Build a home for family in your garden in Crowborough

Two households, one plot: that’s the idea behind a family home in a Crowborough 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 Crowborough and the surrounding area, and each project begins with a free plot appraisal that weighs an annexe against a separate home for your family.

Crowborough: light, access and policy

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 Wealden 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 TN6, we help set that out clearly from the start.

Noon sun in Crowborough on 21 March sits about 39° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.2 m. In December the sun is only about 15° up and shadows stretch much further. Drawn for a garden facing north, where it matters most.

From first call to decision

From first call to keys, a family home in Crowborough follows a clear order. Free appraisal and site visit; measured survey and design around the person moving in; a planning application to Wealden District Council; approval under the Building Regulations and any CIL exemption claimed before work starts; then the build, with you living next door throughout. You receive a written quote after design and survey, and we keep the household updated at each stage.

  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

  • Planning is the council’s decision, and an annexe is not a way round the rules that apply to a new house.
  • An annexe tied by planning condition usually can’t be sold or let separately, which limits flexibility later.
  • Family plans change: agree ownership, costs and what happens if circumstances change in writing, with a solicitor.

Crowborough: questions to ask

Who owns an annexe built in my Crowborough 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 much garden do I need for a family home in Crowborough?

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 Wealden 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.

Can you design a home in Crowborough 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 Wealden 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.

Is CIL payable on a family home in Crowborough?

Only if Wealden District 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.
