Do you need planning permission for a side return extension in Cookstown?

Planning for a side return extension in Cookstown follows the Northern Irish householder rules.

In Northern Ireland side extensions that face a road, or go beyond permitted development limits, need planning permission from the council, and most wraparounds go through a planning application.

Northern Ireland has no Party Wall Act. Shared-wall work relies on agreement with your neighbour and the general law, so we put access and protection arrangements in writing before starting.

Conservation areas, Areas of Outstanding Natural Beauty and listed buildings restrict permitted development in Northern Ireland. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.

What are homes in Cookstown like to extend?

Semis and detached houses are typical of Cookstown, and many have room for a rear extension within Northern Ireland's permitted development limits.

FAQ

Side return extension questions in Cookstown

Do I need planning permission for a rear extension in Cookstown?

Often not for a single-storey rear extension of up to 3 metres (4 metres detached) under Northern Ireland's permitted development rules, outside conservation areas.

Who will build my extension?

Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.

Can I combine a side return with a rear extension?

Yes; that is a wraparound extension, and it gives the biggest open-plan room a terrace can have.

Is the site visit in Cookstown free?

Yes. We visit, measure up and talk through the options with no cost and no obligation.

How long does a rear extension take to build in Cookstown?

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.

Can I live at home while the extension is built?

Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
