Homes in County Londonderry

Northern Ireland has a high proportion of detached houses and bungalows outside the cities, which often suit side extensions, rear extensions and upward extensions.

What does a wraparound extension involve?

Because it removes two external walls, a wraparound needs careful structural design and a good plan for the corner where the steels meet. We design, apply for any permissions, build and finish the shell, and can fit the kitchen as part of the same contract.

  • Design, planning drawings and structural calculations
  • Steel frame or goalpost for the corner opening
  • Glazing, insulation, plastering and electrics

What is the guide price for a wraparound extension in Coleraine?

Typical ranges for wraparound extensions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.

High specification£4,250 to £4,700 per m²

Do you need permission for a wraparound extension in Coleraine?

Northern Ireland projects need planning clearance and building control approval from the local council. We prepare the applications and agree any work near neighbouring property directly with the neighbours.

In Northern Ireland permitted development is set by the Planning (General Permitted Development) Order (Northern Ireland) 2015, and small single-storey rear extensions can often go ahead without an application. Building control approval from the council is still needed.

What can affect a wraparound extension?

  • The corner steel connection is the critical detail and is designed by a structural engineer.
  • An open-plan space this size needs a heating plan, often underfloor heating.
