Hey Aido,
We have just started our build with Metricon and we have chosen the Denver 43. It has been awesome seeing your home being built as ours will be practically identical. We too have made the garage bigger but love your ideas about the cavities in the ensuite as we never really thought about it until just recently. Not sure if they will even accept any changes from us at this late stage as unfortunately, they haven't been as great to us (Customer Service wise) as they sound to be with you. Time will tell. Loving your pics and good luck....
