Homes in County Antrim

Across Northern Ireland you find city terraces, suburban semis and rural bungalows and farmhouses, so the right approach depends on the plot and the planning history.

What do you get with a wraparound extension?

A wraparound extension combines a side return and a rear extension into one L-shaped build, giving the biggest possible ground-floor space on terraced and semi-detached houses. It usually creates a large open-plan kitchen, dining and living area across the back of the house.

How much should I budget for a wraparound extension?

What wraparound extensions typically cost. These are guide ranges; the written quote for your house replaces them.

Wraparound extensions	Guide price incl. VAT
Standard specification	£3,400 to £3,800 per m²
Good specification	£3,800 to £4,250 per m²

What approvals does a wraparound extension need in Northern Ireland?

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.
