Parallel to time,the building is constantly growing and transforming. PL-T is an architectural design organization and also a concept. In practice,we focus on the relationship between the durability and the evolution of the buildings in the design,to enhance the quality and the vitality of the buildings and citys.At the same time,the core that design should focus on is to explore people's ordinary life,we hope to design a space that most closely related to people's daily life,as the most "USUAL" space. Each design is based on the reality of life and reflects different social demands.
