I’m Amir — and cinderblock garden projects are one of those outdoor DIY categories where the material seems completely utilitarian and unglamorous until you see what creative gardeners actually build with it. Cinderblocks are extraordinarily strong completely weatherproof available almost everywhere for very little cost and can be stacked painted and combined into genuinely beautiful garden structures that would cost a fortune if built from any other material. We built a simple cinderblock raised garden bed last spring and a cinderblock bench in the seating area and both have become genuinely beloved features of our garden — the raised bed is incredibly productive and the bench with its colorful cushions has become the most used garden seating spot. These 20 cinderblock garden ideas cover everything from raised beds and beautiful bench designs to fire pits outdoor kitchens retaining walls and creative shelving projects.
