This was planned as a prototype for a four person-residential housing unit that could possibly be merchandized by adding a second floor and increasing the area by 115 square meters. Although it is a two-story building, the construction method remains the same with that of a one-storied house. Using the same procedure, furniture is placed on top of the second floor that had attained lateral strength. Rug-screws were then placed to stabilize the furniture and the floor beam. As for the units, modulars were not changed but instead a new variation of sink, kitchen, staircase, and closet with an interior air conditioner was added. Finally, the plan’s variation was greatly broadened by adding individual furniture-less wall units.
