Sell Garden Land and Backland in County Down

Can I sell part of my garden for development in County Down?

Selling part of your garden in County Down for a new home can work well, but the details decide it: the width and route of the access, overlooking, trees, drainage and any covenants on your title. Land to Homes gives a free, no-obligation appraisal and tells you plainly if the plot is unlikely to get permission.

What you get in County Down

Trees and ecology checked

Mature gardens can hold protected trees, bats in outbuildings or nesting birds. We check tree preservation orders and conservation area status, and plan any surveys for the right season.

Access comes first

Most garden schemes stand or fall on access. The drive must be wide enough for cars, refuse collection and emergency vehicles, with safe visibility at the road, under the highway authority's design guidance.

Your retained house matters

Selling part of a garden changes the house you keep: outside space, parking, privacy and value. We look at any scheme from your side as well as from the buyer's.

Mortgage lender consent

If your house is mortgaged, the lender's charge usually covers the whole garden. You will normally need the lender to release the part being sold, which your solicitor arranges as part of the sale.

The Northern Irish system, as it applies in County Down

Permission in Principle, an English route, does not apply in Northern Ireland. Instead, landowners near County Down usually seek outline or full planning permission from the council. Developer contributions are agreed under Section 76 of the Planning Act (Northern Ireland) 2011, and there is no Community Infrastructure Levy. Land to Homes can take on that process through an option or promotion agreement, or buy a suitable site directly, subject to survey, title and contract.

In Northern Ireland, garden and backland schemes in residential areas are judged against council policy and, where still applied, the addendum to PPS 7 on safeguarding the character of established residential areas, alongside the Creating Places design guide. Councils look closely at density, plot size and access. Stamp Duty Land Tax applies on the sale.

Sell Garden Land and Backland in County Down: questions

What is backland development?

Backland development means building homes on land behind an existing row of houses, usually reached by a new access running between them. Many councils have specific policy on it, focused on access, privacy, the character of the area and avoiding piecemeal schemes that would block a better-planned layout later.

Will selling part of my garden affect the value of my house?

It can. A smaller garden, a new drive alongside your home or a new neighbour closer to your boundary may reduce its value, even though the sale brings in money. A local estate agent can advise on the effect on your house, so you can weigh the two together before deciding.

Can I sell part of my garden to a developer?

Yes, if the land can support a new home with safe access and acceptable impact on neighbours. The land is split from your title and sold with rights of way and services set out in the transfer. If your house is mortgaged, your lender will need to consent and release the part being sold.

Should I team up with my neighbours to sell garden land?

Often it helps. Several gardens together can support a better-planned scheme with one shared access, which councils tend to prefer to separate plots. A collaboration agreement sets out how proceeds are shared, usually by area, so no one loses out because of where the access road happens to go.

Do you work with landowners in County Down?

We do. We work with landowners across County Down, including Newry, Castlereagh and Bangor (County Down). Send us a postcode and we will start with a free, no-obligation appraisal of what the land could take.
