This enclosed garden and greenhouse provides ample outdoor space for growing vegetables, flowers, and herbs; and climate controlled interior space for seeding plants and growing orchids in the cooler months. Sometimes referred to as a pit greenhouse, the floor of the glass enclosure is 4 feet below grade and uses the earth as added insulation.To reduce cost, the architect selected a stock greenhouse system provided by a national greenhouse company and requested a variance from its standard gabled roof profile: a free-standing shed, still employing the company’s standard details and stock materials.
