Ollie came to ours to fix an exterior wall that had some holes in it after a structure had been removed. The entire process from enquiring to completion was slick and efficient. The work looks great, Ollie was quick to reply and easy to talk to throughout. It's difficult to find a reliable builder these days but it's safe to say I'd happily put my confidence in Ollie again for anything I need doing in the future.

Thanks to Ollie for coming out this evening to quote for our double storey extension. Up front and honest about the size of the job, concerns we might have and ultimately how much it could cost.

Excellent service. These guys came to my place to fix up some brickwork. They assessed the problem, told me how it'd be fixed and gave me a great quote. We then arranged a time and day for the job to be done. They arrived on time, answered my questions and did a great job. No mess left behind etc. Excellence all around. Highly recommended.

Ollie and team at CNR did a great job repairing a failed lintel and associated brickwork on my outhouse in New Brighton. Responded quickly, acted professionally and were very pleasant. I wasn't sure anyone would take on such a small project, but they fitted it in the same week no trouble! I wouldn't hesitate to recommend them.

We recently used CNR Construction for a small job — just pointing a few walls — but from start to finish they treated it like a major project. The team was polite, friendly, and very professional. Even though the scope was small, the quality was outstanding. The pointing is neat and consistent, with smooth joints and clean edges. No sloppy mortar, nothing rushed. They clearly take pride in craftsmanship, no matter how small the job.

Wow! What can I say about Ollie and his team? Fantastic from beginning to end. The work that has been done is better than I could have imagined! We now have the most beautiful open space and the work is beyond perfect. So professional, always checking we were happy, always communicating, and everything was so organised. Already asked Ollie if he can do our garden next year as we are so impressed!
