Top 5 Home Renovation Mistakes (And How to Avoid Them)

Renovating your home can be an exciting way to increase functionality, improve comfort, and boost property value — but if you're not careful, it can quickly become stressful and expensive. Whether you’re planning a home renovation in Sydney or Perth, these five common mistakes could derail your project.

1. Underestimating the Renovation Cost

Many homeowners set unrealistic budgets based on TV shows or assumptions. In Sydney and Perth, renovation costs often range from $2,000 to $4,000+ per square metre depending on the scope and finish quality. Forgetting to include costs like demolition, permits, contingency funds, or structural work can lead to serious budget blowouts.

Tip: Get a clear quote from a licensed renovation builder who can break down costs and flag potential issues early. At Sky Building Construction, we provide transparent estimates tailored to your home’s condition and goals.

2. Choosing the Cheapest Builder

While it's tempting to go with the lowest quote, this often leads to poor workmanship, delays, or even legal headaches. A qualified, experienced builder will factor in necessary details that prevent costly rework later.

Tip: Always check licensing, reviews, and past projects. Ask how the builder communicates throughout the job.

3. Ignoring Council Regulations or Permits

Homeowners are sometimes unaware that even simple home extensions in Sydney or Perth may require approval. Non-compliance can lead to fines or force you to undo the work.

Tip: A professional builder will guide you through council approvals and ensure your renovation complies with local building codes.

4. Rushing the Design Phase

A poor layout can ruin even the most beautiful renovation. Whether it’s lack of natural light, awkward room flow, or insufficient storage, design mistakes are hard and expensive to fix once construction starts.

Tip: Spend time planning your floorplan and functionality — and work with a team who understands lifestyle-focused design.

5. Failing to Plan for the Unexpected

Older homes often reveal surprises — hidden damage, outdated wiring, asbestos, or plumbing issues. Without a buffer in your budget or schedule, these setbacks can delay your project.

Tip: Build in a 10–15% contingency and expect a few hiccups. The right builder will help you navigate them smoothly.
