Two measurements and a few photos get it started. Measure the width of wall you want shaded, along where the awning will mount, and note anything that limits it: a corner, a downspout, a light or trim. Then decide the projection: how far out from the wall you want the shade to reach. Photograph the whole wall, the mounting area close up, and the patio from the side, and tell us what the wall is made of. We build to your width and projection.
