Basic framing of the walls is about 75% done.

Suddenly, the house appears. It's all just 2x4s and some plywood sheathing: barely a sketch at this point. Even so, I can see it. I can walk from the kitchen to the living room, out onto the front porch, then into our bedroom. I can see where the walls are, where we'll be walking, what people will see when they come in, what we'll see when we look out the windows.
