Here are some updated Google Street View images of the massive 38,000 square foot mega mansion being built at the intersection of River and Norton Roads in Potomac, MD. It has been under construction for close to two years now. As you can see, it boasts two 5-car garages on either end and it is rumored that there is also going to be a 5,000 square foot guest house on the property as well. Once completed, it will be the largest home in Montgomery County. It has made a lot of progress since we last blogged about in January of last year. I love the symmetry of the exterior and I bet the interior is going to be absolutely divine!
