Hsieh says that the fence project had left him with a niggling sense of unfinished business: it was not itself a complete, freestanding piece of architecture, but functioned rather as one part of a construction site. Hsieh wanted to extend the concept of modularity to a complete architectural work. In his view, this no-tools-required sphere does just that, breaking new ground and blurring the line between architecture and industrial design.
謝榮雅表示，設計完圍籬後他覺得有個小缺憾：圍籬是附屬在工地的建築，不是完全建築；他希望能將模組零件進一步延伸成一棟完全建築，而這款不用螺絲、不需扳手的球體建築，打破了工業設計與建築的界線，很有前瞻性。
