Budgeting for Your Dream Home

One of the biggest questions people have when planning a new build, renovation, or extension is simple: What will it cost — and how do we keep it on track?
With the right planning, clear communication, and a builder who understands your priorities, your budget can stay predictable from start to finish.

Here’s how to set realistic expectations and avoid costly surprises.

1. Understand the Key Cost Factors

Every project is different, and several elements influence the overall cost:

• Scope of work — A full renovation or extension has a different structure to a brand-new build.

• Materials & finishes — High-end tapware, custom cabinetry, timber joinery, and heritage restoration all influence pricing.

• Structural changes — Removing walls, raising a Queenslander, adding a second storey, or upgrading foundations and services will increase cost.

• Approvals & compliance — Heritage overlays, council requirements, private certifiers, and engineering all play a role.

Understanding these factors early helps set a realistic and comfortable budget from day one.

2. Plan for a Contingency Fund

Even with excellent planning, older homes — especially Queenslanders and character cottages — can reveal hidden issues once work begins.

It’s wise to allow 10–20% contingency for items like:

• Hidden structural damage

• Asbestos removal

• Replacing unsafe wiring or plumbing

• Bringing old framing or footings up to current standards

For new builds, a contingency gives breathing room for small design tweaks or unexpected supplier delays.

3. Get a Detailed, Fixed-Price Contract

A clear, fixed-price contract is your best protection against budget blowouts.

It should outline:

• Labour and material costs

• Inclusions and exclusions

• Prime Cost items and allowances

• Timelines and payment stages

• Any potential additional costs

The clearer your documentation, the fewer surprises later on.

4. Align Your Design with Your Budget

One of the most common budget challenges happens long before construction even begins:
falling in love with a design that doesn’t match the budget.

Working with a Design + Construct builder solves this problem.

We guide you through how design decisions affect cost — before plans are final.
This leads to:

• fewer variations

• smarter selections

• a smoother, more predictable build

5. Prioritise Must-Haves vs. Nice-to-Haves

When budgets tighten, focus on the areas that create the most long-term value:

• Structural improvements

• Kitchens and bathrooms

• Durable flooring

• Energy efficiency upgrades

Finishes like decorative lighting, landscaping, and styling pieces can always be added later with minimal disruption.
