There is lot of things that I would love to do.
First, I would get a room for the babies and one for the adult in case it's not already planned.
Then I would get an incubator room. (Take a look at Corey Woods one, nearly perfect).
I would also get lot of tools easy to use and lots of alarms to know what's going on exactly.
I would get power outlets everywhere I could with lot of breakers. Just to be safe, you could isolate anything exactly where you would want to. (And make down everything).
I would also get water just about everywhere. I would put stuff on trolley or water coming from the ceiling probably.
I would also get ceramic all over the place and some water overflow in the floor.
For heating and cooling, not sure on what I would choose yet. Depends on the wearther anyway, and it's pretty cold all year around here in Canada compare to Florida.
Last thing, I would want automation nearly everywhere.
I would put lot of money into building a last tech /automated warehouse.
Put alarms for theift but also for heating, cooling, water breakage etc... You want to know exactly what's going on there, anytime of the day/year.
Don't forget the internet/wifi and probably some TV stuff.
