Hi, I’m Hai Nguyen, founder of Newin Building Estimating Services, and that’s what I’ll help you do!

As leading industry experts, Newin’s established service assists developers across Sydney and Melbourne who may not have the skills, time, or resources to accurately cost projects.

Over the years, Newin has become a preferred and trusted partner choice for developers. We specialise in development projects ranging from $1 million up to $150 million, including residential, commercial, and industrial projects.

The Newin team is experienced at working with developers throughout all stages of a project to provide peace of mind and security that the development will continue through to completion.

Our accurate and thorough reports of on-site feasibility and design costings will eliminate the risk of underestimating the cost of construction and ensure you and your clients are in the best position to maximize profits on all developments.

“I found using Newin Estimating Services helped me win more business. Their professional approach and efficiency enabled me to go for more tenders and increase my strike rate. I would recommend their services to any builder or subcontractor who does not have the time to do estimating themselves”
