Combinatorial is another sub-topic and sub ordinate of Golden Mean theory. This paper is part of on-going research of modular construction system (MCS) in Malaysia. Objectives of the research were to propose an appropriate scheme and concept for sustainable design for modular home based on research findings.The researcher conducted case study (Personnel Expert Interviews) to collect data of MCS in Malaysia. Proposed combinatorial design for spatial planning of home design has been carried out by the researcher at the end of analysis as design experimental yet need validation from computer science experts. Combinatorial in modular architecture is the theory of conceptual design for future building design process of MCS. The researcher discuss in details and to clarify the proportion combinatorial for MCS in aspect of building forms and arrangements through proposed combinatorial formula. In Malaysia, design technique should relate to local culture, weather, and available materials sources as mentioned by the experts. Combinatorial design of modular architecture is an alternative design for compact affordable home. This combinatorial geometry (3D module) repeated, duplicate and can be oriented in a few ways to forming combinatorial models of building design. Pattern A and B are considered to be the best in economic aspects and practicality in term of shape of green. Proposed concept possibly can improve user decision making (digital design process) e.g. building players to plan their building lifecycle projects in term of economical design, green shape, reduced construction time and cost. Thus, it may be able to promote user friendly design, fast track construction, and quality based product, less wastage and varied of design selection can be chosen of the user.

Healthy housing is a fundamental element for healthy community. It ensures the availability of safe, decent, and affordable housing that supports the health of its occupants. In addition, people spend more than 80% of their time inside the house. Unhealthy house can cause many diseases, health problems, injuries and many more. The aim of this research presented in this paper is to provide an information on the effective interior spatial planning where obviously it will impact people health and contribute to healthy living environment. The reasoning for this research originates from the perspective held by researcher that the place where we sleep, work, live have an impactful factor that will determine our daily basis health. To accomplish the target a blended method was utilized. The technique adopted incorporate questionnaire with homeowners including the case study of the chosen healthy home construction in Malaysia. Healthy home approach is not noticeably where some studies have conducted in Western countries in the field of medical healthcare. Thus, there is lack of deficient data in the field of built environment particularly in our developing countries. This research also seen as important in the wake of recent endemic COVID-19 that involved wellbeing inside house. Future investigation is necessary due to pervasive and recurring interior spatial planning deficiencies that can be drawn from this research for health fairness within the society and nation.
