Build a home for family in your garden in March

Bringing an elderly parent to live beside you in March 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 Cambridgeshire, with no steps to climb, a bedroom at ground level and a walk-in shower built in from day one. Planning goes through Fenland 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.

How it plays out in March

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 Fenland District 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 PE15, we help set that out clearly from the start.

This section is worked out for the latitude of March: around 37° of sun at midday in late March and about 14° 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.

How we’d take it forward in March

Getting started in March costs nothing. Send us a few photos of your garden and the way in, or simply call, and we’ll look at the plot from the desk and talk through your family’s plans. If there’s a realistic scheme, we arrange a site visit. Survey and design are quoted in writing before you commit, and the build price follows once the design is settled.

  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

  • 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.
  • VAT savings available on a separate dwelling often don’t apply to an annexe; take advice from a tax adviser before choosing.
  • Planning is the council’s decision, and an annexe is not a way round the rules that apply to a new house.

Questions about garden plots in March

Who owns an annexe built in my March 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.

Can you design a home in March for a relative who uses a wheelchair?

Yes. The design can include a level approach and threshold, turning space in each room, a wet room, wider doors and worktops at a usable height. Where Fenland District Council requires a particular access standard through planning, the design meets it; otherwise it’s your choice how far to go. Input from your relative’s occupational therapist is well worth having.

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

Possibly, if the plot can work as a home in its own right. Fenland 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 March?

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.
