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

Latest tips from Newin

Find a Local Builder- Factors to Consider
Whether you’re building a new home or renovating an existing one, selecting the right builder is a crucial step in ensuring your project meets your expectations. The process can be daunting, especially if it’s your first time, but by taking a considered approach and avoiding common pitfalls, you can set yourself up for success. To help guide your decision-making process, here are six essential tips to keep in mind when choosing a builder.
Focusing solely on the cost when choosing a builder is tempting, but it’s important to dig deeper than the numbers. The cheapest or most expensive quote doesn’t always mean the best value.

Sydney Home Extension Tips
Whilst it can be easy enough to get carried away with a home extension, you could end up blowing your budget big-time in the process especially when it comes to the more discretionary spending areas like quality of finishes.
Ask yourself – Do I need that $20,000 granite kitchen benchtop or will the $7,000 one still give my kitchen that new edgy look?
Aesthetics are certainly important, but functionality (and budget) should come first.
Minor additions like a new cabinet for extra space or a wider benchtop can enhance the functionality of your space without punching a hole in your pocket.

Home Building Tips Sydney- 6 Ways to Play it Safe
The risks associated with building your own home can be life-changing, and not in a good way. Both Sydney homeowners and builders have responsibilities to ensure the process goes smoothly, but it’s important to know what these are before signing off on a building contract. Here are six ways to manage the risks and play it safe.
The first step in avoiding the risks of home building or completing renovations is to understand what they are. One of the most critical risks involves the health and safety of all the trades and tradies engaged with the project.
Make sure you have a detailed list of all the contracts needed to complete the project, and the key contacts, and know how to organise them all, so everyone turns up at the right time to do what needs to be done.
