Black panels with a raised barn-door pattern hide 20 cubic feet of storage behind a 46.5-in x 25-in x 37-in shell that clears most window sills. Its floor is rated to 661 lbs, the shelf to 33 lbs, the top to 166 lbs, and 860 lbs overall, so bags of soil can go low while lighter bottles sit on the adjustable shelf. That shelf moves through three positions at 6-in increments and measures 44-in x 11-in. The lift-up lid swings to 80 degrees for overhead loading, and together with the two front doors it locks in three places. Molded HDPE stands up to sun and drizzle without fading, wipes clean quickly, and keeps the assembled unit at 52 lbs, heavy enough to stay planted yet movable across a patio.
