Housing: Upwards of $32 million
First thing's first: the bachelor pad. If you’re going to pull off the lifestyle you’ll need your very own Tudor Gothic mansion like Wayne Manor. The exterior shots for the latter two films in Nolan’s trilogy are of Mentmore Towers in Buckinghamshire, UK, which was recently appraised by a real estate website for $32 million. Interiors, though, were shot at the opulent Osterley Park House outside London, which would have certainly jacked the price. We spoke to an architect who actually builds these types of homes to weigh in on a set of fictional blueprints (from a slightly different Wayne Manor) and he concurs: "He's got a 1st floor of 8,750 square feet, a 2nd floor of 3,600 square feet, plus his Batcave at 12,000 square feet totals out to 24,350. Total cost has to be at least $1,000 per square foot, so $24,350,000 minimum."
Since we're discussing Bruce Wayne, we're not factoring in the cost of a Bat Cave (or any Batman-related costs).
