Build a home for family in your garden in Falmouth

If you have a long or wide garden in Falmouth, 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.

Cornwall 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.

Falmouth: light, access and policy

Cornwall Council will judge a family home against the council’s Local Plan and any guidance it has adopted on garden development and annexes. Some councils spell out how closely an annexe must relate to the main house, such as sharing the drive, garden or parking, and what turns a building into a separate home instead. We read the current policies for your address before design starts, because a scheme drawn to suit the wrong test wastes time and money. Where the position is unclear, the council’s pre-application advice can be worth its fee.

Noon sun in Falmouth on 21 March sits about 40° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.0 m. In December the sun is only about 16° up and shadows stretch much further. Drawn for a garden facing north, where it matters most.

What happens next in Falmouth

The next step is a conversation, by phone or through the form, about your garden in Falmouth 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

  • 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.
  • 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 Falmouth

Is CIL payable on a family home in Falmouth?

Only if Cornwall Council has adopted the Community Infrastructure Levy, which its website will confirm, and we check it for you during the appraisal. Where it applies, self-build and residential annexe exemptions exist, but both must be claimed before work starts and can be withdrawn if the home is sold or let within three years of completion.

How long will building work disrupt my home in Falmouth?

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 Falmouth?

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.

Can you design a home in Falmouth 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 Cornwall 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.
