This newly built mansion is located at the end of Willowbrook Drive in Potomac, MD. It’s still under construction in Bing Map’s bird’s eye view, but you can see that it’s completed when looking at Google’s Street view. It looks to be in excess of 25,000 square feet and includes two turrets. Potomac definitely doesn’t have a shortage of mega mansions, there seems to be a new one popping up every month! Can’t wait to see what this one looks like finished.
