Last year when we looked at the biggest homes on the market in DC it was surprising to see that some of the area's most expensive homes on the list weren't necessarily some of the largest. Not to say that these houses are inexpensive, of course. One of them has already gone under contract earlier this year, the DC Design House from 2011, and now there's another one that has found a buyer. This one, at 8,868 sq. ft., even has its own name. "Normanstone" is a 4 bed, 7 bath house in Mass. Ave. Heights that has been asking $5,995,000 for the past year. That leaves four others on our list just waiting for a buyer.
