Interior Space and Exhibition Design Tranquil Spring Residential Apartment by Kai-Bo Chen The residential planning and design case was for the renovation of a 20-year-old residence where a family of three generations lived. With respect to home repair, designers resolved the water leaking problem, elevated the floor to improve the inclination issue, and mended exterior walls to consolidate foundations of the design. This case also faced the issue of its beams. To work with the crossbeam at the center of the dining room, the ceiling was separated into three equal sections. The major beam was flattened out and was designed into a groove ceiling to beautify the kitchen-dining area.
