Animals: Not obviously easy to achieve in a built environment, but aquariums, gardens, animal feeders, and green roofs provide interaction with animals which promotes interest, mental stimulation, and pleasure.
Weather: Weather can be observed directly through windows and transitional spaces, and promotes awareness and mental stimulation.
Natural Landscapes: Landscape can be incorporated into buildings through ‘borrowed’ landscape, i.e. views and vistas of exterior landscapes, and/or direct interactions such as gardens.
Fire: Somewhat difficult to incorporate into a building, although anything is possible with a carefully considered design. Fire provides colour, warmth, and movement, all of which are appealing and pleasing to occupants.
