Single Storey Extensions

The most popular type of home extension in Ireland, a single storey rear extension is a versatile and cost-effective way to add a new living space or expand your kitchen to the back of your home.

Side Extensions

A house side extension makes smart use of an underutilised side passage area or garden space, adding significant floor area to your home without eating into your rear garden space.

Kitchen Extensions

A kitchen extension opens up the back of the house, floods the space with natural light, and creates the kind of open-plan kitchen and dining area that transforms daily family life.

Garden Room Extensions

A living room or garden room extension creates a comfortable, light-filled space that connects your home with the outdoors — built to perform year-round in the Irish climate.

Bathroom Extensions

Our team of experts build bathroom and en-suite extensions for homeowners who need an additional bathroom on the ground floor or want to add private facilities to an existing bedroom.

Frequently Asked Questions

Do I need planning permission for a home extension in Ireland?
It depends on the size and nature of the extension. Under Irish planning regulations, certain single-storey rear extensions up to 40 square metres fall under exempted development and do not require a full planning application, subject to conditions. We will advise you on what applies to your specific project during the initial consultation.

Yes. We supply and manage every trade your extension requires – plumbers, electricians, plasterers, carpenters & more! So you have one point of contact and one team responsible for the entire project from start to finish.

Yes, and we do this regularly. We take care to minimise disruption to your daily life throughout the build and will discuss upfront how each stage of construction will affect different areas of your home.

Yes. Because roofing is our core trade, flat roof extensions are an area where we genuinely excel, you get a specialist roofing team and an experienced extension builder in one, something most contractors cannot offer.


 

Absolutely. We regularly build extensions that incorporate new bathrooms, en-suites, and accessible wet rooms, supplying all plumbing, electrical, and finishing trades as part of our complete start-to-finish service.
