Open louvers on a white aluminum pergola throw precise diagonal shadow stripes across the dark gray siding of a modern home, framing an outdoor bar with a poured concrete countertop, bar stools, and a built-in grill visible to the right. The monochromatic white-on-white structure against the dark home exterior creates a sharp visual contrast — a Southern California attached pergola install that shows how the adjustable louvered roof integrates cleanly with contemporary architecture while delivering functional shade over an outdoor kitchen bar.
