"When I first met Rowan, I felt instantly comfortable and was happy to trust my renovation to him, knowing it was in good hands. He has been the consummate professional throughout the whole process, taking all the stress and headaches in his stride, and away from me! He and his team have a great rapport and work really well together which was evident in how smooth and efficiently the transformation of my home was completed. Rowan arrived when he said he would, kept all his promises and I felt included and informed the whole way through. Thank you so much, I love my new home and cannot recommend Rowan and the Coastline Team high enough."
- Jacqui Challen, Boat Harbour Extension

"I approached Coastline for a complete solution with a home extension and in-ground Pool. My home is architecturally designed, very unique and has a ‘Flame Zone’ bush fire rating. Coastline was able to design and build a Home Theatre and Office that not only looks like it was always there but visually enhanced the home. I found Rowan to be very professional and honest though-out the quoting and design process. I liked Rowan’s work ethic and dedication to ensure the finished product simply looked good, Rowan’s advice when it came to spending extra money for a high quality finish or how to save money was also very helpful. I would recommend Coastline for any job, I now have a great Theatre Room, Home Office and Wine Cupboard thanks to Rowan and his team."
- Craig Pearce, Valentine Extension

I would like to thank Rowan and the team from coastline builders and designers after they turned my run down house in mayfield into a work of art. The quality of workmanship and overall finish displayed around the house is second to none. This was an extremely in depth job, taking the house back to the framework inside as well as changing the layout at the same time, and to complicate matters even further I was deployed to another country with the Royal Australian Air Force during the entire renovation. Put simply coastline are extremely professional and flexible and I would trust no one other than Rowan for any building work I need done in the future.
