Coffered ceilings date back to Ancient Greece and Rome, where they were used to reduce the weight of stone ceilings. They were aesthetically pleasing and thus continue to be seen in the modern day. In a new home, the coffers (the boxes) can be framed out with the drywall being installed after, and the crown being installed at the end. If coffers are to be stained, they must be made completely out of stain grade wood. Coffers can have multiple levels and incredibly elaborate designs. Head to Pinterest for more inspiration.
