About Quantum

Quantum is led by father and son Miceál Sammon and Miceál Anthony Sammon, both of whom have immense experience in the sector.

Miceál Sr was previously head of one of Ireland’s largest builders, The Sammon Group, which employed 500 employees in high-profile projects throughout the country, including some of our biggest and most impressive social infrastructure.


Our experience and heritage as a quality large-scale builder has given us a clear vision of Ireland’s urgent need for responsible and sustainable property development – both commercial and residential – that enhance existing communities and build upon the existing fabric of a successful neighbourhood.

We are aware of the challenges that currently face the property sector, and have built up an experienced and talented team with the in-house capabilities to deliver on every aspect of the build process, without fear of delays or unexpected costs due to partner or supply-chain issues.

We place huge emphasis on the build quality, and are proud to have led the way in bringing specialist, innovative techniques to the wider Irish market that push the boundaries in terms of design, cost-effectiveness, construction time and energy efficiency. We think big and we deliver even bigger.
