Inhouse staff are available on-site to give you a guided tour of a recently completed granny flat in Sydney and can explain all inclusions in a simple and easy to understand manner.

We believe it is important to see and feel what we use so that you can make a confident decision.

We were amazed at the ease of the build, how they were able to be so flexible, and the great communication and professionalism. The granny flat looks great and rented within a week of being built.
