Simple gorgeous wooden curtain wall with slats and tongue & groove cedar. Does the owner receive a lacquer wood repair plan? I will predict every 2 years that you will need to re-apply wood exposed to the weather. The large eaves of the Carlton project will help. I expect gray specked cedar in the south to the mountainside for three years without maintenance. I like this expression to see it pop up everywhere – but anyone in the Pacific Northwest can tell you that a clear finish is very easy to fail with cupping and graying out.
