Who We Are

G5 Special Projects was formed in 2017 following a review of the services provided by Kennett Builders and the identification of a requirement to cater for commercial projects in the range of $10,000 to $5m for both our existing and future clients.

G5 Special Projects is part of the Kennett group and is co-located at their Brompton facility allowing G5 to share corporate services and resources.

G5 Special Projects is focussed on delivering commercial refurbishment and fitout projects. Our management has over 20 years experience in delivering both D&C and traditional build-only contracts in all areas of construction, including retail, health, hospitality, defence, education, residential and industrial projects.
