I would finish the work on the house to make it a better living space for our family, buy a used car (right now I share one with my husband), put enough aside for the kids college funds and a little for emergencies, and donate the rest. I don't really want a ton of money and new things, I like our life how it is and there are so many who live without basic needs.
Pay off our debts, build my dream home (modest but technologically advanced) , get a nice new car and put money away for my kids for college. I would donate to a charity and help out my sis and brother and 3 of my best girl friends. The rest goes into savings or investments so I could live off the interest.
