Playhouse is a small structure for children. The distinctive feature of the design is in its use of the "negative" spaces that are created by the bypass system of construction. The structure shares a similarity with log construction where beam-like elements (logs) are used to create walls by being stacked on top of one another. In this design, the stacking of beams perpendicularly to each other creates spaces that are part of the spatial design. The sizes of the spaces are determined by the sizes of the structural elements used. The structural elements of the Playhouse serve as play. They are intended to be climbed. Thus the Playhouse is not only a shelter for children but also a machine to be used in play.
There are two entrances to the Playhouse. The main entrance requires climbing over a wood seat slab. The "secret" entrance is from underneath the structure. Both entries serve to emphasize the magical crossing of the threshold that separates the inside space from the outside space.
