What should i place in my ranch basement?

Nectar ages faster in the basement if you don't already have that set up. I like putting laundry rooms, spare bedrooms, skill rooms, bars, entertainment rooms, and even gardens in the basement if my sims have one.

You might find some ideas in your other thread :blush:
