I started looking at other designs in the same Smart Living category and came across the Flagstaff 23 which is a larger house. Almost 2sq larger...
After visiting the display home in Freemans Ridge and asking a few questions to the lady in the office there, we decided on the Flagstaff. The design is more traditional but there are less flaws for our liking. Living room space is much larger and another important thing is the bathroom and WC have windows for ventilation. They're not enclosed like the Manchester.
The only issue with the Flagstaff is the width but we are happy with reducing the width of the house which just means that our entry area won't be as wide.
