Building in a large rear garden in Blackburn

There are two broad ways to use spare land at the back of a house in Blackburn. The first is to sell it: outright, subject to planning, through an option, or alongside your neighbours. The second is to keep it and have a new home designed, approved and built on it for you.

Which suits you depends on how much risk and involvement you want, and on what the plot can realistically take. A single bungalow, a two-storey home, or a pair sharing one drive across two gardens are all possible on the right site. We look at yours first, free of charge, and explain the trade-offs.

What shapes a plot in Blackburn

Overshadowing is often the deciding issue in a long garden. At midday on 21 March the sun in Blackburn stands about 36° above the horizon, so a typical two-storey eaves line throws a shadow of roughly 6.8 m. In midwinter the noon sun is only about 13° up and shadows stretch around three times as far.

That’s why the gap between a new home and neighbouring gardens matters, and why a lower roof, or a home set further from the boundary, can make a scheme acceptable. We check the shadows on your actual plot rather than relying on rules of thumb.

This section is worked out for the latitude of Blackburn: around 36° of sun at midday in late March and about 13° 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

Once you’ve had the free appraisal, nothing moves without your say-so. For a sale, terms are agreed in writing before you sign anything. For a build, design and survey come first and the quote follows. In both cases the planning application goes to Blackburn with Darwen Borough Council, which consults your neighbours before deciding. Small schemes often take a few months from submission, and surveys or design changes can add more.

  1. Free plot appraisal

    We look at your garden using maps, the title plan and the planning history around you, then talk it through with you. If it looks workable we arrange a site visit. There’s no cost and no obligation.

  2. Measure and test the layout

    We check depth, the width of the way in, levels, trees, drains and what lies behind, then sketch what could realistically fit: one home, two, or nothing worth pursuing, before anyone pays for an application.

  3. Planning application

    We prepare the drawings and reports, usually take pre-application advice, and submit. The council consults neighbours and decides. Small schemes often take a few months from submission, longer if surveys or amendments are needed.

  4. Sale or build

    If you sell, your solicitor handles the transfer of part and your lender’s release of the plot. If you build, we give a written quote after design and survey, then build and hand over the new home.

Worth checking early

  • A covenant, a mortgage, a public sewer or a protected tree can slow a scheme down or stop it altogether.
  • Neighbours are consulted and may object. The council decides, and a carefully designed scheme can still be refused.
  • Cars passing beside your house to reach the new home bring noise and headlights; screening helps but doesn’t remove it.

Your questions, answered for Blackburn

Can I build a house in my back garden in Blackburn?

Possibly, if the garden is deep enough, has a safe way in and a new home wouldn’t harm the neighbours or the character of the street. A new separate home always needs planning permission, and Blackburn with Darwen Borough Council makes the decision. A free appraisal will tell you whether your garden is worth taking further.

Does it cost anything to have my Blackburn garden looked at?

No. The garden plot appraisal is free and carries no obligation. It starts with a desktop check and a conversation, and we arrange a site visit if your garden looks viable. You only commit to anything once you’ve chosen a route and seen the terms in writing.

How long does planning take for a garden home in Blackburn?

It varies. Small schemes often take a few months from submission to decision, and longer if surveys, amendments or extra consultation are needed. Pre-application advice and early surveys add time at the start but can save time later. We won’t promise a date, because the council sets the pace.

Can you build a home for my family in my garden in Blackburn?

Yes. If you keep the land, we can design the home, apply for planning permission, build it once permission is granted and arrange the structural warranty lenders usually expect. You receive a written quote after design and survey. If the home is for a relative who will share your kitchen and front door, an annexe may suit better.
