Build a home for family in your garden in Grantham

Bringing an elderly parent to live beside you in Grantham often feels like the obvious answer, until you look at what the house can offer. A spare room up a flight of stairs rarely suits someone whose mobility is failing. A purpose-built single-storey home in the garden can.

We offer design and build of garden homes for family across Lincolnshire, with no steps to climb, a bedroom at ground level and a walk-in shower built in from day one. Planning goes through South Kesteven District Council, and we prepare and manage the application for you. Start with a free plot appraisal and we’ll tell you honestly whether your garden looks suitable.

Grantham: light, access and policy

A measured survey is where a family home in Grantham stops being an idea and becomes a plan. We record boundaries, levels, trees, drains and the windows of your house and the houses next door, then test where the new building can sit. With the spring equinox sun standing near 37° at midday here, a 5 m eaves line throws a noon shadow close to 6.6 m; drawing that onto the survey shows which positions keep light in the main rooms of both homes. South Kesteven District Council will expect to see the same evidence with the application.

Noon sun in Grantham 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.

How we’d take it forward in Grantham

The next step is a conversation, by phone or through the form, about your garden in Grantham 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. Survey and design

    A measured survey, then a design built around the person moving in: step-free routes, a ground-floor bedroom if needed and privacy for both households. You get a written quote after design and survey.

  4. 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.

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.
  • VAT savings available on a separate dwelling often don’t apply to an annexe; take advice from a tax adviser before choosing.

Questions about garden plots in Grantham

How much garden do I need for a family home in Grantham?

There’s no fixed figure. A single-storey annexe close to the house can work on a smaller plot than a separate dwelling, which needs its own garden, parking and access. What matters is whether South Kesteven District Council can be satisfied on privacy, daylight and the space left for both homes. The free appraisal gives you a first view based on your plot’s actual shape and access.

Who owns an annexe built in my Grantham 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.

How long will building work disrupt my home in Grantham?

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.

Can I reclaim VAT on a family annexe in Grantham?

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.
