<p>A greenhouse (1) is described. It consists of an above-ground portion (3) comprising heat insulating glass panels (7) and an enterable pit portion (4) which is adapted to extend below ground surface (5). The greenhouse comprises a door (6). The heat insulating glass panels are mounted in heat insulating frame elements (8). The pit portion comprises substantially vertical heat insulating wall elements (9) being provided with a height that they extend at least to a frost-free level (10) below the ground surface (5). The different elements are connected by connectors (35) making it easy to erect the greenhouse. The floor (11) of the pit (4) is uninsulated and is arranged at said frost-free level (10) whereby the greenhouse is kept frost-proof during wintertime due to the use of earth heat.</p> |
