For architects & building designers
Construction Cost Estimating for Architects
Keep Your Design Aligned With the Client’s Budget
Matrix Estimating provides independent construction cost estimating services for architects and building designers throughout Australia. We prepare detailed cost plans, quantity take-offs and Bills of Quantities to help you understand the likely construction cost before the project progresses too far.
Rather than relying solely on broad square-metre rates, we measure the project directly from the drawings and apply current market pricing. This provides a clearer cost benchmark for design decisions, client discussions and value engineering.

Not many QSs provide such goodwill. Highly recommendedPosted on GoogleRoger White3 June 2026Cormac and team did a very thorough job on a tight timeframe. Very happy with the work.Posted on GoogleTobin delaney23 May 2026I 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.Posted on GoogleImogen Scuteri14 April 2026Cormac’s advice stood out to me for being clear, honest, and refreshingly transparent, exactly what I was looking for as a person in need of his excellent building knowledge.

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.

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 GilbertsonPosted on GoogleSera Anticevic30 June 2025We 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.
