This frame is made out of three same unit so it can move later. Due to moving, I made it to 12×12 in size. To maximize the floor space, we made bunk bed and good storage space at the 6 feet and 7 feet high. Also making window with nook to utilize space. Window was purchased from Wayne Morstad at Colbe window 250-215-3292. I asked if he has any left over window and they did have one cancellation of the windows that I could use 90% of what they had. Very helpful and knowledgeable parson, I will recommend any one to contact him for any windows also folding windows.
