This newly built French Chateau inspired limestone mega mansion is located on Doulton Drive in Mississauga, Ontario, Canada. We posted this home a while back, but now have more pictures of it. At 40,000 square feet it is now one of the largest homes in Canada and was designed/built by Ferris Rafauli Construction. A few interior pics are pictured above.
