Wire the shit out of the place.... you can never have too many power outlets, ethernet jacks, speaker ports, or coaxial cable outlets. Run everything you can through conduit so you can future-proof the place and run additional wire when needed. Don't daisy-chain the outlets if you can help it. Run everything to a central utility room that's large and well ventilated enough to hold all of your backend computer shit. Don't just shove it into a closet, give yourself some room to move.
Put in recessed lights and speakers in the ceiling for all the rooms and put in multiple zones for different zoom designs and activity patterns.
Think about where you'll spend most of your time and put the house's thermostat there so you'll be most comfortable. If your furnace/AC can handle zones make sure you think hard about the best placement of the other temperature units.
Buy an LCD and place it behind two-way glass in the bathroom so you can get a pop-up display of the weather or watch local news in the morning while you brush your teeth or pee.
Hide speakers and video cameras in the walls/floors and connect them to a hidden computer that broadcasts out to the world on a concealed SSID. Then, when you move prank the new owners and make them think the place is haunted. Don't do anything overt, let subtlety be your friend. Creaking floorboards, a door closing, quiet footsteps that follow along and move from speaker to speaker, and ultrasonics for the pets. Record everything if you are feeling really illegal about it and then stitch it all together and post your movie on YouTube.
