Do Ho Suh tar utgangspunkt i det ytre hjørnet av den hellelagte plassen, der han foreslår å plante et tre. Mellom hellene i dette området, og delvis istedenfor dem, skal det plasseres en stor mengde 8-10 cm høye menneskefigurer i grønnpatinert bronse, som gress som vokser opp. Noen steder presses hellene opp av figurene. Sett ovenfra dannes et geometrisk spill på plassen. Figurene er individuelt utformet, og representerer stor variasjon mht. alder, kjønn, yrkesgrupper og etnisitet. Det er meningen at man skal kunne gå over figurene, og benytte de hevede hellene som sitteplasser.
”I was also struck by the architect’s desire to respect the typography of the slope by taking it into the lobby. (...) For me the continuity of material reflects the tradition of Norway’s institutional architecture. This led me to create a piece about the general public and to respect Norway’s tradition in making something very modest. Instead of designing a sculpture that is vertical and monumental, in the tradition of public art, I decided to follow the slope of the plaza and create something horizontal. At first glance it does not look as though there is anything there. Grass Roots Square is at ground level, the same level of the plaza and the public. It is at this level, the grass roots level, where you can truly understand a community.”
