Understanding Bay Window
Bay windows have been used in architecture since the late Medieval period and became a defining feature of Victorian and Edwardian homes in the 19th century. The structure projects from the wall and rests on a foundation, corbels, or brackets, distinguishing it from an oriel window which is supported only by brackets on upper stories. The classic bay window has three panels: a fixed or picture window in the center and two operable (often casement or double-hung) windows on the angled sides. This configuration allows light to enter from three directions, dramatically increasing natural illumination compared to a flat window. Bay windows also add square footage to a room's usable floor space — typically 4-8 square feet depending on the projection depth.
Bay Window in Interior Design
Bay windows create some of the most desirable interior spaces in a home. The alcove they form is a natural spot for a built-in window seat with storage underneath — one of the most coveted features in residential design. In living rooms, bay windows become reading nooks with cushions and throw pillows. In kitchens, they create bright breakfast nooks. In bedrooms, they provide a sunlit sitting area. Window treatments for bay windows require special consideration: individual curtain panels on each section, a continuous curved rod, or Roman shades that follow each panel work best. The deep sill created by the projection also serves as a display ledge for plants, books, or decorative objects.
