I like the stone base. We could use brick to match house. Traditional structures like this new pergola–porch can be built from modern materials that are impervious to moisture and insects (Kleer Lumber components from Tapco).
I like this open layout. Like the pergola over the table, grill, and bar. Don't like the plastic on top and wouldn't do ceiling fans or lanterns. White Christmas lights would be prettier Architectural Landscape Design
If your deck or patio is partially covered, drape lengths of fabric or canvas between the joists to create shade. Space out the pieces of fabric for a more transparent look, and add lights to illuminate the space at night.
