A huge scullery/walk in pantry for my appliances and food items. The scullery would include a big benchtop, power points and hooks for hanging all my aprons

Extra large kids bedrooms combined with large walk in robes. These would have some form of in built shelving and drawers.

A pool that wraps around the house - ie a lap pool down one size which then morphs into a larger pool at the back. This would be overlooked by an alfresco area that has a built in outdoor kitchen and a pizza oven.
