What is a Bay Window?

A bay window is a window space that projects outwardly from the main walls of a building, forming a bay in a room, either square or polygonal in plan. Bay window corners usually use angles of 90, 135 and 150 degrees, but other angles can be incorporated into the design. Bay windows are most often associated with Victorian architecture, as they first achieved widespread popularity in the 1870s, towards the end of the Victorian period.

Why are Bay Windows commonly used?

The windows are commonly used to make a room appear larger, because of the extra space, and opportunity for light to enter the room, that these windows provide. They are also used to offer additional views of the outside that would have otherwise been unavailable with an ordinary window, and can be accepted as a more sheltered alternative to a balcony. They are often designed with window seats so that people can sit in the windows and enjoy the views. It is perhaps for these reasons that bay windows have become popular in areas where space is at a premium.

In 1894 the Building Act regulations in Britain changed so that windows no longer had to be flush with the exterior wall. This meant windows could now stand proud from the facade of the building, which in turn meant that architects in the Victorian and Edwardian period could take advantage of these new building regulations and incorporate bay windows in the design of new homes that were to be built during the period. Larger houses would often display double bay or bow windows.

What styles of Bay Window are available?

There are two basic styles for bay windows. Often the bay windows form a box, which simply juts out from a house. Typically, this box is designed to start slightly below head height, and is often installed over a sink or in a kitchen to provide light and a view without disrupting the overall shape of the property. This type of bay window is common in homes that are being built to a budget, or homes in developments which are being built to a standard plan, therefore making building full bay windows too expensive or inconvenient. In other cases, bay windows are designed as part of a floor to ceiling feature, which creates a nook with in the room, and causes the floor plan to be extended outwardly in the direction of the window. The most common shape for this style of bay window design is a trapezium.
