Building on a corner plot or side garden in Blackburn

A wide side garden or double driveway beside a Blackburn 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 Blackburn with Darwen 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 Blackburn

Take a walk round the junctions near you, in Blackburn and in Darwen, Accrington and Haslingden. 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 Blackburn with Darwen Borough Council has adopted. Reading both before we draw means the scheme already answers the points an officer is likely to raise.

Noon sun in Blackburn on 21 March sits about 36° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.8 m. In December the sun is only about 13° up and shadows stretch much further. Drawn for a garden facing north, where it matters most.

From first call to decision

An enquiry about a side plot in Blackburn can begin with a quick call and a couple of photos of the side of your house and the street. We follow up with a desktop appraisal and, if it’s promising, a site visit. If you sell, heads of terms come next and your solicitor takes over. If you build, we move to survey and design, then a written quote.

  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. 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.
  • 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 Blackburn

Which body approves a new home on a side plot in Blackburn?

The planning decision belongs to Blackburn with Darwen 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.

Will a new drive near the corner be allowed in Blackburn?

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 Blackburn 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 you build a home beside my house in Blackburn for my family?

Yes. A home next door can give a parent or grown-up child their own front door while keeping them close. You keep the land; we draw the house, apply for permission, build it and arrange the structural warranty or other cover lenders accept. The written quote comes after design and survey.
