What Our Clients Are Saying
Jessie and the Altered Building team were the perfect choice. His communication and quality of work were outstanding, and the whole team was incredibly helpful, flexible, and friendly.

We’ll definitely be using them again!
Evan, Mayfield
We couldn’t be happier with the incredible outdoor oasis that Jesse and team have created for our family. From start to finish, the team was professional, reliable, and an absolute pleasure to work with. They took our vision and brought it to life with thoughtful design, top quality workmanship, and attention to every detail. We highly recommend Altered Building and Renovations to anyone looking for high quality construction with genuine care for their clients.
Leonnie, Maitland
Happy to recommend Jesse and the team from Altered. They did a brilliant job at our house this year building a pool deck in a tricky yard (sloped & lots of council conditions) plus fencing, retaining walls and remodeling our pergola. The whole team were always professional, punctual & reliable. Leaving everything neat and tidy and being respectful of the rest of our property and our neighbours. They made the experience stress-free and we will definitely be using them again for our next few projects. Happy to recommend to anyone.
