Mega-mansions are common in South Barrington. For example, it’s not totally out of the ordinary to find homes that are over 20,000-square-feet in size in this Chicago suburb. However, this one on Star Lane is just a mere 11,600-square-feet with a six-car garage set on two acres. The home was built in 2008, so it’s a relative new entry to the mega-mansion inventory in South Barrington, but it can be yours for $2.899 million. There are six bedrooms, eight and a half bathrooms, and other luxury amenities like a theater room, basement bar, and a home office filled with walnut. The taxes on a place like this? You’re looking at $40,000 per year.
