The invention discloses a habitable greenhouse. The habitable greenhouse comprises a greenhouse body and a living floor, wherein the living floor is arranged above the greenhouse body. The habitable greenhouse is characterized in that an LED lamp is arranged on a ceiling in the greenhouse body, a plurality of reflectors are installed on the outer side wall or the periphery of the greenhouse body, and an inclined angle formed by each reflector and the ground is adjustable. The habitable greenhouse integrates a living function and an office function, so that the planting area of the greenhouse is not occupied, and the land utilization rate is increased; and the solar energy is sufficiently utilized to illuminate plants, so that not only is the energy utilization rate increased, but also the growth of the plants and the yield of crops can be guaranteed. The LED lamp supplements the light to the plants, and the light is supplemented to the crops at daytime by virtue of secondary reflection, so that the solar utilization rate and the light action efficiency are further increased.
