A complete lack of communication throughout the project, including how things are progressing, why things are not progressing, or when tradespeople are going to show up.

Progress is promised for one week, then cancelled at short notice because something else needs to happen first.

Tradespeople showing up unannounced, wondering why they cannot get in.

Building materials are delivered months in advance, blocking the driveway, without being used.

Complaints about leaks in the roof caused by building activity are being completely ignored.

Ground floor bedroom, walk-in robe & ensuite extension. Alternative solution for our situation to a granny flat for my aging parents. Sales and design staff were friendly and helpful with our design. The project manager assigned to us (Aaron) was honest, knowledgeable and very accessible. The works were delayed by days due to an unforeseen issue with the doors, but they factored in weather and resourcing perfectly. Extremely happy with the workmanship and what we have achieved overall at the price point we agreed on. Definitely far easier than trying to deal with independent builders as I have in the past.

Approximate cost: $110

Do not use this "company", after contract signing we have endured an extremely stressful time due to complete disrespect and gross incompetence. We were told we could live there during the build but they damaged our existing home so much we (my husband and toddler) had to move out. Our project manager never responded to any of our emails and addressed our concerns just bungled his way through. 4 months over expected completion date. Do not use this company.

Approximate cost: $205

I would like to say that our experience with the Extension Factory was 'all good' From start to finish the people that worked on our project were without exception professional, polite and simply a delight to have in our home. Their expertise, advice and guidance were of enormous help and their workmanship of a high standard. You only have to look at the finished product to appreciate the skill and care that was taken by all of the tradies who contributed to bringing our vision to life. We would like to thank everyone involved from Michael (first contact & co designer) Paul & Michael (project managers) Dale & Max (carpenters) Stefan (plasterer) Jay (electrician) Peter (the staircase Master) the fabulous roofing crew our tiler our plumbers, they were all SO good, a real credit to the company and an asset on any build. Thanks to Alex for his help in the early stages of organising everything and last but by no means least to Angela who worked tirelessly in the office to keep all that paperwork up to date. It has been an incredibly busy and challenging journey but we are absolutely over the moon with the finished product, certainly worth the trip.

Approximate cost: $200000

We had a major renovation by this company. We had a few builders in for quotes but these were the only ones who seemed to listen or understand that we would be living in the house with two small children and that our lives needed to go on throughout the renovation. The whole extension took 3 months and the results were fantastic. Only had one tradie we were unhappy with so spoke to the building manager and the next day we had a new and very competent electrician assigned to us. Great experience. Couldn't recommend this company enough.

Approximate cost: $100k

I had wanted to fix my home a few months ago and hired Extension Factory due to their extensive experience in the field. I'm glad to say that they lived up to their word and all of the work they done was done professionally and with minimal fuss. Would definitely recommend to anyone looking for a good contractor

Approximate cost: $300
