Full-Spectrum Construction Services –
From Vision to Handover.At Phathom, we manage every phase of your construction journey—residential, commercial, or mixed-use. Whether you're starting with a sketch or a full plan, our team of skilled designers, engineers, and tradespeople work in harmony to deliver high-quality projects, on time and on budget. We offer everything from site preparation to finishing touches, ensuring seamless delivery from start to finish.
With decades of hands-on experience and a reputation built on trust, we handle all aspects of the build, from civils to mechanical, electrical, and finishing. Our collaborative approach and technical excellence ensure every detail is executed with precision, whether you're building your dream home, scaling up a commercial property, or developing a new housing scheme.
High-Performance Home and Commercial Design Innovation
Phathom offers bespoke architectural and design innovation that enhances energy performance, aesthetic appeal, and long-term value. We integrate smart layouts, passive design principles, and cost-saving construction techniques that work for modern living and working environments alike. Every design is tailored to the needs of real people and real projects—not architectural trends.
Our commercial designs focus on flexibility, flow, and function, helping developers and businesses reduce operational costs and environmental impact. We also specialise in transforming underused spaces into vibrant, future-ready environments through intelligent redesign and efficient construction practices.
Next-Generation Heating and Combustion Technologies
We are actively rethinking how energy is used in buildings and engines. At Phathom, we develop and test innovative heating systems that reduce emissions, lower costs, and maximise efficiency—without compromising user comfort. Whether for homes, commercial spaces or off-grid locations, our systems are designed with performance and sustainability in mind.
Our combustion engine innovations challenge convention. Through improved airflow management, cooling systems, and energy redirection mechanisms, we aim to revolutionise how internal combustion performs in a decarbonising world. These technologies are under development and patent consideration, showing our commitment to long-term impact.
Smart Retrofits, Eco Extensions & Energy Upgrades
Whether you're upgrading a period property or future-proofing a family home, Phathom delivers intelligent retrofit and renovation solutions that bring modern comfort, energy efficiency, and added value. From structural upgrades to full-home remodelling, we ensure every intervention respects the original structure while improving performance, aesthetics, and functionality.
We specialise in eco-friendly extensions, insulated garden rooms, and modern upgrades that reduce energy consumption and enhance quality of life. From design and planning to construction and final handover, we handle every step with care and craftsmanship—blending old and new seamlessly.
Our retrofit services also include the integration of sustainable technologies such as EV car charging points and solar PV systems. These features help homeowners reduce long-term energy costs and increase self-sufficiency, while supporting Ireland’s climate action goals. Whether it’s a rural detached home, a Georgian townhouse, or a semi-detached retrofit, we tailor solutions that deliver real-world results.
Affordable Eco Housing – Designed and Built for Real Needs
We understand the urgency of addressing housing shortages with fast, affordable, and energy-efficient solutions. Phathom offers fully designed and delivered eco homes that are cost-effective, comfortable, and built to meet Ireland’s evolving housing needs. These units are ideal for permanent living, emergency housing, or strategic social housing schemes.
Drawing from practical knowledge in modular systems, site optimisation, and local planning constraints, we’re helping councils, developers, and families realise housing solutions that work now—and into the future. Every unit is designed with long-term sustainability and low maintenance in mind.
Innovation Is in Our DNA – Join Us in Building Better
At Phathom, innovation isn't a bolt-on; it's our foundation. We are a family business rooted in hands-on building experience, but our eyes are firmly fixed on what’s next. From prototype development to full-scale construction, we continuously explore new ways to improve how we design, build, and live.
We’re open to collaboration, partnerships, and co-development across Europe and beyond. If you're an investor, innovator, developer, or policymaker interested in changing how buildings and energy systems work, we’d love to hear from you. Let’s shape the built environment of the future—together.
