The house was from Boutique Homes. You can compare the plans below. The Langdon is on the left.
The overall house size was exactly the same. The difference seemed to be in a slightly smaller living area in the St Tropez to allow an addition of a home office. The kitchen was also a little smaller and didn't have the corner bench top leading towards the laundry.
With our interest peaked we decided to take a drive out to the only display in or around Melbourne in Clyde North (around 1 hour 10 minutes away).
