An architect knows something about everything. 

An engineer knows everything about something.

An architect is a generalist, not a specialist. A conductor of a symphony, not a virtuoso who plays every instrument perfectly. As a practitioner, an architect coordinates a team of professionals that include structural and mechanical engineers, interior designers, building code consultants, landscape architects, specification writers, contractors and specialists from other disciplines. Typically, the interests of some team members will compete with the interests of others. An architect must know enough about each discipline to negotiate and synthesize competing demands while honoring the needs of the client and the integrity of the entire project. Matthew Frederick's words.

our experience of an architectural SPACE is strongly influenced by how we arrive in it. A tall bright space will feel taller and brighter if counter-pointed by a low-ceilinged softly lit space. A monumental space will feel more significant when placed at the end of a sequence of lesser spaces.
