We are going to file this under 'out of the box'. Architect Daniel Libeskind was asked by 'a very rich art world couple' to build them a country home and this is what he delivered. We think the couple couldn't have been any happier considering the fact that they had challenged the architect: “Whatever you design, we'll ask you to make it more extreme.” So why the numeric name? Libeskind explains:

The living space of this Connecticut residence is formed by a spiraling ribbon of 18 planes, defined by 36 points connected by 54 lines. This pure and dynamic architectural form generates distinctive interior spaces while dramatically framing both near and distant landscape scenes. Large glass planes virtually disappear within the ribbon, allowing unimpeded picturesque views of 18th century hay meadows and giant oaks. Circulation through kitchen, living, dining, and sleeping areas is seamless and free-flowing, as is the distinction between interior and exterior space. Challenging both traditional and modern notions of “the house in the landscape,” this design gives nothing of itself up to its natural setting, but selectively incorporates the elements therein for the enhancement of both house and landscape.
