Real Stories From Homeowners Who Built With Cobalt

Google Review
The team at Cobalt Constructions recently finished building our family home. After our original builder went into liquidation forcing a delay we found Cobalt and approached them to see if they could build our home. We have been very impressed with the high quality of the build as it was evident from the start that Jarrod and his team pride themselves on their work, ensuring everything was completed to high standards. The team at cobalt were wonderful to communicate with throughout the entire process and were honest and open communicators. We loved getting to know them all and would highly recommend the company for a great custom build! Thanks again for creating our wonderful home.

Jarrod, Katherine and the Cobalt team were brilliant to work with and have delivered our dream home. Their care and attention to detail shines through in the incredible quality of the finished product. We couldn’t be happier. From the initial consult the team was friendly and enthusiastic. They presented multiple options every step of the way and were always open to chatting through our thoughts and feelings to ensure we made a decision that met all our needs. Jarrod’s creativity, passion for problem solving, and love of efficiency took our design to the next level. We were particularly impressed with how communicative the team were, especially after hearing nightmare stories about builders ghosting their clients or being unreachable. Katherine and Jarrod were always available and we never waited more than half a day to hear back after emailing or leaving a voice message. By the end of the project we felt like we had gained trusted partners, not just builders. Now that we’re in the house we miss them!
