Lisieux is an old provincial French town. From other views I have seen of it, this low house is an exception - much of the rest of the town was built a story or two higher.
Despite its moderate height, this was an expensive building, with a great deal of elegant stone carving. Notice also that the windows are of very small panes set in lead. This is an old and very beautiful technique.
Notice that the upper story is nearly as large as the ground floor - the dormers actually come right out to main face of the building, and not much room is lost to the roof, which is steep and intersects the wall well above the level of the floor. It is not out of the question that there is even a small third floor, with dormers out the back.
Notice also that its neighbor is three stories high, a fairly typical value for this town.
