Key ideas in How to Read Buildings
- A floor plan is not a bird's-eye view from the sky; it is an imaginary horizontal cut taken roughly four feet above the floor
- Cutting at roughly four feet slices through both window openings and doors, allowing an architect to show how people move and where light enters on a single drawing
- Architects use solid black or dense hatch fills (often called poche) to signal heavy, structural load-bearing walls or columns
- Thin, unfilled lines represent lightweight partition walls that merely divide rooms without holding up the floors above
- The curved arc on a plan traces the physical path a hinged door travels as it opens
- Architects orient door swings deliberately to guide the path of travel and frame what an occupant sees first upon crossing the threshold
- Architects draw straight sightlines through plans to map what a person can see before walking into a room
- Aligning openings like doors and large windows establishes instant visual depth and connects different zones across a home
- Open plans minimize interior walls to create long sightlines and communal feel, but offer less sound dampening
- Cellular plans use dedicated rooms enclosed by walls to provide acoustic control, privacy, and clear boundaries between activities
- Architects deliberately lower entry ceilings to create an intimate, tight physical squeeze called compression
- Stepping from a cramped entryway into an open, high-ceilinged room produces a dramatic emotional feeling of expansion and release
- The perceived size of a room depends heavily on the space you just walked through
- Straight hallways and aligned doorways urge people to march briskly toward the far end
- Wandering or zigzagging paths force the walker to slow down and notice individual alcoves and surfaces
- Architects design floor plans to control the pace of footsteps, not just provide access between rooms
