The Quantum Group is a new-generation developer offering the Irish property sector a unique blend of experience, innovation and end-to-end build-out service. Our developments aim to answer Ireland's acute need for high-quality real estate, in places and within communities that people want to live.

With over 30 years’ operational experience in the property sector, we have a long history of using innovation to drive property standards in Ireland. At Quantum, our full-service approach is poised to create communities and deliver sustainable developments that ensure the highest quality product at every stage of the process.

Our Mission

We are defined by our heritage to take a partner and people-centred approach to invest, design and develop quality real-estate solutions to empower diverse communities.

About Us

Led by father and son Miceál Sammon and Miceál Anthony Sammon, Quantum brings a wealth of experience to today’s Irish property sector.

Our heritage as a large-scale constructor of social infrastructure and communities has led us to assemble together some of Ireland’s most innovative, forward-thinking and talented professionals to form Quantum, a unique full-service developer with the in-house construction teams and experience to control every aspect of the build, from planning through to construction.

About Us

Our Difference

Our decades of experience in building communities and completing every type of project, from large social infrastructure to bespoke housing developments, have given us a clear vision for the Quantum Group.

We are aware of the responsibility of Irish developers to answer Ireland’s urgent need for quality property and, most importantly, sustainable communities that people want to live and work in. Our difference is our people. We are actively growing and building our landbank with a mixture of sites around Ireland, both with and without planning permission. This growing landbank helps us achieve our aim to develop and provide to the market a range of high-quality developments, including homes for first time buyers in towns and communities that need those valuable residential additions.

Our People

Building Communities

With our residential developments, our ambition is to create communities people want to live in.

Our attention to the planning process, energy efficiency, sustainability and the needs of the end user at all times make our developments attractive, practical, sustainable and simply great places to live and work. All our residential developments are located on carefully selected sites to ensure that the new development enhance and build upon the existing neighbourhood, with amenities and transport links to suit every member of the community, new and old.

Building Communities

Our Developments

Our impressive land bank is growing by the week, and we currently have several New Home schemes underway across the country, with up to 150 units per development.

And with residential sites planned for Waterford, Dublin, Louth and Tipperary, among others, we are well on our way in our ambition to reach 500 homes built per year within the next five years

Our Developments


Through its precisely defined vision, the Quantum Group promotes an extensive commercial build experience, garnered over decades within the international construction industry through vast numbers of successful projects.

Now, with the Group’s integration of an in-house construction arm, Quantum now offers the build-out capability for large-scale commercial builds in Ireland and abroad, in addition to its ambitions of becoming a leading residential developer for the Irish market.
