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 does a side return extension involve?

A side return extension builds over the narrow passage that runs beside the back of many Victorian and Edwardian terraced houses, widening the kitchen or dining room by a metre or two. It is usually combined with a glazed or part-glazed roof so the deeper room still gets daylight.

  • Structural steel to remove the side wall
  • Underfloor heating ready screed if wanted
  • Plastering and making good to the old house

Planning and building rules in Portrush

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 should I think about before starting?

  • Access is often through the house, so we plan deliveries and protect floors.
  • Glazed roofs need careful detailing against the neighbour’s wall.

What happens after I enquire?

  1. Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
  2. We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
  3. Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
  4. Construction and completion. One site lead co-ordinates every trade through to the building control certificate.

What people ask before starting

Is a glazed roof too hot in summer?

Modern solar-control glass and a mix of glazed and solid roof keep it comfortable. We advise on the balance during design.

How long does a side return take?

About 10 to 14 weeks on site.

Who deals with the council for a project in Portrush?

We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
