What do fractals have to do with architecture? The fractal geometry of nature is directly visible to an observer when traveling in mountainous regions. One often can not tell for sure if a peak is close or far, a mountain very tall or only somewhat tall. Where there is no scale to measure the landscape, it can be very big or very small. Part of the incredible inherent beauty in Frank Lloyd Wright's small houses is precisely this fractal quality. Small form details in the trim, furniture, and masonry, repeat at larger sizes and in some cases even in the diagrams of the floor plans and sections. He even experimented with letting the forms extend into the landscape to some extent.

One could say that a fractal house design would have a quality that when you looked at the forms and shapes in the details of the building, they were mimicking or similar to the larger forms of the rooms. And of course if a building related to the landscape of the site, it might well pick up on forms and shapes inherent in the landscape and then find ways of working with those similar forms in the building.
