{"product_id":"greenhouse-coldframe-plan","title":"Greenhouse-Coldframe","description":"\u003cp\u003eOne set of panels, two buildings — that's the trick of this 1962 USDA \/ University of Maryland plan (an Oregon design). Eight 2×2-framed wall panels, a hinged top and a vent cover, all skinned in plastic film. The four upper panels and the top make a low coldframe with a sloped, vented lid for starting seedlings. When the plants need headroom, lift that whole unit onto the four matching lower panels and drop twelve 3\/8\" carriage bolts through the doubled plates: it becomes a 7'-8\" × 5'-3\" walk-in greenhouse, 7'-8\" tall at the front and 5'-7\" at the rear, with a 6'-0\" two-leaf door in the right end and the hinged vent in the top.\u003c\/p\u003e\u003ch3\u003eAt a glance\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 7'-8\" × 5'-3\" footprint, 7'-8\" tall at the front (234 × 160 × 234 cm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSkill:\u003c\/strong\u003e Beginner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuild time:\u003c\/strong\u003e 1 weekend\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterials:\u003c\/strong\u003e approx.
