Offcuts were used for the simple built-up trim applied to the bases and tops of the cedar-clad columns.
Clad support columns that have been stained to match the trim on the rest of the house look more substantial than bare 6x6 PT posts and do a better job of visually anchoring a tall deck to the ground.
Drop blocks were added to the cantilevered section of this deck to support tiered trim that will be used to finish the fascia.
Posts can usually be clad with standard 1x6 and 1x8 trim, but check post dimensions first. Often, at least one face of a 6x6 post measures more than 5 1/2 inches wide.
Wide cladding, such as 1x12 rim fascia, makes 6x6 posts look even more substantial, but blocking must be added to properly support the trim.
This deck is conventionally framed with 6x6 wood posts. The masonry columns are laid up around each post and tied to it with galvanized brick ties.
