House extension under construction with new timber frame

Most extensions start with a site visit and a rough budget. We measure up, check what your block allows, and give you a written ballpark within a week. Once you’re happy, we bring in the designer and engineer and turn it into a fixed-price contract.

What’s included

  • Plans, engineering and council or CDC approval handled for you
  • Fixed-price contract with a written schedule of works
  • Home Building Compensation Fund cover on eligible jobs
  • One site supervisor and a weekly progress update

FAQ

Extensions & new builds: questions

Do you handle council approval?

Yes. We coordinate the designer, engineer and certifier, and lodge a CDC or DA depending on what your block allows.

Can we live at home during the build?

Usually, yes. We section off the work area and agree on access, noise hours and bathroom use before we start.

How do payments work?

Progress payments at agreed stages written into the contract. A deposit is capped by NSW law and is only taken once insurance is in place.
