A cantilever construction, is when a horizontal beam extends beyond a foundation wall. The beam is only attached at one end. The beam is stabilized by the weight of the wall. The portion extending freely is called offset. A bay window is a window of three sides that extends beyond the exterior wall of a house or building. The central window is parallel to the wall and the windows can be cloistered or backrest angle, depending on the style of the bay. This window is called a viewpoint as from inside the room takes the form of a bay.

Defining a window bay cantilever

The bay windows have been built for over 500 years. Often, the popularity of this window is increased in conditions where dense housing costs increased land and housing is forced up in order to gain inner space. Thus, the window may project beyond the outer wall providing a bottom cover, additional interior space and additional light to the indoor space.


The bay windows come in many styles, the style of window is called a window box today is simply a version of a box-shaped window. When a window has windows curved, arched window is called. If the outer bay bracket cantilever is brick or stone, it is called a viewpoint. Most windows have three windows , but some have up to five or more.
There are two types common to bay windows and a window often called a bay window which is actually a room without polygonal shaped cantilever windows outside. This third type of window can be set directly on the foundations of the building or home. It rises from the base and is part of the outer wall despite creating a space like window inside the building. The windows have two real overhang beyond the outer wall. Cantilever style will just below the bottom of the window. The other styles are overhangs on the floor of the room with the window.

Overhang at the height of the window
The bay window overhangs directly below the window may suffer from support issues as the weight load of the window and roof window can rest on supports. This style limits the depth of the window and may be somewhat less durable. From inside the room with this type of window, the window will move outside of the exterior wall at or near two feet (60.96 cm) above the ground. More interior floor space is not won, although that was brought in extra light. This window style invites a window seat or space for decorations.

Cantilevered floor height
The cantilevered bay window at ground level room is stronger. Usually, the floor beams will extend beyond the outer wall. This allows significantly more load on the surface which projects beyond the wall. The resulting ventnal can be something greater and, because the floor joists are projecting outward, interior floor space of the room increases. This is substantially better in terms of design engineering stress. It is also more aesthetically appealing on the outside of the building because the windows will not be cut or crushed. When only one window proja outward, glass can make the window area look weak or thin, and the roof of the bay may seem visually pushing down on the glass. The windows at ground level are more frequent.
