What Our Clients Say
Real feedback from homeowners across the Illawarra
"We recently had two new decks completed by this company and couldn’t be happier with the result. One was a brand new covered deck, and the other involved transforming an old tiled deck into a much larger timber deck — more than doubling the size and completely changing the space for the better."
"I found Brad to be very professional when I had any questions he would always get back to me quickly they built my extension and its magic im very happy with the end result. Also all the staff were very polite and hard working and clear up all the rubbish."
"Fantastic experience from start to finish. The team was professional, reliable, and delivered high-quality workmanship. Communication was excellent throughout the project, and the finished result exceeded our expectations. Highly recommend Brad and his team to anyone looking for quality work and great service."

Local Builders Who Deliver on Every Promise
At the heart of Integrate Building are three directors who share more than just a passion for construction, they share a lifetime connection to the Illawarra region. Having grown up in this beautiful coastal area, we understand the unique character of local homes, the specific challenges of building in our climate, and most importantly, the values that matter to Illawarra families. This deep local knowledge isn't just about knowing the best suppliers or trades. It's about genuinely caring for the community that shaped us.
When we say "we care and are committed," it comes from a place of genuine connection. We're not just building houses, we're enhancing the neighbourhoods where we grew up, where our families live, and where we plan to stay.
