contest answer.

First, thank you for the interest and the guesses. (Many of you have shared your guess in person.) We are honored by the interest people are taking in our dream-come-true house.
No one guessed the correct answer.

THE ANSWER: The second set of lines on the floor around our queen-size bed - which is a 10'6" square by the way - is the size of our current bedroom!

I can't even photograph our new bedroom in a way that shows how spacious it is! And let's just say, we will appreciate the room. I already daydream about sleeping here with the balcony door open to the fresh air in the fall and winter. (The original screen door is being re-screened almost as I write this.)
