Building on a corner plot or side garden in Windsor

Some homeowners only realise their side garden might be a building plot when a neighbour builds on theirs. Whether yours in Windsor could follow depends on its width, how houses are spaced along the road and whether a new drive would be safe, not just on how much spare land you have.

We look at all of that for free. If the plot works, you might sell it outright, sell it subject to planning or grant an option. Or you might keep it and have a home built, perhaps for a relative who wants to live next door rather than with you.

What the council will look at in Windsor

A new home beside yours affects light to your side windows and your neighbour’s. Around the spring equinox, the noon sun over Windsor climbs to roughly 39°, and a 5 m eaves line then casts a shadow close to 6.3 m long. By December the midday sun reaches only about 15°, so the same wall shades far more ground.

On a side plot that shadow may fall across your own flank wall or the neighbour’s garden. We model it for your actual plot, and adjust the footprint, roof shape or gap at the side so the new home doesn’t take more light than it should.

This section is worked out for the latitude of Windsor: around 39° 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

After you contact us about a side or corner plot in Windsor, we start with a desktop check: maps, the title plan, street views and nearby planning history. We then call to talk through what you want. If the plot looks viable, we visit, measure the street and check the drive position. You get a plain summary of the options, with no obligation.

  1. Free plot appraisal

    We look at your plot on maps, the title plan and street views, check planning history nearby and talk it through with you. If a home beside yours looks possible we visit. No cost, no obligation.

  2. Choose your route

    Sell the plot outright, sell it subject to planning, or grant an option while you keep your house. Or keep the land and have us design, get planning for and build a new home on it.

  3. Design and planning

    We draw a home that sits in the street rather than fighting it, usually take pre-application advice, and submit the application. The council consults neighbours and decides; small schemes often take a few months.

  4. Sale or build

    For a sale, your solicitor handles the transfer of part and any release from your lender. For a build, a written quote follows design and survey, then we build, arrange the warranty and hand over.

Worth checking early

  • A new drive close to a junction may not be acceptable to the highway authority, which can force a different layout.
  • Corners kept open by design can be harder to build on than they look; character can matter more than space.
  • The council decides, and neighbours are consulted; a sensible design can still be refused or need changes.

Your questions, answered for Windsor

Could I sell just my side garden in Windsor and stay put?

Yes. Legally it’s a transfer of part: HM Land Registry gives the side plot a title of its own, while your house keeps the rest. A mortgage lender has to consent to releasing the plot from its charge. Where the plot suits, we buy with or without planning, subject to survey, title and contract.

Is my Windsor side garden wide enough for a new house?

It depends on how wide homes are in your street, the gaps between them, whether the new home would be attached or detached and what the council’s design guidance says. There’s no single minimum width. We measure your plot and the street as part of a free appraisal.

Can I attach a new home to my house in Windsor?

Yes, where it suits the street, for example on the end of a semi-detached pair. It needs planning permission as a separate home, fire and sound separation under Building Regulations, and possibly a party wall agreement. We check whether attached or detached fits your road better.

Can I build a house on my corner plot in Windsor?

Possibly, if a new home would respect the building lines, keep the corner feeling open enough and allow safe visibility for drivers. It needs planning permission, and the Royal Borough of Windsor and Maidenhead decides. Our free appraisal tells you whether your corner is worth taking further.
