Building Excellence Since 1810

Collen Construction is a family owned business established in 1810 with a strong reputation for building quality and excellence.

The company has successfully tendered and negotiated projects for a range of clients including large multi-national corporations, private companies, local authorities and state authorities. We have established a reputation for providing complex projects on time and within budget.

Our dedicated teams work closely with design teams providing a full turn-key service to the client as required. Our management team ensures smooth co-ordination of all aspects of the project including mechanical and electrical services.

Our ability to consistently deliver quality and meet client parameters, has often led to a partnership approach on subsequent projects with the same clients.
