Therefore, the strategy was to create about 1-meter wide void spreading throughout the house that calculated to maximize natural ventilation and lighting by allows them to go deeper into the house interior so that most of the rooms was lid up during the day and cooled down in very typical hot and humid tropical urban climate of Southern Vietnam, as the result, energy consumption for lights and air conditions will be minimized.
Located at the ground floor was a small garage enough for at least 4 motorbikes - a very common traffic means of Vietnamese - and behind was a small living room mainly for guests or can be used as a spare room for the future's needs. A precast concrete staircase on the left side goes independently straight up to the first floor (or mezzanine) where kitchen, dining room and a family room located. 3 functions were packed in a quite small space (due to the construction certificate that the first floor or mezzanine has to be receded from the construction line) but still designed to be very cozy and comfortable.
