This project was done for a villa house in Karaj city. In this project, the covering of the parking lot and a part of the kitchen, was carried out by bubble skylight. For this purpose, after carrying out the necessary expertise and measuring the dimensions of the bottom surface of the project, simple square bubble skylights and rectangular simple bubble skylights as well as simple triangular bubble skylights were used side by side. The use of blue, green and orange colors created a very pleasant color spectrum of the interior of the project. Also, due to the fact that the surface of the wall was not equal to the surface of the roof and the desire of the client that the wall of the parking lot should be a place for the passage of air and direct sunlight, very strong iron foundations were placed on the side of the parking lot, and according to the request of the client, a side cover did not settle.
