A pine cone provided the formal idea for this design. The concept foresees that the pine cone-shaped treehouse is penetrated by a large coniferous tree and is borne by it without additional supports. Depending on the height and size of the tree, the treehouse may be fitted with a second, mid-level terrace. Access is via a spiral staircase which ends in a floor hatch on the underside of the treehouse. The façade is clad in cedar shingles and fitted with metal-framed windows and doors. Inside, there are two levels with sleeping quarters, a small toilet and the living room with a cooking area.
