New Build Homes in Mayo
Building a new home is one of the biggest projects you’ll ever undertake, and having an experienced, reliable builder by your side makes all the difference. Holmes Building Services has delivered countless new build homes across Mayo, combining strong foundations, energy efficiency, and modern design. We work closely with you to understand your vision, manage every stage of the build, and ensure the final result exceeds expectations.
Whether it’s a contemporary house, a traditional bungalow, or a family home, we bring a balance of practicality and craftsmanship to every project. With over 40 years in construction, we know what it takes to get a build right — from planning through to the finishing touches.
Home Extensions & Renovations
If you need more space without moving house, a home extension is the perfect solution. We specialise in house extensions in Mayo, creating bright, functional, and seamlessly integrated spaces. From kitchen extensions and bathroom upgrades to full-scale renovations, we ensure your home feels modern, comfortable, and built to last.
Our team takes care of the entire process — from foundations and roofing to interior finishes — so you don’t have to juggle multiple contractors. Whether you’re looking to add value, improve energy efficiency, or simply enjoy more room, we’ll deliver an extension tailored to your needs.
Attic & Garage Conversions
Conversions are a cost-effective way to make the most of your property’s existing footprint. We offer expert attic conversions in Mayo, turning unused roof space into bedrooms, offices, or playrooms. Similarly, our garage conversions give you the flexibility to create a gym, utility room, or even a home studio.
We ensure that every conversion is safe, structurally sound, and compliant with building regulations, while also maximising natural light and comfort. For homeowners looking to unlock hidden potential, a conversion is often the smartest investment.
Outdoor & Structural Work
Your outdoor space is just as important as the inside of your home, and we offer a wide range of services to transform it. From patio and driveway installations to garden walls, fencing, and outdoor buildings, we bring durability and style to every project. We also construct conservatories, sunrooms, garages, and agricultural sheds, giving you practical solutions for both home and farm.
We pride ourselves on building outdoor structures that last — from the concrete foundations up. Whether you want to create a new outdoor living area, improve your property’s kerb appeal, or invest in functional farm buildings, our team is ready to help.

When you need conduits or pipework installed without digging up driveways, patios, or roads, trenchless digging (moling) is the answer. This efficient method allows us to bore pathways underground with minimal disruption to the surface, saving time and costly reinstatement work.
