An entirely new type of house, known as the prodigy house, began to sprout and proliferate all over the countryside. Such houses were almost never less than three stories high and sometimes four, and they were often staggeringly immense. The most enormous of all was Knole in Kent, which grew and grew until it covered nearly four acres and incorporated 7 courtyards (one for each day of the week), 52 staircases (one for each week of the year), and 365 rooms (one for each day of the year), or so it has long been said.
