FAQs about home extensions

Rather than packing up and moving, you can simply build on to your home and enjoy the extra room it provides. The perfect option to improve your home, a house extension can be either a single-story extension to provide extra space for living or a two-story extension to provide more sleeping quarters.

The answer is conditional on the length of your extension. In light of recent rule changes, extensions of up to six metres in extension can now be constructed under the permissible development regulations without the need for a planning permit (or eight metres if your house is detached). A permit would be needed for anything beyond this limit.

  1. Write down everything you’d like to see in your future extension, from bedrooms to closet space to outside patios.
  2. Get detailed architectural plans for the extension that can accommodate your specifications.
  3. Make a request for a building permit (if needed).
  4. Gather bids.
  5. You need to pick a date to begin.

Increasing the square footage of your property or adding new bedrooms will increase its worth.

  • It will take about three to four months to finish a single-story extension.
  • An extension with two stories will require an extra 5-6 months to build.
