Really happy with the Granny flat built for us. We were are bit concerned due to the all the news around delays in construction projects and I am really glad we decided to go ahead with them. While there was a bit of delay but I am happy it was all done within a reasonable timeframe. The team were very helpful and I would highly recommend them

As a business owner in a different industry, I can appreciate when a company can streamline there trades to complete the works required in a narrow timeline and if delayed to communicate a reason for such delay. From requiring A1 Granny Flats Services or just providing answers to questions in a more simplified manner, I have been given nothing but professional and responsive service that I would kindly recommend to all family and friends.
