I've got a room that we hung drywall in today its 16' x 52' with 8 foot ceilings. About 2/3 of the way down the one side theres a 7'w 2' d stone chimney coming up through. Now that the drywall is up it feels like a damn canyon. When this all started she was talking about post and beams and all kinds of restored barn stuff. I havent talked to her yet but i need to break this ceiling up, its just to long and flat. I thought about doing a coffered but with the 8' ceilings im afraid it will get to low feeling. Say if i come down 5 inches 3.5 for the inside of the bottom beam and do a bed moulding around the ceiling inside the boxes look right? Im afraid that im at a fine line between the effect being too small in such a large room and creating a cave effect.
