Other things:

- tankless water heater

- if you want motorized blinds, have wiring go right to the window frame. You can do a battery otherwise, but you’ll have to recharge it every month.

- solar cells and battery pack

- home automation system (if you’re into that kind of thing)

- timer switches on bathroom fans

- bathroom fan in your laundry room

- hidden safe that’s built in (eg in wall or in floor)
