About us

A reputation for results.

Sandymark is the trusted partner of choice for companies and institutional investors seeking sustainable warehousing, manufacturing and logistics property in Ireland.

Our agility and impressive knowledge of industrial real estate have enabled us to identify opportunities in strategic locations, unlocking value through development. We transform greenfield sites into valuable assets that attract blue-chip tenants from diverse sectors.

Based in Rathcoole, Co. Dublin, Sandymark built Ireland’s largest light industrial campus spanning 600 acres at Greenogue Business Park, Greenogue Logistics Park and adjoining Aerodrome Business Park, where over 450 companies enjoy exemplary facilities.

Acknowledged as the country’s first enterprise centre in the 1970s, Managing Director Con McCarthy repurposed it in the early 2000s, creating a futureproofed campus with green industrial units for operations of any size.
