A greenhouse having a single-glazed structure in at least two sections (10, 11), at least one (11) of the sections being supported for lateral movement relative to the other section (10) or sections, whereby the two sections (10, 11) alternatively may be arranged one inside the other to give an at least partially double-glazed greenhouse or laterally adjacent one another to give a single glazed greenhouse of larger area, the sections having end walls (19) such that in the alternative configurations the greenhouse remains enclosed on all sides. The larger area, single-glazed configuration is used in summer; the double glazed configuration in winter and spring. Preferably the movable section rolls on ground rails (15, 16) into and out of the fixed section (10).
