PROBLEM TO BE SOLVED: To provide a vinyl house easy to open and close and having a good ventilation efficiency in the interior of the house. SOLUTION: This vinyl house has a roof frame constituted of a ridgepole 6 and left and right gutters 9 and 9 parallel thereto and installed so as to freely lift or lower the left or right gutter 9 supported by the ridgepole 6 as a supporting point, and two ply of light-shielding synthetic resin sheets 5 stretched from one gutter 9 to the other gutter 9 over the ridgepole 6, sealed at the perimeter edges, filled by air between the sheets to smooth a flow of the air to be discharged from the interior of the house and heighten a ventilation efficiency by parting the left and right gutter 9 apart from the roof frame at the ridgepole part when the roof is opened. |
