ooh... love this fantasy!
Walk in wardrobes in 2 largest bedrooms.
Built-alcove space for wardrobes in 2 smaller bedrooms.
Central full bathroom off landing, though (hate en suite).
Downstairs shower but separate toilet room.
Reach in pantry but not walk in pantry. I'm not much of a caterer and big pantries tend to be cluttered with forgotten food.
At least one more storage cupboard/closet.
Loft space for storage or more closet space.
Office room & a utility room downstairs.
Not open plan downstairs (too noisy).
Lots of light, at least one open fire (or stove).
Huge door garage!
One way to do things is have bedrooms downstairs & living space upstairs to enjoy views.
A wet room could be nice, or design utility room to also work well for dealing with wet/muddy things.
Airing cupboard. omg, love mine.
