Landscape amenities represent an effective way to boost the occupancy rate of apartments and other commercial buildings. People enjoy aesthetically-pleasing areas and are much more likely to choose to live and work in buildings with attractive landscapes, so there is a high correlation between nice landscaping and high occupancy rates of buildings. It therefore becomes more economically feasible to invest money in landscaping because the return in the number of tenants and amount of rent money far exceeds the cost of installing ornamental plants. Owners of buildings should seriously consider landscaping as a means to attract new tenants. (The Danter Company 1993, Frank 2003, Wolf 1998)
