SC House is a private residence that tries to solve the problem of limited land in big cities in Indonesia. This house has an area of 72 m2 located in South Tangerang. The concept of this house is to maximize the needs, comfort, and health of users on a small site to improve the quality of life of users. A common problem that often occurs in a house with small sites is the lack of air circulation and natural lighting. That is because the built area is maximized on the site to meet the space requirements so there is no more space to place openings for air circulation and light. The solution applied to SC House is to leave a space of 2 meters wide in the back area as an opening for air circulation and lighting. Space in the back area is also used as a washing and drying area. With the remaining space available, the kitchen, dining, and living room are centered in one 5 x 4 meters room without a partition. The side staircase area also functions as a courtyard or dry garden with a roster wall, thereby increasing the area of air circulation and lighting. Spaces that are private such as the main bedroom and children's bedroom are placed on the 2nd floor. With the concept of this house, it is hoped that all occupants' space needs can be achieved with healthy and comfortable space conditions to improve the quality of life of its residents.
