The rowhouse is only 3.5 m. width and has water leak problem. Trying to solve the narrow space and utilizing the space to meet the client requirements are the challenging of this project. The client faces the problem of dust so at very first they don't want to have roof deck anymore and ignoring to use it just want to leave as it was. Also in this area the client has the robbers problem therefore they want to cover all windows with rails as a must requesting. We created the facade to cover all windows in stead of using rails to make this rowhouse safe from robbers and unique.
