That four piece crown was a strip of 1/2x3 on the ceiling and the wall, the actual crown molding, then a hounds tooth on the wall. The room was 16x30 with a 12 foot ceiling. I also built in a floor to ceiling bookcase/china cabinet on one end, recessed into the wall and converted a useless closet into another china cabinet, with glass shelves and recessed lighting, on the long wall. Wainscoting with a plate shelf and a three piece baseboard. Even the door moldings were three piece. That whole project, which involved adding joists in the room above to level the ceiling, adding framing in the walls, jacking the floor to level that and installing all new windows, took a year. Oh yeah, I pulled the floor boards, which were ship lap, and refinished them as well. It ended up in a local magazine, really came out well but was a real bear and a major headache.
