We built this same style deck ast year but things changed this year. The county had a pergola fall so we had to add a lot of straps and bracing. It was a pain but came out great in the end. We used trex transcends decking ropeswing color and the border was treehouse. The pergola was made out of wood and wrapped in pvc board. The stairs had a slight flar to them. Great job by jose and his son who completed this deck in 10 days even with the 3 extra inspections.
