I am looking for good examples of hillside housing development for an urban design project in Pittsburgh. The site is the slopes of a certain section of Mt. Washington, the hillside directly overlooking the Three Rivers Basin and the downtown. Because of the dramatic views out from the site it is a very desireable location for new housing in a city that desparately needs to expand its tax base. There is considerable local opposition on aesthetic and ecological grounds, however. The site is hardly pristine since it was extensively mined for coal in the 19th century. The proposed uses are both detached and attached single family houses within an open space system.
I would appreciate it if any of the participants could point me to specific examples (with illustrations if possible) of successful development of steep hillsides that integrate environmental concerns, visual compatibility and real estate imperatives. I am looking for these examples to use at a public design charrette as part of the educational process for the participants.
