The term you are looking for here is probably site specific art. It most often refers to outdoor art and often includes sculpture, but basically speaking, site-specific art is any art (even dance) in which the artist takes the location into account when designing the piece. Outdoor site specific art can range in design from landscaping (sculpture can be included in this) to building design and architecture.
There is also such a thing as site specific dance and performance art. Like its more permanent counter-part, above, this kind of art takes into account the social, historical, environmental, and architectural background of a place to incorporate depth and meaning into the performance.
