Congratulations to the team for their great achievement!”

Gabriela Louie

“Smart Choice Granny Flats delivered us a beautiful 2 storey granny flat. I knew nothing about granny flats when I first spoke to Faraj at Smart Choice Granny Falts. He helped me through the whole design process suggesting what was best for our site. We then had the fantastic builder Stuart Ferguson who made sure everything went to plan. At all times through the process the office staff, especially Chris and Suzanne were prompt and courteous replying to my questions. The end result is outstanding and complements the space available. Being two storeys it means the tenants have much more land available for their BBQ and outdoor furniture. The tenant moved in the day after the occupancy certificate was issued paying $650 per week. Even the real state agent wanted to move into the stunning Granny Flat created and built by Smart Choice Granny Flats. I would definitely use Smart Choice Granny Flats again.”


“I had a great experience having Smart Choice Granny Flats built my granny flat, BEST granny flat building company, 10/10!!!”

Wen Yu Chien

“I consulted with the manager about building a granny flat. He was a very honest man who had been very careful to check my contract and site plans. He was a man who could be trusted by anyone. I strongly recommend.”
