Tssui believes nature to be an incomparable educator, with knowledge of design and construction borne of the necessary adaptation to constantly evolving systems. Exploring the hows and whys of nature's workings, and looking at the active and reactive relationships of organisms with the surroundings are some of the driving forces behind Tssui's designs. According to Tssui, humans are students of nature, who is the educator. In order to create efficient and sustainable living spaces and lifestyles, architecture must draw from nature to achieve the optimum solution to a given problem. Tssui searches for design elements that work to place the responsibility of environmental and human health back into the daily conscience and behaviors of human life. This outlook must then be expressed in the building's spaces, both interior and exterior, as well as in the detailing and relationship with the site. Tssui also underlines the desire to create responsive buildings which not only work in tandem with and prevent further damage to the environment but also restore damage that has already been done.
