Through our services, we also provide exploratory design services to assist our clients in achieving the best outcome for their project.

Our Story
CalArth began with humble origins, as its owner, Mell Naylor, grew the company as a side venture alongside her main role as a leading Project Manager in an international consultancy business. As first-time parents, CalArth has given us the drive and empowerment to pursue our passion aside from our corporate commitments for providing services in what we enjoy most.

The love we experienced as first-time parents has fuelled our drive to the extent that we decided to name our business after our first child! Caleb Arthur, our passion, our forever love and now our founding member.
