The standard flat ceiling can actually be just as beautiful as some of these fancier ceiling types. Keeping it flat is something you probably want to do if you don't have particularly high ceilings, as adding trays and beams can make it feel even lower. As seen in this living room designed by Arent & Pyke, a striking pendant can jazz up a basic ceiling, but you could also go for a high-gloss paint or patterned wallpaper.
