Dear Home Owner or Owner- Builder,

Want to know how much it’ll cost to build?
Don’t want to risk getting “caught out” with an overpriced builder?

Are you planning a new home build or construction and need quantity surveying or expert project management support?

Hi, I’m Hai Nguyen, founder of Newin Building Estimating Services, and that’s what I’ll help you do – cost and manage your building projects to ultimately ensure your project gets completed to budget and without any cost surprises.

We are a Sydney and Melbourne based property and construction advisory firm specialising in Construction Cost Estimate Reports, Quantity Surveying, Project Management and Cost Management services. We work with home-owners and owner-builders at various phases: prior to construction, during construction, and post-construction.

Our why?

Over the years we’ve seen clients get caught out with overpriced builders, poor project tracking systems, inaccurate costings, or simply “paying too much”, sadly leaving many financially strained.

We have a proven risk management system and industry track record for addressing all these.

Our Quantity Surveying Services

Construction Cost Management and Contract Administration

Construction Cost Project Claim Assessments and Performance

We’ll assess and recommend progress claims and variation claims. We’ll monitor project budgets,  the costs of works complete to date, cost of works in progress and/or cost of defective works (if necessary), ultimately ensuring the cost of construction is within the approved budget.

With our construction project management services, we offer on-site assessments of the builders progress claims.

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.
