The present invention relates to a variable greenhouse structure and a construction method therefor, wherein a roof can be opened or closed and the height of a greenhouse structure can be adjusted according to outdoor influences caused by changes in the season and weather, such as temperature and humidity, wind, snow, rain and the like, thereby providing optimal environments for the growth of animals and plants grown inside of the greenhouse structure. The present invention provides the variable greenhouse structure and the construction method therefor, wherein the variable greenhouse structure comprises: an inner panel and an outer panel capable of vertically moving a greenhouse structure which is formed by including a wall frame and a roof frame coupled to the upper part of the wall frame, wherein the inner and outer panels are spaced from each other at certain intervals in the ground such that the wall frame can be inserted into the ground a guide groove which is formed in a part in which the inner panel and the outer panel face each other, and which guides the vertical movement of the wall frame a cylinder support which is vertically provided on the upper part of the outer panel in which the guide groove is formed a roller guide which is coupled to one lateral side of the cylinder support in the longitudinal direction of the cylinder support and an elevation cylinder which is positioned on the other lateral side of the cylinder support, wherein the elevation cylinder is fixed by allowing the upper end thereof to be connected to the cylinder support.The variable greenhouse structure further comprises: an outer roller which is protruded from the outer side on a lower end of the wall frame, and which is coupled to a lower end of an axis of the elevation cylinder to move along the guide groove of the outer panel an inner roller which is protruded from the inner side on the lower end of the wall frame, and which is capable of moving along the guide groove of the inne
