World's most expensive square footage

While I think I'll save my pennies for a down payment on a house I might actually be able to wiggle my toes in, I can't help but marvel at the ingenuity and artistry behind these little "dream houses" by Philippe Tournaire. And there's a nice story behind them:

Les premières bagues architecture furent découvertes pendant l’ère Mérovingienne (VIème siècle après Jésus Christ).Ces bagues ont pour la plupart été retrouvées en Gaule, enfouies dans les tombes de femmes mérovingiennes appartenant à la haute aristocratie. On appelait ces bagues « bagues de la foi ».
Au XVIème et XVIIème siècle, on retrouva également des alliances juives datant du Moyen Age, ornées d’un petit édifice qui symbolise à la fois la nouvelle maison du couple et le temple de Jérusalem détruit.

The first architectural rings were discovered dating to the Merovingian period (6th century A.D.). These rings were primarily found in Gaul, buried in the tombs of Merovingian women belonging to the high aristocracy. These rings were called "bagues de la foi" (or "faith rings").
In the 16th and 17th centuries, Jewish wedding rings were also found dating from the Middle Ages, decorated with a small building that symbolized both the couple's new home and the destroyed temple in Jerusalem.
