12×20 Portable Greenhouse in Union Nebraska

Portable Greenhouse Project by Creative Backyards

Ashley and Andrew had plants that outgrew their space long before they had a place to put them. They needed room to actually work, not just survive another season.

Their 12×20 greenhouse near Union, Nebraska gives them that room. Built by Mid-America Structures, it features 8′ sidewalls that open up the vertical growing space most hobby greenhouses skip entirely. The 8mm double-wall polycarbonate panels on the roof and sidewalls pull in consistent light while holding heat through cooler Nebraska mornings. Workbenches run along both sides so there’s always a surface to pot, propagate, or just think. Creative Backyards worked with them across multiple visits to get the layout right before anything was ordered. Now they have a greenhouse that works the way they garden.
