Who are we

We are a team of dedicated developers and builders based out of the Queensland capital, Brisbane. Our founders have been working together for over 20 years and have worked on several projects. Building and developing sustainable projects is our jam.

The name ‘JAM Group’ arrived with our founders over dinner and is an acronym for ‘Jim And Mick’, or ‘James And Michael’ for those who prefer to use non-abbreviated names.

We have always endeavored to build an enviable product that sells itself. In every case, we have succeeded with happy clients either living in or renting the JAM product. Whether it’s building a townhome, shed, or house, we’ve got you covered!

Our Process

A good project in an area ultimately adds value to the suburb. Our objective is to create value for our clients through good design, increasing site viability, improving land values, creating a better living and built environment. We enjoy what we do and delight in seeing a finished project that works for the client, site, and community.

We collaborate with clients, consultants, and local stakeholders throughout the life of a project. Using our purpose-built software we work in three dimensions from the earliest stages to communicate our ideas/concepts, test our designs, improve coordination and minimize errors.


Development planning is all about ensuring timing, placement and project stars align.


With simplicity at it’s heart, our architects ensure that their designs are future proof.


Having control over the entire process enables us to guarantee a quality build at the end.

Partners & consultants

They say ‘it takes a village’. We work with a number of external consultants to ensure the end product from JAM Group is nothing less than spectacular.
