The invention relates to a greenhouse-glasshouse structure which is a system for plant growing in a protected space, made of bent metal pipes arranged in the shape of a tunnel extended at its ends by two technical installation rooms, for producing hot-cold ambient, fans and draught chimneys for producing and discharging air streams, the entire structure being covered with transparent foil. According to the invention, the structure consists of bent metal pipes (1) driven into the soil, fixed on the ridge and sidewise with some metal conduits (15) wherethrough hot water circulates for melting the snow accumulated on top of the building, the resulting water being collected by a trough placed on the soil along the structure length and stored in some polyethylene containers (12) by using a pump with absorption from a collector and subsequently used for plant irrigation, it has a ceiling (2) made of non-woven polyethylene cloth located at 1/3 of the structure height from its ridge, and, in the vertical plane, a wal
