I'm big into home automation and efficiency so here is my list of things:
- Spray foam insulation
- Nest thermostats
- Keen air vents
- Rachiro sprinkler controller
- Ring.com doorbell camera
- Outdoor camera system
- Dedicated spots upstairs/downstairs for wireless router
- Couple of hard-wired Ethernet spots for Apple TV/Fire TV
- Button controlled light switch (not the flip switch, but a push button. Can put like 6 buttons on one spot, very clean looking)
- Hidden room with built-in gun safe
- Tornado room (use cinder blocks for walls)
- pre-wire for a projector
- Huge sliding glass wall onto back porch
- deck every inch of your attic that you can
Things my wife would want
- Bigger mud room/laundry room (include a sink)
- walk in closets in every room
- Bathrooms for every room
- Small desk in kitchen area to set purse/backpacks on instead of counters
