Here's a plan from the house, it's not the latest iteration, but is close.

It is loosely based on Frank Lloyd Wright's very first "Usonian" home: that of Herbert Jacobs, of Madison, Wisconsin. Built in 1937. Here's the official web site: http://www.usonia1.com
That house is generally held to be one of the pivotal house designs of the 20th century. FLW made several innovations with this home:
1) World's first "Carport". He invented the word, and described it thus, "An automobile is not a horse, and does not require a barn." You can imagine that back in 1937, the car industry was just starting to be able to make cars which didn't leak like crazy when left in the rain.
2) First domestic dwelling to ever have underfloor heating of the concrete floor slab by way of steam pipes. Several banks refused to fund the building of the house because of the "radical" heating solution. FLW called it "Gravity Heat" - and it did work, but nearly so well as he claimed it did. The pipes were buired in sand, totally below the floor slab, when they should have been inside the concrete. Instead of pumping hot water through the pipes, he pumped steam - and at that time no one knew that steam (unlike water) follows the hottest pipe. So, it took many many days of constant heating before the floor was an even temperature.
3) It was one of the first house designs where food did not "magically appear" from some hidden kitchen: the housewife was treated to a kitchen which was the central hub of the house. Unheard of in the day.
Anyway - Emma and I are looking forward to the building process, and only hope we can afford all the features of the home! Wish us luck.
