Is the bay window a building area?

Whether the bay window needs to calculate the building area depends on the floating length and the height difference from the indoor ground. If the height difference reaches 0.3m and the average depth is less than 1.2m, the area will not be calculated. The average number of days exceeds 1.2m, and the building spacing is controlled from the outer edge of bay window according to the horizontal projection area 1/2. The difference between the bay window and the indoor floor is less than 0.3 meters, and the height of the window hole reaches 2.2 meters, which is equivalent to the floor-to-ceiling bay window. The area is calculated by horizontal projection.
