Build a home for family in your garden in Sleaford

Two households, one plot: that’s the idea behind a family home in a Sleaford garden. Done well, each has privacy and a front door, yet help is a few steps away. Done badly, it can strain relationships and leave a building nobody can use when circumstances change.

The difference lies mostly in the planning route and the layout. Backland Development is a new S&K Group brand offering design and build to homeowners in Sleaford and the surrounding area, and each project begins with a free plot appraisal that weighs an annexe against a separate home for your family.

Sleaford: light, access and policy

Access usually decides what a Sleaford garden can take. An annexe can often share your drive because it is used with the house, but a separate home needs an access North Kesteven District Council will accept for a dwelling in its own right, with room for cars, bin collection and emergency vehicles. We cover homes in Sleaford and around Grantham, Boston and Lincoln, and on every plot we measure the drive width, the view along the road where the access joins it, and how far bins would need to travel, before anyone draws a plan.

Noon sun in Sleaford on 21 March sits about 37° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.6 m. In December the sun is only about 14° up and shadows stretch much further. Drawn for a garden facing north, where it matters most.

What happens next in Sleaford

Here’s what happens next for a family home in Sleaford. You tell us about your plot and who the home is for, and we carry out a free desktop appraisal of access, space and the planning context. If it looks viable we visit, then set out the annexe and separate-home options. With your go-ahead we survey, design and give you a written quote, then prepare the application for North Kesteven District Council.

  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

  • VAT savings available on a separate dwelling often don’t apply to an annexe; take advice from a tax adviser before choosing.
  • Family plans change: agree ownership, costs and what happens if circumstances change in writing, with a solicitor.
  • A separate home needs its own garden, parking, bins and access, so it needs more land than an annexe.

Your questions, answered for Sleaford

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

Possibly, if the plot can work as a home in its own right. North Kesteven District 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.

Can I reclaim VAT on a family annexe in Sleaford?

Often not. HMRC’s guidance gives an annexe that can’t be used or sold separately from the main house as an example of work that can’t be zero-rated, and the DIY housebuilders refund scheme asks the same question. A separate dwelling is usually treated differently. Take advice from a tax adviser before you settle the planning route, because the wording of the permission matters.

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

Yes, almost always for a detached annexe with its own kitchen, bathroom and bedroom. North Kesteven District 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.

Who owns an annexe built in my Sleaford 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.
