One of the most common questions homeowners ask when considering a renovation is: how long does a home extension take?
While timelines vary depending on the project size and complexity, most home extensions follow a structured process from design to construction.
Understanding the typical timeline helps homeowners plan ahead when exploring home renovation and extension projects in Mornington Peninsula.

Can You Stay in Your Home During an Extension?

Every project is unique, and the timeline will depend on factors such as:
- Design complexity
- Size of the extension
