An immensely vast room with a high ceiling can look hollow and vacant if not decked up properly. Unless you have proportionately large furniture and decor to go with the room, experts inevitably end up advising you to lower the ceiling height. There are two ways to go about this. You can either reduce the ceiling height for real, or you can create an illusion of a shorter ceiling.
Reducing the height for real
False ceiling, tray ceiling, box beamed ceiling, suspended ceiling systems are all options to lower the ceiling height. Lowering just part of the ceiling will also help you create zones. This method can be used as an alternative to rugs or furniture for zone borders. This will help separate an area for whatever purpose you desire.
Visual illusion of a shorter ceiling
Here, creating beams is a great idea. This will create the appearance of a lowered ceiling. Another option is to play around with the color scheme of the room. Try using darker hues for ceiling. If the flooring matches with the ceiling, this is a bonus. You can also try painting only part of the ceiling.
Hanging horizontally wide pictures at a lower level will also create an appearance of a lower ceiling. Also make sure to avoid decor or furniture with vertical strips. Vertical strips tend to create an elongated feel. Another thing to avoid are long, dark curtains. Use short, sheer ones to make a spacious room look more cosy.
