We found Supa Group online, and the reviews gave us the confidence to make contact. The designer, Steve, was the nicest person to work with and exemplified our ideas with a design that met our budget, while also improving amenity. When we proceeded with the build, the building team worked well and never cut corners, even while working under Covid restrictions. The new extension not only rejuvenated our old weatherboard house but has also retained it's charm. We would highly recommend the Supa Group for any extension project.

From start to finish the consultation was great. Didn't push us into what they wanted, but actually pointed out how things could be improved as we went through the design process. The build itself was flawless. We engaged our own window, kitchen and floor company, but the coordination from Supa Group was also there. Whilst being our responsibility, they stepped in when needed, to help clarify or direct. Amazing job. We're doing upstairs next with these guys.

Supa Group were fantastic - right from the first visit from Joe. He was well prepared and designed a great extension and renovation of the existing house. Our input and ideas were all accommodated.
Braidon did an excellent job getting all the work happening - despite roadworks, Covid-19 (including the loooong lock-down) and us living in the house with 2 kids and a dog. No request was too much hassle and we never felt like we were just 'another job'. The tradies were professional and polite. The communication with the office was always professional and friendly. If we were to renovate again

We built a second floor extension with Supa Group last year and could not be happier. I had made a website enquiry and was suprised to receive a phone call immediately. A meeting was organised with Joe who was very knowledgeable and quickly identified our needs and launched us into the planning phase. We found Joe to be professional and very approachable with a real joy for his work. After a few months we were finally ready to start our build after meeting our site supervisor Dennis. Dennis was awesome. He dealt with any issues that arose promptly and professionally, and was known to be on our

We contacted Supa Group based on the google review for our second story extension inquiry. We were so lucky to have their designer Ray approached us first. Ray is a professional, talented designer who was able to work within our budget to make a floor plan to meet all our requirements. Thanks Ray for the fantastic job you have done for us - everyone who visited our house loves it! We would like to thank everyone at Supa Group for our second story extension especially our building supervisor Dennis who is hardworking, responsible and great to deal with, Tile layer Morris who did a great job on

Supa Group were great to deal with from start to finish. From the initial visit Joe Caputi listened to what we wanted had some great suggestions. Gerard managed the project brilliantly even with the difficulties of lock down and the entire build (kitchen, bathroom, laundry, study, bedroom, dining area) was wrapped up on time in four and a half months. Our variations during the build were all dealt with quickly and with no fuss by the office and all the trades knew exactly what they were supposed to do. Wonderful job!

I won't hesitate in recommending Supagroup to any home owners who are looking to extend their home or in a quandary on whether to move or extend. Supagroup were incredibly helpful in creating a suitable design which met our specification and Budget. The build was a breeze, we weren't required to move out for any of the build phases and the trades were very professional. Scott was our site supervisor who managed the entire project - Scott was very helpful and onsite most days to keep us informed on the status and so on. From our perspective, the build was successful and hassle free. We are more
