18x20 Pergolas

We offer a wide selection of 18x20 pergola kits, including both free-standing and house-attached kits, those with a shade canopy on top and those made for a slatted wood roof, and some with smaller-sized posts & beams and others with larger ones. If none of these kits meet your needs, use our 30-second kit designer tool to create your ideal pergola.
