Problem
A building is most often thought of as something which turns inward—toward its rooms. People do not often think of a building as something which must also be oriented toward the outside.
Solution
Make sure that you treat the edge of the building as a “thing”, a “place”, a zone with volume to it, not a line or interface which has no thickness. Crenelate the edge of buildings with places that invite people to stop. Make places that have depth and a covering, places to sit, lean, and walk, especially at those points along the perimeter which look onto interesting outdoor life.
