So, You Have Your Concept Plans – What’s Next?

Congratulations! You’ve reached an exciting milestone in your custom home journey—the concept plans are in your hands. These plans lay the foundation for the home of your dreams, but what comes next? To move forward with your fixed-price quote, your builder needs you to make a range of decisions and selections. Providing these details early is crucial. Without them, your builder may need to include a provisional sum in the quote—a placeholder estimate for items or services that haven't been fully specified yet. The downside of provisional sums is that they can lead to cost variations later, as the final price will depend on the actual cost of your selections. By making clear decisions upfront, you’ll ensure your quote is accurate and minimise the risk of budget surprises down the track.

To help guide you through this process, here’s a checklist of decisions and selections you’ll need to consider to keep your build moving forward smoothly.

By finalising these selections as early as possible, you’ll avoid the pitfalls of provisional sums and ensure that your builder can give you a reliable, fixed-price quote.
