Are you looking for home construction and renovation costs in Sydney? At Matrix Estimating, we provide fast, accurate, and detailed cost estimates for your home construction and renovation projects in Sydney. Using an independent Quantity Surveyor puts you in control of your build from the very start. Your home is fully measured and priced exactly as a builder would do it — every wall, window, door, finish and fitting is accounted for upfront. You receive a detailed Bill of Quantities (BOQ) and a clear cost spreadsheet that removes guesswork, prevents missing items, and locks down your true build cost early. By issuing the same BOQ to multiple builders, you get genuine apples-with-apples pricing, fewer variations, and far less risk of budget blowouts — giving you clarity, confidence, and control throughout the entire build.


Embarking on a self-build project is an exciting adventure, but navigating the costs can be overwhelming. At Matrix Estimating, we’re here to guide you through the process with expert advice and accurate cost breakdowns, putting you in control and allowing you to move forward with confidence.

Cormac was indeed very helpful - providing a detailed construction price range so we knew where to begin by way of commencing our budgeting process. Not many QSs provide such goodwill. Highly recommended

I recently engaged Cormac to assist with estimating a large residential construction project and was genuinely impressed. His work was thorough and detailed — every line item was considered, nothing was glossed over, and the output gave me real confidence going into the quoting stage. He was also generous with his time, happy to walk through his methodology and answer questions without rushing. That kind of transparency is rare and genuinely useful when you're trying to understand the numbers, not just receive them. I'd recommend Cormac without hesitation to anyone needing accurate, professional estimating on significant volumes of construction work.

Cormac from Matrix Estimating has delivered a high-level estimate that demonstrates both depth and breadth of understanding. While preliminary in nature, the estimate appears to comprehensively cover the full scope of works, giving us a strong foundation for early-stage planning and decision-making. Cormac’s extensive construction knowledge is clearly evident in the way he approaches costings—his ability to translate technical detail into practical, well-structured estimates is a real asset. The breakdowns are clear and logical, with a level of detail that instils confidence in the numbers, even at this early stage. Communication has been seamless throughout. Cormac is responsive, approachable, and easy to engage with via one-on-one Teams meetings. He takes the time to explain his rationale and is open to feedback, which makes the process collaborative and efficient. Upon completion of the project, I am looking forward to comparing actuals V estimate. Highly recommended for anyone seeking a knowledgeable, professional, and easy-to-work-with estimator who brings clarity and confidence to the early stages of a project.

I was very pleased with the estimate that Cormac Gray put together for our new build. This will allow me to have confidence in knowing what the final cost of the new house will be and hence arrange finance. Cheers Barry Gilbertson

We highly recommend Matrix Estimating for anyone needing clarity and confidence around building costs. We engaged Matrix Estimating after receiving a builder’s proposal that lacked a clear cost breakdown, leaving us feeling overwhelmed and unable to make a confident decision about proceeding with our build. Cormac completely changed that by delivering a new, detailed, and categorised estimate that brought structure and transparency to the project. He took the time to walk us through the cost breakdown and clearly explained the underlying methodology, including the assumptions and benchmarks used. This enabled us to make informed budget decisions with a solid understanding of where each cost originated. From the outset, Cormac was professional, responsive, and delivered exactly what we needed. His report met our brief perfectly - easy to interpret, methodically structured, and underpinned by industry-standard metrics and evidence-based logic. Thanks to Matrix Estimating, we’re now in a much stronger position to engage with our builder on a definitive, realistic budget. Cormac listened, supported us through the process, and delivered a service that reflects both technical expertise and practical insight.

We’ll get back to you within 1 business day with next steps and pricing.
