Build a home for family in your garden in Kent

Building a home for a parent or grown-up child in your garden in Kent starts with one choice: should it be an annexe used alongside the main house, or a self-contained home with planning permission of its own and, if you want it, a separate title? Both need a planning application, and the council for your address makes the decision.

We cover Kent, including homes in and around Maidstone, Gillingham, Chatham and Tunbridge Wells. The free plot appraisal looks at your access, the space around the existing house and who the new home is for, then sets out which route is realistic and what each would mean for ownership, council tax, CIL and VAT.

Getting it right in Kent

Under the National Planning Policy Framework (NPPF), councils weigh the character of an area and the effect on neighbours when deciding whether a home can go in a garden, and the council’s Local Plan usually adds local detail. For a family home in Kent, that means the design has to suit its surroundings as well as the relative moving in. Single-storey buildings, careful window placement and boundary planting often help. Many councils use separation distances of around 21 metres between facing back windows, but your council’s own guide decides.

Planning authorities covering Kent include Ashford Borough Council, Canterbury City Council, Dartford Borough Council, Dover District Council, Folkestone and Hythe District Council, Gravesham Borough Council, Maidstone Borough Council, Medway Council, Sevenoaks District Council, Swale Borough Council, Thanet District Council, Tonbridge and Malling Borough Council, Tunbridge Wells Borough Council.

How it works

  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.

  5. 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.

Questions about family home in your garden in Kent

How long does planning take for an annexe in Kent?

Usually a few months from a valid application, though it varies between councils and with how many changes are needed. Applications that draw objections or need extra reports take longer. Pre-application advice adds time at the start but often saves it later by flagging problems before you apply.

Do you build family homes across all of Kent?

Yes, we cover garden plots throughout Kent, including in and around Maidstone, Gillingham, Chatham and Tunbridge Wells. Every enquiry starts with a free desktop appraisal of the plot and the planning context, and we arrange a site visit if the scheme looks viable. Design, planning and build follow only if you decide to go ahead.

Can I build a separate home for my child in Kent?

Yes, where the plot is big enough to function as an independent home and the council grants permission. It needs its own access, garden, parking and bin store, and must not unduly harm neighbours’ privacy or light. Once approved, the plot can be given its own title, so your child can own it and, if they need to, mortgage it.

Do I need my own solicitor to sell a plot in Kent?

Yes, always. Your solicitor checks the contract, deals with the transfer of part at HM Land Registry and asks your mortgage lender to release the plot if the house is mortgaged. On option and promotion agreements we cover your reasonable legal fees, with the cap agreed in heads of terms before work starts.
