A bay window is a window space projecting outward from the main walls of a house and forming a bay in a room, either square or polygonal in plan. Such windows can usually be found in quite old buildings but some people use them in contemporary homes too. There are different ways to use this space. You can simply leave them empty in order to enlarge you living space or make this space a comfy working space, reading nook or something like that. Here is a gallery of ideas that will help you find the best option for you. Enjoy!
