This is a little landscape job we just recently did in Chapel Hill, NC. Lots of purple, makes a great accent and warms up the front yard.
These raised garden beds were constructed with Cox re dried pressure treated lumber which comes ready to paint. Normal treated lumber you get at the big box store you need to let it dry 4-6 months before painting it. Because of the high moisture content in normal treated lumber painting it would lock in the moisture and cause it to rot from the inside out.
The 12 foot long purple bench with an Italian accent tile routed into it.
This shows the details of how the back of the bench was made, used 1/2 inch galvanized carriage bolts and leaned the back rest at 15 degrees. The 4 posts are 4 x 6s planted in the ground 2 foot with concrete, this bench is very solid.
