How to Make a Precast Concrete Bench and Planter

How to Make a Park Ave Concrete Bench and Planter | CHENG Concrete Exchange

The Park Avenue Planter and Bench is a versatile, multi-functional seating area that turns your balcony or patio into a streamlined garden getaway. Because the bench is split into three pieces, it is not permanent and can be moved around with relative ease. Using a few bright colors will make for a fun looking bench, perfect for the Spring and Summer get togethers. The deep planters give the plants’ roots room to grow, and a drain hole in the bottom ensures they won’t fill up with water when it rains.
