Build a home for family in your garden in Hampshire

Before anyone draws a plan, it pays to agree as a family what the new building is for. An annexe in Hampshire is usually tied to the main house by a planning condition, while a separate dwelling can be put in a relative’s name, mortgaged and sold later.

That choice changes the planning case, the tax position and how much land you need. We set the two side by side during a free plot appraisal, using what we can see of your plot and the planning context across Hampshire, then visit if it looks viable. On VAT and CIL in particular, get professional tax advice before you commit.

Before you start in Hampshire

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 Hampshire, 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 Hampshire include Basingstoke and Deane Borough Council, East Hampshire District Council, Eastleigh Borough Council, Fareham Borough Council, Gosport Borough Council, Hart District Council, Havant Borough Council, New Forest District Council, Portsmouth City Council, Rushmoor Borough Council, Southampton City Council, Test Valley Borough Council, Winchester City 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 Hampshire

What rules apply to a family home in Hampshire?

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.

Is CIL charged on family homes in Hampshire?

Some councils charge the Community Infrastructure Levy and some don’t, so it depends where your house is. Where it applies, a self-build exemption and an exemption for residential annexes are available, but they must be claimed before work starts on site, together with a commencement notice. We check the position for your address during the free appraisal.

Do you build family homes across all of Hampshire?

Yes, we cover garden plots throughout Hampshire, including in and around Southampton, Portsmouth, Basingstoke and Gosport. 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.
