This project is two-family house, two floors with mezzanine, land size 225 square meters, two land plots, where is located in Neo City Village, Donmuang, Bangkok. This starter home belongs to members of a young generation at the beginning stages of having their own family. For the interior, they prefer a split-level configuration in order to connect every single area in their home and to see each family member’s activity clearly. Also, they would like to have a common space that links their home and parents’ home for arranging gatherings with friends and to use as an activity area. The second home unit was built for their retired parents living in the same complex. The parents did not want a complicated structure, preferring a simple style, ample personal space and a garden.
