Who will I be in touch with?

Our leadership team is ready to assist you with your home construction enquiry, see their details below!

Ken O'Callaghan
Director

Ken manages the behind-the-scenes side of every project, working closely with quantity surveyors, architects, engineers, and clients to ensure everything is ready before building begins. Raised on-site alongside his father Dave, Ken originally trained as a solicitor before returning to his true passion - building homes with precision, care, and a hands-on approach to project management.

Mark O'Callaghan
Director

Mark leads the hands-on side of every project, managing construction on-site from the moment work begins. Growing up learning the trade with his father Dave, Mark later honed his skills in plumbing and carpentry while working in Australia before returning home. Today, he brings practical expertise, craftsmanship, and a dedication to building homes that stand the test of time.
