Case study of the flexible unit floor plan in the multi-unit housing development-focused on SDP cases and modification by consumer analysis
In these days, the multi-unit housing market has been moved from the "supply-side" to the "consumer-side" and the consumer demand for housing diversity has been increased. Accordingly, various ways of multi-unit housing development should be considered to meet the homebuyer demand effectively and successfully. The homebuyer demand can be classified into two parts. One is the external conditions comprising location, surroundings, community and neighborhood facilities, schools, feasibility of habitation, etc. and the other is the internal conditions including unit floor plans, quality of specifications, interior finishes, amenities, landscaping, etc. In relates with the internal conditions, the homebuyer's discontent with the conventional unit floor plans, which are not easy to customize or modify beyond surface finishes and usually cause a lot of budget, time, efforts, and industrial waste to reconfigure spaces, can be withdrawn by the flexible unit floor plan designed with consideration of the human life cycle that includes the addition, growth, and departure of children, elderly relatives, or domestic caregivers, not to mention changes in occupants’ interests and needs. Eventually, homebuyers will take the flexible unit floor plan that more readily adapt to their changing needs.
In conclusion, the discriminative and flexible unit floor plan can promote housing sales and generate the successful outcomes of the housing development. Therefore, this study intends to showcase the effective and flexible unit floor plan concept by analysing the process of unit floor plan development, surveying the development cases adopting flexible unit floor plans, finding problems, and improving them.
