In practice, the assignment for RoarcRenew is to design a shared living-room under a 10-m high ceiling inside a female-themed shopping mall.

The edge of the original floor is “softened” and the edge facade forms a "welcoming" curve. It provides a place for "seeing" the "butterfly" space. The new elliptical staircase connecting the vertical traffic of 4th and 5th floors provides an important channel and a main visual image for the whole field.

In this "butterfly", we used 44 steel pipe arch rings to curve a series of multiple arches in accordance with the original floor shape, and constructed the original vertical structure of the site -- the clock tower outward central array.

We spent half a year trying to study the necessity of putting the membrane structure into the indoor space, construction, building order, joint connection, lighting coordination, structural load, etc. As a result, we are excited to see that the soft "skin feeling" derived from "membrane" materials forms a special media carrier. This is complemented by our desire to express the "charm of butterflies" of “women”.

"Membrane" functions as a good thermal insulation and it is the regulator of indoor microclimate.

After the design, the art zone is equipped with a gallery, indoor children’s castle, parent-child library, and a small stage and an auditorium, all of which will grant the Joy City a sense of community center and an enjoyable space.
