Interior Space and Exhibition Design Qing Zhu Lake Sales Center by WenLi Wu QingZhu Lake is a sales center in ChangSha that also serves as a small library. The interior covers 1200 square meters and is finished with marble, glass and wood flooring. Surfaces are shaped to recall the pages of an open book. The quiet setting invites visitors to read and to return to printed books, as many young readers now prefer electronic ones. The intent is to give the building value beyond its basic sales function. The calm reading atmosphere is meant to encourage reflection and to leave a lasting memory.
