Walking into your first consultation for a knock-down rebuild (KDRB) can feel a bit like a first date. You’re nervous, you’re trying to look your best, and you’re desperately trying to figure out if this person is "The One", or if they’re just going to break your heart (and your bank account) six months down the track.

The inspiration for this post actually came from a great thread in the "Building New Homes in Sydney and NSW" Facebook group. A member posted about their first-ever builder meeting and asked: "What questions should I be asking? Is there anything specific?"

The community jumped in with some absolute gold, and Paul from Compare New Home Builders wanted to add a few practical tips too. Because let’s be honest: the right questions today can save you $50,000 and a whole lot of grey hairs tomorrow. Here is your quick-tip reference guide to navigating that first consultation like a pro.

1. The "Vibe Check": Style and Compatibility

As a community member named David rightly pointed out, don’t make the first meeting all about the bottom dollar. If you don't like their style or their way of working, the price won't matter. You are essentially entering into a 12-to-18-month relationship with these people. If the communication feels "off" or they seem defensive when you ask basic questions, it’s a red flag.

When you're trying to how to compare home builders in Australia, you need to look at more than just the floor plans.

• "What type of building work do you specialise in?" You want a builder who lives and breathes KDRB, not just someone who does volume builds in new estates. A knock-down rebuild in an established Sydney suburb comes with unique challenges like narrow access, heritage overlays, and grumpy neighbours.
• "Which projects are you most proud of and why?" This tells you what they value: is it the architectural finish, the speed of the build, or the way they solved a tricky site issue?
• "How many homes do you build a year?" You’re looking for the "Goldilocks" zone. Too many, and you’re just a number; too few, and they might lack the buying power with suppliers.
• "Where can I see your work?" Ask for 3-4 recently completed jobs that you can drive by. Seeing a house that’s been lived in for a year tells a much better story than a pristine display home.

2. The Money Talk: Beyond the "Base Price"

This is where most people get tripped up. The price you see on a glossy brochure is rarely the price you pay when you move in. In fact, understanding why builder quotes can differ by $200,000 is the first step to becoming a savvy home builder.

• "What does the 'Base Price' actually include?" Most builders start with a base price, but you need to know about the "hidden" essentials. Ask specifically about:
  • Site Costs: Excavation, piering, and any necessary retaining walls.
  • BASIX: NSW energy efficiency requirements can add thousands depending on your design and orientation.
  • Services & Connections: Getting electricity, water, and gas from the street to your new home.
  • Stormwater & Export: Getting rid of the "spoil" (excess dirt) from your site can be surprisingly expensive in Sydney.
• "What are your Fixed vs. Provisional Sums?" A provisional sum is basically an estimate for things like site works or cabinetry. If the actual cost is higher, you pay the difference. Ask: "How can we get as many of these provisional prices fixed before I sign?" For a deeper dive, check out our guide on fixed price vs provisional sum building contracts.
• "Who handles the demolition?" Some builders include it; others expect you to clear the site first. This is a massive logistical step in a KDRB project that requires its own set of permits and safety measures.

3. Flexibility and the "Big Ticket" Items

You don’t want to find out three months into the build that you can’t have the kitchen tap you’ve been eyeing on Pinterest because it’s "not on the list."

• "Can I include my big-ticket upgrades at the tender stage?" Paul from Compare New Home Builders always recommends getting your "must-haves" into the tender early. Whether it’s high-end appliances or a specific house facade, get it in writing now so it’s factored into the budget. Knowing what should be included in a builder tender is key here.
• "How flexible are your plans?" Can you move a wall? Can you flip the back of the house to catch the sun? Some volume builders are strictly "as is," while custom or semi-custom builders will work with you.
• "Can I choose my own suppliers for specific items?" Some builders have "locked-in" ranges. You need to know if you’re restricted to their choice of tiles and carpet or if you have the freedom to shop around for that specific Italian marble you love.

4. The Process: Tenders, Contracts, and Risk

The paperwork is where the real "build" begins. Understanding the timeline and the risks is crucial for your peace of mind. It's important to understand the hierarchy of paperwork; we've broken down the builder quote vs tender vs estimate explained in a separate post to help you avoid common traps.

• "Tell me about your tender and contract process." Be wary of "early contracts." Signing a contract before all the site testing and planning is done often leads to a mountain of "variations" later on. Variations are where the budget goes to die.
• "What happens if I don’t sign the final contract?" Life happens. If you pay for a tender or a site start but decide not to proceed, how much of your deposit is refundable?
• "What is the expected timeline for approvals and construction?" Sydney councils aren't exactly known for their speed. Ask the builder for a realistic estimate of the pre-construction phase versus the actual build time.
• "Do you use your own team or independent trades?" This affects consistency. Knowing the builder has a regular crew of trades who know their standards, rather than just hiring the cheapest person available that week, is a huge plus.

5. The "What’s NOT Included" Checklist

It sounds strange, but you need to ask about what they don’t do. These are the items that can catch you off guard in the final weeks when your bank account is already feeling the pinch.

• Driveways and Paths: Is this included or is it a post-handover job for you? Believe it or not, many "turnkey" packages still leave the driveway to you.
• Landscaping and Fencing: Most builders exclude this, but you need to budget for it. In a KDRB, your old fences might be trashed during construction, who pays for the new ones?
• Solar and Smart Home Tech: If you want a sustainable home, check if they handle the solar installation and home automation, or if you need to bring in your own specialists.
• Council Contributions: These "Section 7.11" or "7.12" contributions can be thousands of dollars paid directly to the council. Ask if the builder manages this or if it’s on you.

Why These Questions Matter

In the Facebook group, one contributor made a great point: prices can fluctuate due to global issues like oil prices or supply chain shifts. Asking about price fixing and how the builder handles market volatility is a very smart move in 2026.

As Paul often says, "A good builder will welcome these questions. They want an educated client because it means fewer surprises for everyone."

At the end of the day, a first consultation shouldn't feel like an interrogation, but it should feel like a deep dive. You are trusting someone with your single biggest investment. If a builder gets defensive or vague when you ask about site costs or drive-by references, that’s a massive red flag. Use these questions to weed out the "cowboys" and find a partner who is as committed to your dream home as you are.

FAQ: Navigating Your First Builder Consultation

How long should a first consultation take?

Usually between 45 and 90 minutes. It should give you enough time to go through your vision and ask the essential questions mentioned above without feeling rushed.

Should I bring my own plans to the first meeting?

If you have them, yes! Even if they are just sketches or Pinterest boards. It helps the builder understand your style and whether their current floor plans can be adapted to suit you.

What is the difference between an estimate and a tender?

An estimate is a "ballpark" figure based on general costs. A tender is a much more detailed document based on actual site tests, surveys, and your specific selections. Always rely on the tender for your final budget.

Why are site costs so high in Sydney?

Sydney's geography is tricky. Between reactive clay soils, hidden rock (especially in the North and East), and sloping blocks, the "groundwork" often costs more than the actual flooring and walls.

Is it okay to ask for a discount at the first meeting?

You can, but it’s often better to ask for "added value" (like an upgraded appliance package) rather than a straight cash discount. High-quality builders know their worth and have fixed margins to ensure they stay in business to finish your home!
