PURPOSE: To provide a wall housed kitchen by which a living space can be used effectively and a selection of room arrangement can be enlarged.

CONSTITUTION: A wall housed kitchen 1 is provided with a water washing sink 11 which can change over between a state in which a lower part is supported rotatably by a pivot shaft 3 so that an upper part side jumps out forehand from a wall surface 2 and a state in which the upper part side is housed in a housing space 21 in the wall surface 2. On both sides of the water washing sink 11, a range stand 15 and a cooking stand 19 are mounted, which are folded and housed in the housing space 21 together with the water washing sink 11. The pivot shaft 3 works also as a water supply/discharge tube (a tube for passing water). By this constitution, as the wall housed kitchen can be drawn out of or housed in the housing space at need, limited living space can be utilized effectively. Further, the wall housed kitchen can also be mounted in a living room or a bed room. Thus, a room arrangement free from a conventional and stereotype idea can be adopted.
