During our recent dining room renovation, one of the features we added to the room was a coffered ceiling. A coffered ceiling adds dimension and texture to a space and is a wonderful addition for high ceilings. A coffered ceiling is achieved by installing wood or fiberboard planks to create a grid pattern. Molding or other decorative elements can also be added to the grid, depending on the look you are trying to achieve. Coffered ceilings are also commonly referred to as sunken ceilings.
