Arranging to open up space in the house

I'm re-arranging so I can convert a little space in the house to a studio. Our little library will soon be changed. Moving bookshelves upstairs to open up window space. I'd like to use the open window as much as possible for light (with reflectors), then I can use my studio lights when it is dark. We'll see. It isn't a huge room, but I think it holds potential for mini-sessions especially geared toward kids and babies!
