With louvers held at a mid-position between open and closed, this cream aluminum pergola demonstrates exactly what adjustable means — the partially open blades cast a striking checkerboard light-and-shadow grid across the stucco wall, flagstone patio, and lawn beyond. Lantern-style post lights frame both sides of the structure, and a well-established backyard with raised planting beds and mature trees is visible through the open end of the pergola with adjustable louvers.
