Finding the right builder matters more than most people realise. Not only is it about price, design, and structural integrity, it’s about working with someone you can trust. Someone who’s upfront, easy to communicate with, and has a proven track record of delivering high-quality homes without cutting corners or disappearing halfway through the job.
We’ve all heard the horror stories. Delayed builds, unexpected costs, builders going under, and homeowners left in the dark. That’s why asking the right questions early on is so important. It helps you get a clearer picture of who you’re working with, how they operate, and whether they’re the right fit for your project.
To help you make a more informed decision, we’ve rounded up ten of the most important questions to ask a builder when building a new home. These are the kinds of conversations that can potentially save you a lot of time, money, and stress.
Key takeaways
One of the most essential questions to ask before you sign on the dotted line is whether your provider is a licensed builder and fully accredited to operate in your state. A registered builder will meet all industry standards, hold required insurances (like home warranty insurance)
They will ultimately be accountable for delivering your dream home safely and legally.
Choosing a reputable builder with the proper licensing is your assurance that you’re working with a professional who’s invested in quality, safety, and transparency throughout your home-building journey.
Timeframes matter, especially when you’re first planning and budgeting for your new home. Ask your modular builder how long it will take to receive a detailed, itemised quote, including allowances for site works, materials, and potential upgrades.
While the actual cost of your build may change depending on inclusions you choose, any design modifications, and site conditions, the earlier you get a quote, the better positioned you are to determine if this is the right builder for you.
Next, get a clear understanding of the contracted build time. While many builders offer indicative timelines, the best builders will give you a realistic schedule and explain how they manage unforeseen issues, handling delays, and seasonal interruptions such as holidays.
Ask if you’ll have regular meetings with your site manager to review progress and stay updated. This transparency adds accountability and gives you added peace of mind, especially if your build takes longer than expected.
Not all fixtures and appliances are created equal. Ask whether they use premium appliances and trusted brands for lighting, tapware, flooring, and cabinetry.
Using reputable brands not only contributes to quality and reliability but also affects maintenance, warranties, and resale value. This is particularly important when comparing standard inclusions and potential upgrades on offer, as the difference between low-end and high-end fittings can be of real significance over time.
Some builders specialise in flat, uncomplicated blocks, but that doesn’t help much if you’ve found the right block in a trickier location. Whether or not you’re dealing with a sloped site, tight access, or reactive soils, it’s worth asking early about your builder’s approach to complex sites and any additional engineering or excavation that may be required.
These details can affect design, orientation, costs, timelines, and ultimately, whether you can build the home you’ve envisioned. A skilled provider will guide you in the right direction, even when the terrain isn’t ideal.
Modular construction allows for efficiencies, but that doesn’t mean it should be rigid. One of the smartest questions to ask a builder when building a new home is how they handle mid-project changes. For example, if you want to change fittings or fixtures, it’s best that you know what's possible and at what cost.
Ask if they have an online portal where you can manage change requests, and whether they offer direct access to decision-makers throughout the build.
Most modular builders offer a series of base designs, but the best ones know that clients often like to add their own unique touches. Ask whether you can modify your standard plan, and what limitations (if any) exist structurally or within the building contract.
Some changes may be included, while others may affect pricing or timelines. Understanding this early helps avoid unexpected costs and ensures your building experience is tailored to what you have in mind.
A high-quality and in-depth design consultation can make a big difference to your entire building process. It’s your opportunity to explore layout options, review comprehensive inclusion lists, select materials and colours, and fine-tune orientation for climate and energy flow.
Ask them to outline what’s included in the consultation: will you get 3D walkthroughs, site assessments, or energy efficiency modelling? A builder who invests time in this stage is setting you up for success in every phase of the construction process.
Energy efficiency has a direct impact on comfort, running costs, and resale appeal. Whether you’re chasing a 7-star rating or higher, the right question to ask your builder is how they optimise the thermal performance of their designs.
Consider insulation, glazing, orientation, materials, and ventilation. Ask about their familiarity with standards like NatHERS or BASIX (for NSW).
Ask how they integrate sustainable choices throughout the home-building journey.
It’s important to understand what’s covered once construction wraps up. Ask for a breakdown of the warranties provided, including coverage for minor defects and structural elements, and make sure this is clearly outlined in the building contract.
You’ll also want to know how the home has been engineered for long-term performance. Many modular builders specify a 50-year design life and construct to meet the National Construction Code. It speaks to both quality control and durability across the full building process. Getting this right can offer added peace of mind well beyond the build itself.
