The modular deck planter bench has been a very popular design with our customers. The planter boxes are 20" square and are 17" tall, so there's plenty of room for your favorite flowers or other plants. As called for by the plan, the benches are 36" long, but this is a dimension that is easily expanded or contracted. The plan comes with detailed instructions for building and cutting, a list of the materials you need, some photos, and measured drawings -- we're always an email away, too.
