Inside, there are four large steps, which serve as both seating areas and storage. One of the steps opens to form a double bed by manipulating the lid using a hinge mechanism. The retreat is heated with a small, simple wood stove. The multipurpose steps lead up to a large window at the top of the house so that the occupant is literally standing atop the boulder when looking through it. The steps are a very nice touch, since the occupant can use them to sit, sleep, or lounge as needed, while they also offset the sloping shape of the house.
