There is a house in Santa Monica that defies every notion of the modern contemporary home. Instead of straight lines, natural wood siding, taupe plaster walls, architects John Friedman and Alice Kimm tossed those tenets out the window and came up with a fresh, lively approach to suburban living. Forget neutrals: The exterior, dappled in a chartreuse-and-white pattern, offers the visual enticements of a retail storefront. And forget about the typical floorplan: The main living area and bedrooms look directly out to a busy neighborhood intersection.
