About

Who we are

Founded by Ned Thwaites, Terra is the culmination of a lifelong curiosity in the built environment and years of experience working in construction and development across the residential and commercial sectors.

Grounded by a respect for our clients’ individual needs and a pursuit for excellence, we pride ourselves on our ability to foster authentic relationships and communicate effectively, ensuring each project is delivered with a superior level of care and rigour.
