Maison TL is a semi-detached villa renovated to fit the newly-moved family including elderly parents, helper and two young couples.

Therefore, the architectural form must be carefully considered between creating modern innovation, the building must have personality, with unique but gentle contrast and meet general regulations. - Regarding architecture, the façade form of the project is reduced in line. The windows on the façade use a direct sunblock with reinforced concrete woven panels.
