Sell Garden Land and Backland in Castlereagh

Can I sell part of my garden for development in Castlereagh?

Garden land and backland in Castlereagh means plots taken from large gardens or land sitting behind existing houses, often with no road frontage of its own. It can take one home or a small group, but only if there is safe access and the new homes would not harm neighbours' privacy or the character of the street. We assess both first.

What we offer in Castlereagh

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.

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.

Covenants and title

Older titles often include restrictive covenants limiting building. Depending on the nation and the facts, a release, indemnity insurance or an application to modify the covenant may be possible.

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 Castlereagh

In Northern Ireland, planning applications for new homes around Castlereagh are decided by the local district council, one of 11, while the Department for Infrastructure decides regionally significant schemes. Councils apply the Strategic Planning Policy Statement and their Local Development Plan, together with retained planning policy statements until their Plan Strategy is adopted. Land to Homes offers a free site appraisal and can buy suitable land directly or promote it through planning.

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.

Common questions in Castlereagh

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 I pay Capital Gains Tax when I sell garden land?

Possibly. Private Residence Relief can cover part of a garden in some circumstances, but the size of the garden and the order and timing of sales can affect it. Selling the garden after you have sold the house, for example, may change the position. Speak to an accountant before agreeing terms.

How wide does an access drive need to be for a new house?

There is no single figure for the whole UK. The local highway authority's design guidance sets widths for private drives, passing places and visibility at the junction, and building regulations cover access for fire service vehicles. We check the standards your council applies before estimating what a plot could take.

What is tandem development?

Tandem development is a new house placed directly behind an existing one, sharing or running alongside the same access. Councils often resist it because of noise and disturbance from cars passing the front house and overlooking between the two. A wider plot with its own access is usually viewed more positively.

Is Castlereagh an area you cover for land?

Yes, we cover land in Castlereagh and elsewhere in County Down, including Newtownards, Newry and Bangor (County Down). Where a site suits us we can buy it directly, or set up an option or promotion agreement. On promotion there is nothing to pay upfront.
