Do foam insulation and thank me later. Home water service box so you can turn off each room individually. Use a tankless heater.

Home storm shelter.

Anticipate everything that you MAY want to do later and wire for it. Cable, security cameras, anything extra. Put cable and electric wall outlets high to mount TVs on walls which is common now.
