Build a home for family in your garden in Westhoughton

If you have a long or wide garden in Westhoughton, there may be room for a home where a parent or grown-up child can live close by with their own front door. That might mean an annexe used with your house, or a home that stands alone with permission and paperwork of its own.

Bolton Metropolitan Borough Council decides either way, so the first step is to find out what your plot can realistically carry. Our free plot appraisal covers access, space, privacy and the main planning constraints, and talks through who the home is for, before you spend any money on drawings.

Westhoughton: light, access and policy

How the two households will live together shapes the planning case as much as the drawings do. If your parent will eat with you, share the garden and rely on you day to day, an annexe is the natural fit, and that is what Bolton Metropolitan Borough Council will expect the application to describe. If your son or daughter will run their own home, pay their own bills and perhaps sell up one day, it is a separate dwelling and will be assessed against the council’s Local Plan as a new house. For a family in BL5, we help set that out clearly from the start.

Noon sun in Westhoughton 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.

How we’d take it forward in Westhoughton

The next step is a conversation, by phone or through the form, about your garden in Westhoughton and who the new home is for. We check access, title, the main planning constraints and any CIL position for your address, then tell you whether an annexe, a separate home or neither looks realistic. If neither does, we’ll say so and explain why.

  1. Free plot appraisal

    We look at your plot, access and the planning picture from the desk, talk through who will live in the new home, and visit if it looks viable. There’s no cost and no obligation.

  2. Annexe or separate home

    We set out both routes for your plot, covering what each means for planning, ownership, council tax, CIL and VAT, so you can decide with your family and advisers before design starts.

  3. Planning and approvals

    We prepare and submit the planning application and manage it with the council, which makes the decision. Before work starts, approval under the Building Regulations is in place and any CIL exemption has been claimed.

  4. Build and handover

    We build while you carry on living next door, with access, deliveries and working hours agreed up front. At handover you get the completion certificate and the paperwork you’ll need for council tax, lenders and any VAT claim.

Worth checking early

  • A separate home needs its own garden, parking, bins and access, so it needs more land than an annexe.
  • An annexe tied by planning condition usually can’t be sold or let separately, which limits flexibility later.
  • CIL exemptions are lost if work starts before the claim is made, and can be withdrawn if the home is sold or let within three years.

Questions about garden plots in Westhoughton

Can I build a separate house in my Westhoughton garden for my son or daughter?

Possibly, if the plot can work as a home in its own right. Bolton Metropolitan Borough Council will look at access, parking, garden space for both houses, privacy and the character of the street, as it would for any new house. If permission is granted, the plot can be transferred to your child with its own title, with your lender’s consent if the house is mortgaged.

Who owns an annexe built in my Westhoughton garden?

You do. An annexe stays on the title of your house and usually carries a planning condition tying it to the main home, so it can’t be transferred to the relative living in it. If a family member is paying towards it, record what they’ve put in and what happens on a sale in a written agreement drawn up by a solicitor.

Do I need planning permission for a granny annexe in Westhoughton?

Yes, almost always for a detached annexe with its own kitchen, bathroom and bedroom. Bolton Metropolitan Borough Council will treat it as accommodation linked to your home and will usually add a condition so it can’t be let or sold separately. A garden building used only as a home office or gym is a different matter, but sleeping and cooking take it beyond those allowances.

How long will building work disrupt my home in Westhoughton?

A single garden home usually takes several months on site, with the noisiest work, such as groundworks, drainage and heavy deliveries, concentrated near the start. We agree working hours, access and parking with you up front, and with the people next door where it affects them, so your household knows what each week will look like.
