Convex windows do not calculate the area. According to the documents of the Ministry of Construction, the area of houses with non-vertical walls such as inclined arcs and parts with a height of more than 2.2 meters shall be calculated; If the house wall inclines outward beyond the outer edge of the bottom line, the building area shall be calculated by floor projection. In other words, the bay window with steps, as long as the height does not exceed 2.2 meters, is not included in the sales area. In other words, the height from the floating windowsill to the ceiling is less than 2.2 meters, and the windowsill is not included in the area. The balcony of the building should be calculated according to its horizontal projection area 1/2. Bay windows are usually rectangular or trapezoidal, protruding outside, with glass on three sides.

Bay windows are usually rectangular or trapezoidal, protruding outside, with glass on three sides. There are two kinds of convex windows: external wave convex and internal wave flat concave.

Generally speaking, windows are made on the vertical plane of the wall. If the window sticks out of the wall, it will become a bay window. Nowadays, the popular bay window can be generally divided into two forms, the first one is with steps, and the other is French window.
