Do I need to get a
Building Cost Estimate?

We get asked this question all the time and the answer is- can you afford not to? Can you afford…


Uncertainty during construction is an unfortunate reality, especially with building and labour cost increases in the last two years. We aim to empower you by offering greater peace of mind that you’ll be able to complete your project within budget.


Financial loss?

Building costs are going up, with some materials 4X compared to two years ago. We’ll help you identify material and labour cost-saving opportunities in the thousands.

Project delays?

With highly transparent cost plans and documentation that can be communicated to trades and suppliers, your project will have a much higher chance of being completed without costly delay. We can point out areas of your build where potential delays can occur to allow for fore sight in the construction timeline.


Financial exposure?

Incorrect cost plans and building budgets may affect your construction loan and bank finance capacity. We aim to help minimise this risk by providing highly accurate cost reports based on the latest market rates.
