I bought the Stones' Throw venue yesterday. I don't really want to place the venue(don't even know how)but you're supposed to be able to build greenhouses with the glass roofs. My question is...how? I've never built a Sim house in my life(apart from a very boring shed with a very boring roof that led down into the basement). Do I just do as I did with the shed? Build a square wall, put tiles on it, then the glass roof? So confused! I've wanted a greenhouse for ages, and with Seasons coming for me on Tuesday, I'll need a safe place for my plants.
