Set Up Advice

I need advice on set up...I did lampwork a bead in a room in my house, I had the window open. The sproblem I'm concerned with is the heat that emitted from the room or the fumes for that matter. I live in Miami, I've tried lampworking at night outside but I'm not successful, during the day its too bright to see the flame. Any suggestions for ventilation in a 10x10 room. thank you cathy
