Things you have always wanted for your home but never had?Watch
Coke cola on tap
First aid kit
Old fashioned teacups
Also a garage with a workout/music room above. I would like one of those 2 door fridges with a water/ice dispenser in the door. So many of my friends have those and it always makes me jealous when I go to their place.
ETA: self-cleaning cat litter boxes.
Decent air conditioning, instead of having to use multiple mobile units which are noisy as ****. You can't install fixed air conditioning in a listed house from the sixteenth century!
Aka, whatever modifications you made to the building can be easily reversed.
Beautiful floor tiles
My own bathroom with one of those big round tubs
Damn now I want to design my house
