The building or public building will be better to have good natural installation. This public place has good installation and small green area that can be used for refreshing in the day. The Natural systems operate in perfect efficiency. This place has complete facilities and the green area is planted with small trees and grass. This public place is designed with the concept of natural and modern. Tres Birds Workshop was commissioned to concept, design and build an art installation in Downtown Denver for the purpose of encouraging people out of their offices for daily fresh air breaks. The green area, although it is small, can minimize the air pollution so that the air will keep fresh in the day and night. The green area is completed with some small chairs so that the people can sit there comfortably and breathe fresh air. The installation made up of part vintage office furniture and part 100% live vegetation reminds us not to let office overgrowth affect a healthy relationship with the outdoors. The installation and green area of this place make good view outside the building.
