Building on a corner plot or side garden in Welwyn Garden City

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

Take a walk round the junctions near you, in Welwyn Garden City and in Hatfield, Hertford and St Albans. Side gardens that already have a house on them show the kind of thing the council has accepted before, although each new application stands on its own and is judged under today’s policy. A corner that is still open will draw closer attention.

Those local tests are written into the council’s Local Plan and any design guidance Welwyn Hatfield Borough Council has adopted. Reading both before we draw means the scheme already answers the points an officer is likely to raise.

This section is worked out for the latitude of Welwyn Garden City: 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

You stay in control after the appraisal. Selling means heads of terms in writing, read by your solicitor, before anything is signed. Building means survey and design ahead of a written quote. Whichever you choose, Welwyn Hatfield Borough Council receives the application and asks your neighbours for comments, and a decision on a single home often takes a few months, longer if the design needs amending.

  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. 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.

  4. 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.

Worth checking early

  • The council decides, and neighbours are consulted; a sensible design can still be refused or need changes.
  • 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.

Questions about garden plots in Welwyn Garden City

Could I sell just my side garden in Welwyn Garden City 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.

Will a new drive near the corner be allowed in Welwyn Garden City?

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.

Is my Welwyn Garden City 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.

Which body approves a new home on a side plot in Welwyn Garden City?

The planning decision belongs to Welwyn Hatfield 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.
