On top of a classic limestone fronted townhouse at 74 Beacon Street (“The Benjamin Mansion”) right here in Beacon Hill in Boston is kind of the last place you’d imagine an infinity pool, but this set-up is not too shabby. That swanky rooftop view does not come cheap, alas, as this 8400+ square foot, totally renovated, historic home overlooking the Public Garden will cost you $14.9 mil.
