We are happy to design, install and maintain your very own custom Zen Den — an enclosed cedar vegetable garden for you!

Black Rock Garden Structures’s mission is sustainability. We design, install and maintain custom cedar vegetable gardens, custom cedar planter boxes chicken coops, arbors, pergolas, window boxes, obelisks, trellises and backyard composting devices serving Fairfield and Westchester counties since 2019.

They provide a valuable service to residents while educating clients about the closed loop of sustainable living. From harvesting food to preparing meals and properly discarding of food residuals. 

Compost is then returned to go to vegetable gardens and or landscape.
