Architectural means to do with the design of buildings. How they are planned, not how they are built.
It attaches to drawings, styles, features and salvage, and architectural salvage is a whole trade in reclaimed doors, fireplaces and stone. The word also describes anything with strong structural form, so an architectural plant has a bold shape and an architectural cake is a compliment about its engineering. The noun is architecture, which computing has borrowed entirely for the design of systems.
