An overall good result with the Extention factory. From the get go we shared the same vision with the design and preliminary drawings, great stuff. The building timeline however was a long ride, engulfed with tradie shortages which postponed the build. Ultimately the build was sound and exactly what we had expected. We would not hesitate in recommending this company to others whilst initially ensuring you have an agreed timeline outlined to avoid any unexpected delays and heartache.

Thank you Matt, you have been a great client to work with, hope you & the family enjoy all the extra space for years to come! We really appreciate your patience with the unforseen delays.

Ignore the dozens of fake 5 star reviews and visit their Google and Facebook pages. Avoid at all costs, terrible experience.

OVER a year AGO

Really good appointment. Your designer gave us some great ideas & was very helpful. We have been considering renovating for the last few years & were very impressed with the finishes at your display home & the quality of the work you do. We are tossing up whether to continue with the renovation idea or as you suggested looking at knocking our home down & building a new home in its place with your new homes division. Thank you for all your guidance & look forward to getting started soon.

OVER a year AGO

After 2 years the project is still running, inconpetent tradies, project managers and executives.
If you use this company you will realise the "Extension Factory" maning: they add an extension on every estimate, delivery date

OVER a year AGO

Thank you for your feedback & we understand & apologise for the frustration you feel due to the unforseen delays with your extension. At the recent site meeting with our Operations Manager an updated timeframe to complete your project was agreed to and has been adhered to & met. We hope that you will now be able to enjoy your new home extension for many years to come.
