Japanese studio mA-style architects has completed a metal-clad house with a smaller wooden house inside (+ slideshow).
The playhouse-like structure has a gabled rooftop that just skims the uppermost ceiling of the two-storey residence in Makinohara, which itself is a rectilinear box.
Located at the centre of the house, the little structure contains living rooms on both levels, while bathrooms and a closet are also slotted inside it on the ground floor.
Openings in the walls and ceiling provide windows to the rooms beyond, which include a kitchen and dining room below and bedrooms above.
Here's a few extra details from the architects:
