Artisan quality and made to last a lifetime. There are many variations of this style but the same system. This is 1” cedar all pre sealed before assembly. It’s all tongue & grooved then assembled. It is also cladded on the inside with 1x6 fence boards. It is a very concise system. They are awesome for small trees given it’s bottomless and the sides are 4” thick. Blueskin is used on all pressure treated wood that is below grade and would have soil up against it. As l mentioned they are created to last till kingdom come. Drop me a line for a quote of the many variations.
