We chose not to DIY this, but I'm so pleased with the result. I don't have a picture of the entire patio, but this shows the new section we had added today. It almost doubles our usuable space, and we're going to create something of an outdoor kitchen over here to get the grill, etc. out of the way of the main part of the patio. The planters are lined up along the edge where the patio used to end.
I can't believe they got the whole job done in one day! It would have taken us six months to do it ourselves, LOL.
