Fallswood in Falls Church is a small enclave of funky early 1970s contemporaries with Swiss/ski chalet lines. The neighborhood of roughly four dozen homes right between the Beltway and I-66 was designed by the architect A.G. Mumma and built by R.J.L. Associates. From what I can find, Mumma spent much of his career in the Navy. Here is one house in the neighborhood currently for sale for $749K. It has a very steep roof line with flat-roof carport for contrast.
