In the building industry the term ‘home extension’ means to extend an existing property. Basically, it means to add another room/s or make a room larger, giving your home more living space.

We cater for both single and double-storey home extensions. Each is custom designed and built.

Every home extension is unique. A time frame will be devised based on the requirements for your site preparation and home design. Usually, the on-site build time ranges from 5-10 months?

Any structural changes to your home extension should be made during the design phase, not construction. During construction, however, minor changes to things such as the layout of your fixtures or cabinetry are easier to do.

All our home extension designs are rated 6 stars for energy efficiency. If you have specific materials in mind, you can speak to our design team too.

A bank or mortgage broker can assist you with obtaining finance for your home extension.
