Common Renovation Mistakes to Avoid (and How to Get It Right)

Renovating your home is exciting — but without the right planning, it can quickly turn into a costly and stressful experience. Over the years, I’ve seen the same renovation mistakes happen time and again, often leaving homeowners disappointed with the result.

If you’re planning a renovation, here are the most common mistakes to avoid — and what to do instead — so you can create a home you truly love.

1. Skipping the Planning Stage

The mistake: Jumping straight into the build without a clear plan.
Why it’s a problem: Without a detailed design, budget and timeline, you risk making rushed decisions, costly changes mid-project, and ending up with a space that doesn’t work for your lifestyle.
The fix: Invest in a professional design phase. This should include a floor plan review, finishes schedule, 3D visuals, and a clear scope of works before construction starts.

2. Underestimating the Budget

The mistake: Setting an unrealistic budget or forgetting to include contingency funds.
Why it’s a problem: Renovations often uncover surprises (think hidden water damage or outdated wiring) that can add to your costs.
The fix: Always allow a contingency of at least 10–15% for unexpected expenses. Work with your designer to ensure selections fit your budget while still achieving your desired look and quality.

3. Focusing Only on Looks

The mistake: Choosing finishes and layouts based purely on aesthetics.
Why it’s a problem: A beautiful space that’s impractical will quickly frustrate you. Poor layout, lack of storage, and insufficient lighting can make even the most stunning renovation feel like a disappointment.
The fix: Balance beauty with function. Consider how you use your home daily, traffic flow, and practical elements like storage, lighting, and durability.

4. Choosing the Wrong Trades

The mistake: Hiring based solely on the cheapest quote.
Why it’s a problem: Poor workmanship can lead to costly repairs down the track — not to mention unnecessary stress.
The fix: Choose licensed, insured, and highly reviewed trades who understand your project vision. A designer can connect you with trusted builders and trades who deliver both quality and professionalism.

5. Making Decisions on the Fly

The mistake: Selecting finishes or layouts during construction without seeing the bigger picture.
Why it’s a problem: This often leads to mismatched materials, delays, and budget blowouts.
The fix: Finalise all your selections before work begins. A finishes schedule ensures everything is coordinated and ready when needed, keeping the project smooth and cohesive.

6. Ignoring Resale Value

The mistake: Personalising the space to your tastes without considering long-term appeal.
Why it’s a problem: If you plan to sell in future, overly unique choices can deter potential buyers.
The fix: Blend timeless design elements with your personal style. A designer can help you add personality without compromising resale value.

7. Not Engaging a Designer Early Enough

The mistake: Bringing in a designer after construction has started.
Why it’s a problem: You miss the opportunity to fix layout issues, avoid costly mistakes, and maximise the potential of your space.
The fix: Engage a designer right at the start. They’ll guide you from concept to completion, ensuring every decision adds value and enhances your lifestyle.

Final Thoughts

A successful renovation is the result of careful planning, the right team, and thoughtful design choices. By avoiding these common mistakes, you’ll save time, money, and stress — and end up with a home you’re truly proud of.
