Intro – Creating More Space Without Moving
Extending your home can transform how you live — whether you’re adding a light-filled kitchen, a playroom, or extra bedrooms. In Galway’s housing market, extending is often more practical than relocating.
At McNena Construction, we’ve been helping homeowners realise their plans since 1977. Here’s what you need to know before you start.
Understand Planning & Building Regulations
Do you need planning permission?
Smaller extensions may qualify as exempt developments, but location, footprint, and height restrictions apply. Always confirm details with Galway City or County Council before work begins.
Building Control compliance (BCAR):
All extensions must meet Irish Building Regulations covering structure, insulation, ventilation, and fire safety.
McNena Construction works directly with architects and assigned certifiers to ensure every stage is documented and compliant.
Budget & Cost Planning
Every property is different, but typical cost factors include:
- Foundations and ground-works
- Structural steel and roof integration
- Plumbing, electrics, and heating
- Finishes and joinery
Allow a contingency for older homes or site constraints.
McNena Construction provides fixed-price contracts outlining every item from start to finish — so you know exactly what you’re investing in.
Designing Your Extension
A successful extension complements your existing home while adding comfort and value.
Our design partners focus on:
