Now That's a Sunspace The Preservationists must have loved this one. This 5,400 square foot glass pyramid is attached to an 1830 traditional home, overlooking the ocean, in coastal Massachusetts. The pyramid opens to the view and among other things provides sunny shelter to a 15x40 foot swimming pool. The glass structure's 71 fixed glass panes face south and east for solar gain, while 23 electrically-operated roof windows let in ocean breezes. Retractable awnings provide summertime shade.
