Building in a large rear garden in Hillingdon

Before paying for drawings of a new home in your Hillingdon garden, it helps to know whether the basics stack up. Can a car get in and turn? How far would the new home sit from your back windows and your neighbours’? Would your own house keep a decent garden and somewhere to park?

We answer those questions in a free garden plot appraisal, starting with maps, the title plan and nearby planning history, then a visit if the plot looks viable. You’ll come away knowing whether selling or building makes more sense for you, and what the London Borough of Hillingdon is likely to ask about.

Hillingdon: light, access and policy

Overshadowing is often the deciding issue in a long garden. At midday on 21 March the sun in Hillingdon stands about 38° above the horizon, so a typical two-storey eaves line throws a shadow of roughly 6.3 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.

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 the London Borough of Hillingdon, 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. Measure and test the layout

    We check depth, the width of the way in, levels, trees, drains and what lies behind, then sketch what could realistically fit: one home, two, or nothing worth pursuing, before anyone pays for an application.

  3. 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.

  4. 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.

Worth checking early

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

Questions about garden plots in Hillingdon

How do I find out if my Hillingdon 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.

Does it cost anything to have my Hillingdon 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 you build a home for my family in my garden in Hillingdon?

Yes. If you keep the land, we can design the home, apply for planning permission, build it once permission is granted and arrange the structural warranty lenders usually expect. You receive a written quote after design and survey. If the home is for a relative who will share your kitchen and front door, an annexe may suit better.

How long does planning take for a garden home in Hillingdon?

It varies. Small schemes often take a few months from submission to decision, and longer if surveys, amendments or extra consultation are needed. Pre-application advice and early surveys add time at the start but can save time later. We won’t promise a date, because the council sets the pace.
