I like front entrances for humans rather than cars.
I like there to be a floorplan that doesn’t just have one path through it… I want there to be at least one O path, preferably one per floor.
I like balconies and turrets and ledges to sit by windows, and built-in shelves, walk-in closets other closets, etc.
I like interesting floor plans and prefer not to have cavernous vertical spaces.
I like full height basements rather than crawlspaces.
I like circulating heat – being able to send the hot air upstairs down to the bottom, radiators, and cycling heat from the roof and attic down through the house for efficiency.
I like solar panels.
I like glass-enclosed spaces and porches and/or balconies with roofs so you can be a bit more outdoors while still having shelter from rain.
I like laundry chutes.
I like places where cats can have litter boxes and food and places to sleep/hide and ways to get in/out, without being a problem.
I like having enough hot water and water pressure, and having accessible not-too-annoying water filters, and having my own well.
I like having few/quiet neighbors and access to woods etc.
I like sky lights that are tubes up to a light collector that gives good free light during daytime.
I like having separate enough spaces that multiple people can do things and entertain themselves separately without having to hear or be aware of each other.
I like having drainage that doesn’t go into the basement (e.g. French drain), and accessible gutters.
A backup power generator could be good.
