In most instances, negative space creates the habitable and experiential space in architecture and urban design. I think the trick is to make the negative space even more interesting than the architectural forms. This church by Ciel Rouge Creation is a great example of how the architecture can be used to create an amazing experience. There is an unmistakable form carved out of the concrete, but this isn't an end in and of itself. The form allows light to penetrate the interior and illuminate the architecture and add to it's allure. Even the exterior cross figure is created through negative space, allowing the light to project that image onto the main structure. This should be a reminder that architecture isn't only what we add, but what we subtract.
