Building on a corner plot or side garden in Amersham

Some homeowners only realise their side garden might be a building plot when a neighbour builds on theirs. Whether yours in Amersham 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.

Before you decide in Amersham

Light is a real test on side plots because the new home sits so close to existing ones. In midwinter the noon sun in Amersham is only around 15° above the horizon, so even a modest roof can shade a neighbour’s side windows or garden for long periods.

Councils, including Buckinghamshire Council, look at daylight and sunlight to existing homes when deciding applications. A lower eaves line, a hipped roof or a slightly wider gap at the side can make the difference, and we test those options before the drawings are finalised.

Noon sun in Amersham on 21 March sits about 38° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.3 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.

From first call to decision

Give us your Amersham address and a sense of what you’re hoping for. Our desktop review covers the policies Buckinghamshire Council works to, recent applications on nearby side and corner plots, and anything in your title that might restrict building. A clear result leads to a visit when it suits you, after which we explain each route and what it would mean in practice.

  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

  • Attaching a home to yours brings party wall, fire and sound separation work, and changes the feel of your own house.
  • Corners kept open by design can be harder to build on than they look; character can matter more than space.
  • Losing a side garden or drive changes how your house works day to day, from parking to getting bins round the back.

Amersham: questions to ask

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

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 Buckinghamshire Council decides. Our free appraisal tells you whether your corner is worth taking further.

Could I sell just my side garden in Amersham 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 Amersham 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 Amersham?

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.
