In this private home bubble skylight project, which was done for the backyard of the first floor of a residential building, bubble skylights were used. The most important concern of the employer in this project was the strength and ability of a person to stand on the cover to wash it. Of course, it is obvious that the water used for washing the skylight, as well as the water from rain and snow, should have been directed to the sewer network without wetting the surrounding environment. After conducting the expert examination, two openable square skylights were placed in the center of the work in milky white color, and for the rest of the work, blue, orange and green skylights were used. In the interior of the work, in addition to the very beautiful colors, the overall light of the building did not decrease significantly and was adjusted according to the client’s opinion.
