Building in a large rear garden in Milton Keynes

There are two broad ways to use spare land at the back of a house in Milton Keynes. The first is to sell it: outright, subject to planning, through an option, or alongside your neighbours. The second is to keep it and have a new home designed, approved and built on it for you.

Which suits you depends on how much risk and involvement you want, and on what the plot can realistically take. A single bungalow, a two-storey home, or a pair sharing one drive across two gardens are all possible on the right site. We look at yours first, free of charge, and explain the trade-offs.

Milton Keynes: light, access and policy

Overshadowing is often the deciding issue in a long garden. At midday on 21 March the sun in Milton Keynes stands about 38° above the horizon, so a typical two-storey eaves line throws a shadow of roughly 6.4 m. In midwinter the noon sun is only about 15° up and shadows stretch around three times as far.

That’s why the gap between a new home and neighbouring gardens matters, and why a lower roof, or a home set further from the boundary, can make a scheme acceptable. We check the shadows on your actual plot rather than relying on rules of thumb.

This section is worked out for the latitude of Milton Keynes: around 38° of sun at midday in late March and about 15° at midwinter. It shows why the gap between your house and a new home behind it is about light as well as privacy. Garden assumed to face north.

The next steps, locally

Once you’ve had the free appraisal, nothing moves without your say-so. For a sale, terms are agreed in writing before you sign anything. For a build, design and survey come first and the quote follows. In both cases the planning application goes to Milton Keynes City Council, which consults your neighbours before deciding. Small schemes often take a few months from submission, and surveys or design changes can add more.

  1. Free plot appraisal

    We look at your garden using maps, the title plan and the planning history around you, then talk it through with you. If it looks workable we arrange a site visit. There’s no cost and no obligation.

  2. Choose your route

    You decide whether to sell the plot outright, sell subject to planning, grant an option, team up with neighbours, or keep the land and have us design, get planning for and build a home on it.

  3. Planning application

    We prepare the drawings and reports, usually take pre-application advice, and submit. The council consults neighbours and decides. Small schemes often take a few months from submission, longer if surveys or amendments are needed.

  4. Sale or build

    If you sell, your solicitor handles the transfer of part and your lender’s release of the plot. If you build, we give a written quote after design and survey, then build and hand over the new home.

Worth checking early

  • A shorter garden changes how your own house feels to live in and may affect what it is worth.
  • Surveys and drawings cost money before any decision. On a subject-to-planning sale we normally fund them; on a build you do.
  • Cars passing beside your house to reach the new home bring noise and headlights; screening helps but doesn’t remove it.

Your questions, answered for Milton Keynes

How do I find out if my Milton Keynes garden is big enough for a house?

Ask for a free garden plot appraisal. We measure depth and the width of the way in, check what lies behind, look at levels, trees and drainage, and compare your garden with your council’s separation and garden-size guidance. Size alone rarely settles it, because access and neighbours’ privacy matter just as much.

Who decides planning for a home in a Milton Keynes back garden?

Milton Keynes City Council decides, using the council’s Local Plan, national policy and any local design guidance. It consults neighbours and other bodies before reaching a decision. We prepare the application and deal with the planning officer, but the outcome is always the council’s call.

Does it cost anything to have my Milton Keynes garden looked at?

No. The garden plot appraisal is free and carries no obligation. It starts with a desktop check and a conversation, and we arrange a site visit if your garden looks viable. You only commit to anything once you’ve chosen a route and seen the terms in writing.

Can I build a house in my back garden in Milton Keynes?

Possibly, if the garden is deep enough, has a safe way in and a new home wouldn’t harm the neighbours or the character of the street. A new separate home always needs planning permission, and Milton Keynes City Council makes the decision. A free appraisal will tell you whether your garden is worth taking further.
