeks from the date the council receives a valid application, in both England and Wales. In practice many applications take longer, and the council may ask you to agree an extension in writing. Surveys and design before submission add time, and conditions may need approving afterwards.

Will I pay Community Infrastructure Levy on a new home in Milton Keynes?

Only if Milton Keynes City Council has adopted a Community Infrastructure Levy charging schedule; not every council has. Where it applies, it can be charged on a new home of any size. A self-build exemption exists for people building a home to live in, but it must be claimed before work starts, so we check the position at design stage.

Do you visit gardens in Milton Keynes before giving advice?

We start with a desk review of the title plan, access, constraints and planning policy, then talk the plot through with you. If it looks viable, we arrange a site visit to see the access, levels, trees and neighbouring windows for ourselves. The appraisal is free and carries no obligation.
