Build a home for family in your garden in Canterbury

For grown-up children in Canterbury, the step to a first home can be a long one. If your garden is big enough, a small separate house on part of it could become theirs: with its own planning permission and title, it can be mortgaged in their name and sold when they move on.

That asks more of the plot than an annexe does, including its own garden, parking and an access Canterbury City Council will accept. We look at all of that in a free plot appraisal, then design and build the home if the scheme stacks up and you want to go ahead.

How it plays out in Canterbury

Daylight matters twice over when the new home is for a relative who spends much of the day indoors. At noon on 21 March the sun in Canterbury is about 39° above the horizon, so a two-storey eaves line around 5 m high casts a shadow of roughly 6.2 m. A single-storey annexe with eaves at half that height casts one about half as long, which is one reason low buildings often sit more easily in a garden. By late December the midday sun climbs only about 15°, so we test winter light on both homes, and on next-door gardens, before the layout is fixed.

This section is worked out for the latitude of Canterbury: around 39° of sun at midday in late March and about 15° 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.

From first call to decision

Getting started in Canterbury 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. 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.
  • A separate home needs its own garden, parking, bins and access, so it needs more land than an annexe.
  • Family plans change: agree ownership, costs and what happens if circumstances change in writing, with a solicitor.

Questions about garden plots in Canterbury

Can you design a home in Canterbury 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 Canterbury City 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.

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

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 Canterbury City 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.

Is CIL payable on a family home in Canterbury?

Only if Canterbury City 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.

Who owns an annexe built in my Canterbury 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.
