Our Process

A well designed and built project adds and maintains the assets value. This is one of our fundamental principles and why we focus a lot on the design process. We manage the build process through systems we have developed over many years and long term relationships we have developed with some of Brisbane’s leading subcontractors and consultants. 


Development planning involves working with councils and town planning consultants to ensure our projects work synergistically with local planning schemes.


Working with leading architectural firms ensures our clients are exposed to leading design principles and are at the forefront of architectural trends.


With both directors licenced open class QBCC Builers, we are able to implement strict processes and controls to ensure that quality is at the forefront of every building project. 

Partners & consultants

They say ‘it takes a village’. To ensure that each development is nothing less than spectacular, JAM Group engages leading experts in every field, from structural engineering, town planning, architecture, civil engineering, marketing and accounting to name a few!
