Building Quality Assured Homes

QA Developments was founded in 2008 by David and Thelma Ham who established the company with a desire to provide exemplary service to its customers and the residential marketplace. Since then, QA Developments has become a well-respected and established construction company – building high quality investment products across Queensland.

QA utilises the most innovative technology to manage the build process from idea and design concept, through to Council planning, approvals, and construction, to final handover and maintenance management. Our processes and practices ensure the most efficient build process is adopted and we finish the building works as early as possible while maintaining a high quality of finish.
