Build a home for family in your garden in Surrey

Building a home for a parent or grown-up child in your garden in Surrey 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 Surrey, including homes in and around Woking, Guildford, Esher and Redhill. 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.

Before you start in Surrey

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 Surrey, 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 Surrey include Elmbridge Borough Council, Epsom and Ewell Borough Council, Guildford Borough Council, Mole Valley District Council, Reigate and Banstead Borough Council, Runnymede Borough Council, Spelthorne Borough Council, Surrey Heath Borough Council, Tandridge District Council, Waverley Borough Council, Woking 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 Surrey

Do councils in Surrey allow annexes for elderly parents?

They can, where the annexe is clearly linked to the main house and the plot can take it without harming neighbours or the character of the area. Each council decides its own applications against its local policies, so what is acceptable on one street may not be on another. Councils covering Surrey include Elmbridge Borough Council, Epsom and Ewell Borough Council, Guildford Borough Council, Mole Valley District Council, Reigate and Banstead Borough Council and other councils.

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

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.

What rules apply to a family home in Surrey?

National policy in England sets the framework through the National Planning Policy Framework (NPPF). Each council then applies its own Local Plan policies, along with the council’s design guide or supplementary planning document where relevant. The building must also meet the Building Regulations, and you need to plan for fire engine access (or other measures, often sprinklers, agreed with building control and the fire service where a fire engine can’t get close enough). If the home is for an older relative, it is worth designing to a higher access standard from the start.

Can neighbours in Surrey combine their gardens?

Yes. Putting two or more adjoining back gardens together can allow one shared access and a better layout than separate plots. Each owner keeps their house. The owners usually sign a collaboration agreement, with an equalisation clause so that value is shared fairly even though only one garden provides the access. Each household should take its own legal advice.
