Single tree building residential project is located in Kermanshah. The design of the building is modern and at the same time we have tried to create a sense of vitality for residents and pedestrians. On the building is 12 meters, we have achieved a 1 * 1 pattern with the desired distance according to the vertical lines we have drawn. We have designed a four-meter square with white brick material, behind which is the kitchen, which has been added to its visual appeal by moving this box in the facade.  The design of the 2-meter balcony is given to the whole facade, which residents can use if needed. The use of aluminum shell in front of the balcony is due to the creation of privacy and the use of a cross design on these shells to play with light and shadow indoors. The design of the balcony in the bedroom for the view and the surrounding area and a tree in the balcony were considered to make the space more beautiful, as well as a space for root growth and water drainage.
