We explored a few options to suit our requirements, however we kept coming back to Hypercuby. it made the most sense as it was an all in one solution and required the least effort. The only issue we had was that there was a delay in the supply of the special double glazed windows for a window supplier. We worked around this and the communication was great. I have slept many times now in the Flatcuby Plus PIR including in freezing cold conditions and it has exceeded my expectations. It's quiet, cozy in the winter with a small heater and comfortable in summer without the need for an aircon. If you are thinking about purchasing - go for it. The only other thing I can add is to have a friend assist you who is experienced with building and it is possible to build it over a long weekend.

Approximate cost: $13000
