How We work

We follow a meticulous process to ensure that every project is completed to the highest standard.



We collaborate with you to understand your vision and requirements, creating a concept that aligns with your goals, timeline and budget.



Our team works with your architect (or we will engage our own) to develop a detailed plan bringing your concept to life.



We transform the design into reality, carefully implementing each detail to ensure a high-quality, functional, and visually appealing result for your project.


We’ve been really impressed with the care and respect of our home during the demolition. Cameron’s attention to detail and his ability to listen and meet our exact expectations is something we noticed and value straight away. We’re already scrambling to book in the next phases of our renovation with Cameron and his team. Highly recommend Diamond Building & Construction.


    100% recommend Diamond Building and Construction. Just had my bathroom completely renovated. The entire process was top notch. Cameron and his team were completely professional, their eye for detail and communication was great. Such an easy and quick process. Left with an amazing bathroom and could not be any more happy!

      I contacted Pat as he was highly recommended, he and the boys were awesome. We had some unforeseen issues pop up due to renovating an older house, but Pat took care of everything and put us at ease through the stressful process. The boys were friendly, honest and on time. Pat is extremely thorough and very particular with the work quality so you’re in good hands. We can’t thank them enough for all the work they did in transforming our home.
