Designers Note: This 7x12 Cattle Panel Greenhouse was designed to bridge the gap between affordability and structural integrity. Four years after the original build, it remains the most productive square footage on my homestead. Drawing on 30 years of design and construction experience, I’ve refined these plans to ensure that even a solo builder can achieve professional results. These notes and the accompanying review highlight the long-term durability and the small adjustments that make this greenhouse a permanent, high-performance garden fixture.
