About Sunbuilt Constructions

We builds New Homes, Renovations and Commercial Projects on the Sunshine Coast.

We are not your old-school builder. We are Construction Mangers powered by a patented new business model C2CPRO.

We work alongside clients as Construction Managers under the C2CPRO system, we  provide a Guaranteed Maximum Price with complete builders supervision, insurances and warranties.

You get the best prices possible for all trades and suppliers, any savings are returned to the clients not absorbed by the builder and have a ceiling price to provide security for the client.

We would love the opportunity to speak to you about this unique approach to building and would be pleased to provide you with details of satisfied customers who have used this new approach.

Working with a C2CPRO Construction Manager offers you total transparency, with the service of a skilled builder, added savings and the security of knowing where you money is being spent.

A Client's journey

See how it all comes together with C2CPRO

Our business model is based on becoming a construction manager for your project and is powered by C2CPRO. This patented system includes a building planner module called the Discovery Program.

See how the new way of building can bring savings, security and transparency to your project. See how one of our customers benefited from using our system in all facets of her dream home project.

Leona was able to discover what her budget was going to be, before the final plans or design decisions were made, saving costly budget blow-outs. She was able to make savings by freely shopping around, not restricted to the builder's trade accounts or preferred suppliers.

Our system allowed her, the customer, to pay the trades and suppliers directly (co-ordinated by us), so everything was open and transparent and she knew that there were not secret margins and her money stayed on her project.


We have over 25 years of experience in commercial, civil and domestic projects.

A Transformation Renovation Before and After Photos

A Transformation Renovation Before and After Photos

Our client had bought this old beauty premarket and even though it was extremely dated, could see the potential in this fantastic location on the canal in Pelican Waters, on the Sunshine Coast in Queensland. The client used the C2CPRO building model with Sunbuilt Constructions before any plans were finalised..


Just a few of our happy customers

My husband and I are more than satisfied with the workmanship of Sunbuilt Construction. They reinstated our fascia, soffit & gutters to their original state . A most co-operative and competent group of tradesman's that you would wish to find. We'd highly recommend them to one & all. AvrilMoffat Beach, QLD , Home Renovation
Marcel & team were awesome. We did major renos, and Marcel ensured everything went smoothly. I changed things on fly and Marcel made them happen. The crew were nicest bunch of blokes. Wouldn’t change a thing. House is better than I had hoped. I would highly recommend, in fact wouldnt use anyone else. GaylenePelican Waters, QLD, Home Renovation
I would highly recommend Sunbuilt Constructions. Not only was the quotation lower than other builders but the finished standard was excellent. Marcel and his team handled a difficult project with ease. Great care was taken throughout and the worksite was pristine clean after completion. All details were explained prior to execution. Sunbuilt will have all my future work. JackTwin Waters, QLD, Renovation
I would highly recommend Sunbuilt Constructions to others. The management of the client relationship is exceptional. The quality of the work done is excellent. The ability to 'see' the end result I wanted and add real value with advice about integrating all elements of the project was outstanding. JaneAlexandra Beach Resort, Apartment Renovation
Jennifer and Blair
Marcel and his team at Sunbuilt Constructions have just completed a renovation at our home on the Sunshine Coast. We couldn’t be happier with the workmanship we received with the quality surpassing all of our expectations. Marcel is honest, professional and sincere and he makes a point of keeping his client well informed as to what is happening throughout the project. The transparent payment and management system that he uses ensures that the client knows exactly how much the project is costing and that they can feel confident that any cost savings sourced by Sunbuilt are passed back to them in full. Sunbuilt will be the only contender for our next building project. Jennifer Wilson and Blair Mangan Jennifer and BlairRosemount, Renovation
We cannot recommend Marcel and his team highly enough. Our renovation was complex and required thinking outside the square on a few occasions but nothing phased Marcel and he often went out of his way to help with money and time saving solutions. He even made sure the house was liveable before the reno was finished so we could 'camp' there over Christmas when we were kicked out of our holiday rental for 2 weeks. The C2CPRO system was a game changer and even though I had never renovated before, I had the confidence to make informed decisions about our budget and knew exactly where our money was going - with the assurance that there were no hidden mark-ups in the bills we paid. LeonaPelican Waters, QLD, Full Home Renovation
Sunbuilt Constructions have assisted me with two renovations to date over three years. The latter quite a significant one which included a complete internal and external makeover, large workshop, bathroom, kitchen, games room, garage, pool and outdoor entertainment area with flyover roof. I highly recommend the skills and ideas that this company brings to the table. The expertise is second to none whilst remaining consistent to bring your own ideas to fruition. I tabled my budgets through the renovation and in Sunbuilt worked with me to progress through stages of the build. I have more to do to complete my home and already in discussions with Sunbuilt to finalise the build to the high standards I have become accustomed to. LukeSunshine Coast, Renovation
Tina and Lise
We had an old asbestos veranda that was about to fall down, Sunbuilt Constructions helped to secure it before we even choose them for the demolition and rebuild. This helpfulness and practical attention to our needs remained throughout the process. They turned up in time, accepted our changes and helped with good ideas for the specific needs we had. Very professional, reasonable cost, tidy even our neighbours were happy. Would recommend these guys anytime. Tina and Lise Nambour, Deck
Worked with Sunbuilt Constructions as a subcontractor, I can honestly say that the amount of time and the attention to detail that the builder put in was the highest quality. Additionally, the builder was consistently looking to save the clients money and achieve exactly what they wanted in regards to change. Overall I would highly recommend Sunbuilt Constructions. ZacCaloundra, Subcontractor
