Our History

Everything at Black Diamond Projects started with our esteemed director, Toby Ziedan.

Toby comes from a lineage deeply rooted in the building and development industry, making construction more than just a profession—it's a family legacy. His early exposure to the world of building, thanks to his father, a highly successful Gold Coast Developer, ignited Toby's passion for construction at a young age.

With a clear vision for innovation, sustainability, and exemplary customer service, Toby founded Black Diamond Projects. Under his leadership, the company strives to set industry standards, delivering exceptional quality while prioritizing customer satisfaction.

Had Toby and the crew do an amazing shop fit out on really short notice. Not only did they complete works by the specified deadline but also to immaculate standard.I worked closely with Toby and Jake over a week and cannot speak highly enough of them these gents have an old school work ethic and really put in the hard hard yards to produce results.Would gladly would work with them again.

These guys are just amazing. Prompt, efficient and tidy. I needed a job done urgently and Toby and the team took time out on a Sunday to rectify. Thank you guys.

We live interstate and needed to have our Surfers Paradise apartment renovated - including a new bathroom. We are delighted with the quality of the job and the process. Toby was fantastic to work with! He was always available on the phone to chat and gave us regular updates. Nothing seemed to be too much trouble for him, and he was very obliging and professional. His team of tradies were good & decent guys who were respectful and great to work with. We are very happy with the end result and the whole process was trouble free. Any curve balls thrown at us by the apartment were quickly & painlessly resolved by Toby & the team. I would definitely use Black Diamond Projects again - and would have absolutely no hesitation in recommending them to others. They were polite, fussy with their workmanship, professional and VERY reasonably priced. We were very happy with our experience with them.

I can’t say enough about the bathroom that Toby and his crew from Black Diamond have created for us. The results speak for themselves. All the way through their number 1 priority has been our satisfaction. They were all very easy to work with. Their work ethics were absolutely top notch. They were the cleanest group of tradesmen I’ve ever dealt with. They were constantly cleaning up after themselves. We believe that we got more than we asked for. Thank you again to Toby, Tim and everyone else who worked on the job.

Black Diamond carried out a full reno on my 3-bedroom unit in Broadbeach which included a full wall repair, new kitchen, upgrade of the bathroom, new front door, new lighting and fan replacement,Toby was involved from the start and I developed a very close working relationship with him and his team. A few minor jobs required after completion were quickly attended to.Very happy with the result (as are the new tenants) and will use Black Diamond again.Apart from the good quality work I found Toby's interpersonal skills really helpful in ensuring what i wanted was done. Toby also had plenty of interior design ideas which i found most useful. As I am located overseas this greatly assisted in getting the job done on time and to my satisfaction. We regularly chatted by WhatsApp and Toby always made himself available to chat.Glad to provide this recommendation
