The house in the middle is supposed to be the Order of the Fenix's Headquarter, or the mighty Black family's lair, if you prefer. The house is unfurnished so you might decor it as you please, but there are all the 7 bedrooms mentioned in the book (and space for some more), a drawing room on the first floor meant for the ancient Black's family tree, a kitchen with a small cupboard for Kreacher!
