Hospital space planning: what happened to all the magic numbers?

"Magic numbers" and user "wish lists" have traditionally been used to determine space needs in health care institutions. Today, however, combining functional and space planning to yield a space program that integrates with the facility's long-range strategic plan can be accomplished through a user needs approach. These three approaches are discussed in light of their positive and negative aspects and their contributions to the planning process. In particular, a methodology for examining a department's potential "space generators" is provided. Along with this methodology is the reasoning behind beginning the detailed analysis early in the planning process.
