Thank you to the Coast Building team for working tirelessly to remodel our house into our dream home. From the initial consultation, through all the hoops, to the final lick of paint, the team was friendly, professional and worked hard to complete the project in a timely manner. We couldn’t be happier!
We are absolutely thrilled with our new home, and owe a big thank you to Stuart Colley for the incredibly positive experience in building our new home. Their teams attention to detail, clear communication and commitment to quality resulted in a beautifully, well-crafted home that we couldn’t be more happy with. From the initial design stage to the final handover, the entire process was stress free and very professional. I highly recommend Coast Building & Carpentry to anyone looking for a reliable and professional builder.
As first timers to home building we were pretty daunted by the whole process but Stuart and his team were excellent. Great communication and problem solving, going above and beyond to help get us the best outcome. The quality of the build exceeded all of our expectations.
