The shape of a window

Working with an architecture that's already been defined sharply narrows the architect-designer's options. But we try to find the upside, treating it as a test of skill. By paying attention to the details and the little things, we reach our goal with small changes.

Here, for example, are a few ways to approach a project at the sketch stage. You'd think you're only changing the shape of the second-floor window, yet it changes the whole look and feel of the house.

The client wants the second option. Which one do you prefer?
