Not really a greenhouse but a home for plants. The roof is "zinc transparente" (as much as I hate that name). North wall is regular zinc roofing. The south and west sides have rabbit wire (called dos por dos here) for the bottom three feet. The footings are piedra cantera. It is raised (and covered) to keep it from turning into a swamp during the rainy season.
The wind is almost always from the northeast. Some sort of plastic (Ana's project) will get added to the chain link fence on the east side. Overall size is about 3 by 9 meters.
