Eye Level Living. Heritage pergolas use low-maintenance materials for long outdoor life. Fiberglass beams are hand-laid for a seamless beam end-to-end, eliminating stick-on plastic end caps. The cast-stone bases are glass-fiber reinforced concrete made to look like custom stonework. Standard Heritage pergolas measure 14 feet wide, 14 feet long, and 9 feet high, but can be expanded up to 14 by 20 feet. Four cast-stone base profiles are available. Optional purlin kits provide additional shade. 888.782.1760. www.eyelevelliving.com.
