Wutopia Lab has completed Sinan Books Poetry Store with the concept of ‘Church in church’ , using 45 tons of steel in the historic site of St. Nicholas Church in Shanghai. As the largest professional poetry bookstore in Shanghai, it offers 1000 poetry books in different languages. A continuation of Wutopia Lab’s design style, magical realism based on antithesis, perforated steel plates, translucent, uncertain light, color and dramatic poetry could be found in the poetry store. Given the fact that the dome could not be transformed, the designer used bookshelf to create a new structure as a Church in the old building Church. This is Church in church, a sanctuary for modern people was born in where once a sanctuary of faith. Wutopia chose to use plated steel plates other than the stone in old site. The partition and stand of the bookshelf are welded as a steel plate grid system. They interact with each other to form an inner space—a poetry bookstore. The bookshelf has no back panel, and the light from the dome can still spill into the bookstore. Different traces from 1932 to 2019 on the wall are faintly revealed through the bookshelf, including the Catholic-style frescoes that the owner asked the students of the Academy to draw when the group was used as a restaurant in the early 2000s. The steel bookstore and masonry church became a new integrate.
