When my youngest daughter doesn't get what she wants she likes to pout by rolling herself up into a little ball. As a parent I can be frustrated by this behavior but as an architect I cannot help but be impressed. When Darcy tucks her head into her knees and tightly hugs her legs she is making a space that blocks out the outside world.
In a very fundamental way she is creating architecture.
Seeking shelter is an innate human desire. At its core architecture is about creating that shelter: keeping the bad things out and the good things in. That shelter can be created with wood and steel or arms and legs. That shelter can protect you from the elements or from a bossy big sister.
