Building on a corner plot or side garden in Sunbury-on-Thames

A wide side garden or double driveway beside a Sunbury-on-Thames house is one of the more straightforward places to add a home, because the new house can line up with its neighbours and have its own drive. It still needs planning permission, and Spelthorne Borough Council will judge how it sits in the street.

Our free appraisal looks at width, the gaps between houses, side windows, parking and what lies under the ground. Then we explain both routes in plain terms: selling the land while you stay put, or keeping it and having a new home designed and built for you.

How it plays out in Sunbury-on-Thames

A new home beside yours affects light to your side windows and your neighbour’s. Around the spring equinox, the noon sun over Sunbury-on-Thames 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.

What happens next in Sunbury-on-Thames

After you contact us about a side or corner plot in Sunbury-on-Thames, 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. Read the street

    We measure the plot and record the building line, the gaps between houses, roof heights, materials and boundary walls, then check where a new drive could go and what drivers would be able to see from 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

  • The council decides, and neighbours are consulted; a sensible design can still be refused or need changes.
  • A new drive close to a junction may not be acceptable to the highway authority, which can force a different layout.
  • Losing a side garden or drive changes how your house works day to day, from parking to getting bins round the back.

Sunbury-on-Thames: questions to ask

Will a new drive near the corner be allowed in Sunbury-on-Thames?

Only if drivers would have a clear enough view of the road and the junction stays safe. The highway authority comments on this and controls new dropped kerbs. Drives very close to a corner are often resisted, so we check the position on site before designing.

Could I sell just my side garden in Sunbury-on-Thames 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.

Which body approves a new home on a side plot in Sunbury-on-Thames?

The planning decision belongs to Spelthorne Borough Council. It checks the proposal against the council’s Local Plan, national policy and its own design guidance, and asks neighbours and the highway authority for their views first. Our role is to prepare and submit a strong application; approval or refusal is the council’s call alone.

Can I attach a new home to my house in Sunbury-on-Thames?

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.
