Frequently Asked Questions
How long does a home extension or addition take?
The timeline depends on the size and complexity of the project. Smaller extensions may take a few months, while larger second-storey additions can take longer. We provide a clear project timeline during the planning stage to ensure you know what to expect.
Do I need council approval for my extension?
Most home extensions require council approval or a Complying Development Certificate (CDC). We handle all necessary permits and approvals to ensure your project complies with local regulations.
Can I live in my home during the construction?
In most cases, yes. We aim to minimise disruption to your daily life, but for major renovations or second-storey additions, temporary relocation may be recommended for safety and convenience.
Will my extension blend seamlessly with my existing home?
Yes. We design and build extensions to match your home’s existing structure, materials, and finishes, ensuring a cohesive and natural look.
