This study proposes an ergonomics-based approach for those who are living in small housings (known as flats) in Indonesia. With regard to human capability and limitation, this research shows how the basic needs of human beings are captured and analyzed, followed by proposed designs of facilities and standard living in small housings. Ninety samples were involved during the study through indepth interview and face-to-face questionnaire. The results show that there were some proposed of modification of critical facilities (such as multifunction ironing work station, bed furniture, and clothesline) and validated through usability testing. Overall, it is hoped that the proposed designs will support biopsychosocial needs and sustainability.

Rusunawa Penjaringan Sari 3 is flats owned by Surabaya City government with capacity 99 units. The current motorcycle parking lot has a total area 185.61 m2 and the parking slot dimension is 2 m X 0.7 m. It can accommodate 100 until 145 motorcycles. This limitation space makes motorcycles must park randomly and irregularly, such as parking at the space for people walking and parking in parallel that can block a motorcycle that wants to go out. Improvements that we did for parking layout in this research is based on parking standard, published by Indonesia Directorate General of Land Transportation. Each motorcycle has parking alternative slot dimension 2 mx 0.85 m and the aisle width is 1.6 m and double way. Using simulation approach by ProModel, we developed 4 alternatives and compared them. The average time for residents to de-park until leave from parking space motorcycles decreased from 56.118 seconds to 17.342 seconds (alternative 1), 17.2273 seconds (alternative 2), 21.986 seconds (alternative 3), and 17.242 seconds (alternative 4).
