A shelving unit displaying children's clothes doubles up as a plywood playhouse with a sliding staircase, swinging doors and removable furniture.

The playhouse occupies a children's clothes shop in Paris, designed by French studio Mut Architecture and architect Benjamin Mahon.

The set of steps slide out to allow shop-workers to reach the highest shelves, while a hollow box on wheels rolls away to provide an island table.

Other interiors that integrate children's play areas include a perforated bedroom wall that can be used as a ladder and a bed with a play den below.

The following short description is from the architects:

In collaboration with Benjamin Mahon, Mut architecture has completed a children's store in the 16th arrondissement of Paris.

The main concept for the store was to construct a large doll house within the store, a house you can pull drawers out of, swing doors from, ‪a doll house that lends itself to the imagination of children‬.

Ladders on wheels are embedded in the structure of the house, and a box is set within the house and can be removed to be used as a central island within the shop, to expose products.

From the street the giant house seems to be overwhelming the volume of the 16 meter square shop.

We used poplar plywood for the interior of the store with white stratification and mirrors to accent the fresh feel of the wood surfaces.
