I had a home studio but the room was just too small. So I am renting a space now. Even though there are windows I don't do natural light.
My setup is as follows:
1- Extra Large Soft box
1 AB400 (alien bees)
Here you can see the studio setup http://www.elzeephotography.com/2011/09/the-studio/
the only thing is I moved the lights around.
