Home EXTENSION FAQs

Yes, most home extensions require council approval, or Complying Development Certificate, particularly if you’re adding height or making significant structural changes. At HMS Projects, we assist with the entire planning and approval process, ensuring that your extension complies with local regulations and meets all necessary requirements.

A Development Application (DA) is a formal request submitted to your local Council, seeking approval to carry out a building project.

Alternatively, a Complying Development Certificate (CDC) offers a streamlined process for projects that meet specific criteria. It combines both planning and construction approval in one application, making it a faster option for certain developments. CDCs can be assessed by either the Council or an accredited certifier, provided all relevant standards are met and the construction adheres to the Building Code of Australia. While CDCs often have a quicker approval process than a DA, they are only applicable to specific types of development.

Each Council has its own set of requirements for both DA and CDC approvals, however HMS Projects will be able to guide you in the direction of the best option for your extension.

The timeline for your extension will depend on the size and scope of the project. While small extensions might take a few months, larger and more complex builds can extend to six months or longer. We provide clear timelines during the planning phase and keep you updated throughout the project to ensure everything stays on track.

Absolutely. Our goal is to create extensions that blend seamlessly with your home’s current design and aesthetic. We carefully select materials, finishes, and architectural features that ensure a cohesive and harmonious result.
