A laundry treatment apparatus comprising a washing apparatus (1, 3) for washing laundry and a drying apparatus for drying laundry, wherein the washing apparatus (1, 3) comprises: a first cabinet; a first drawer drawably disposed in the first cabinet; a first receiver disposed in the first drawer so as to contain laundry therein, wherein the first receiver includes a first tub disposed in the first drawer so as to contain washing water, a first drum rotatably disposed in the first tub so as to contain laundry, and a first introduction port provided in the first tub so as to be parallel to a bottom surface of the first cabinet; a first drum-rotating shaft extending through the first tub, the first drum-rotating shaft being connected to the first drum so as to be perpendicular to the bottom surface of the first cabinet; a first drum driving unit for rotating the first drum-rotating shaft; a first controller for controlling the first drum driving unit; a second cabinet disposed under the first cabinet so as to support the first cabinet; a second drawer drawably disposed in the second cabinet; a second receiver disposed in the second drawer so as to contain laundry, wherein the second receiver includes a second tub disposed in the second drawer so as to contain washing water, a second drum rotatably disposed in the second tub so as to contain laundry, and a second introduction port provided in an upper wall of the second tub so as to be parallel to a bottom surface of the second cabinet; a second drum-rotating shaft extending through the second tub, the second drum-rotating shaft being connected to the second drum so as to be perpendicular to the bottom surface of the second cabinet; a second drum driving unit for rotating the second drum-rotating shaft; a second controller for controlling the second drum driving unit, and wherein the drying apparatus comprises: a cabinet disposed on a lateral side of the washing apparatus (1, 3), the cabinet having an introduction port formed in a front wall thereof for introduction and discharge of laundry; a receiver disposed in the cabinet so as to define a space for receiving laundry introduced through the introduction port; and a drying unit for supplying air to the receiver to dry laundry, wherein, when the first drum-rotating shaft and the second drum-rotating shaft are rotated concurrently, at least one of the first and second controllers (C1, C2) controls the first drum driving unit and the second drum driving unit so as to prevent the first drum-rotating shaft and the second drum-rotating shaft from rotating in the same direction. a first cabinet; a first drawer drawably disposed in the first cabinet; a first receiver disposed in the first drawer so as to contain laundry therein, wherein the first receiver includes a first tub disposed in the first drawer so as to contain washing water, a first drum rotatably disposed in the first tub so as to contain laundry, and a first introduction port provided in the first tub so as to be parallel to a bottom surface of the first cabinet;
