City living doesn’t often allow for the sheer vastness of a 7,200-square-foot mansion. But for Joe Mansueto it does. Founder of investment research firm Morningstar, Inc., and himself an investor in Wrapports LLC—the group that bought the Sun-Times in 2011 and the Reader in 2012—Mansueto is about a year and a half into the construction of a new castle that will undoubtedly be one of even Lincoln Park’s most impressive. The Chicago billionaire is relocating because, as he puts it, his family outgrew their two-bedroom condo on Michigan Avenue.

Mansueto joked with Crain‘s about the bargaining that went into relocating his family a few miles north, saying, “The deal was if we get a new house we can get a dog. So this was an expensive pet.”
