Need a custom design?
If none of the ten is the structure you want, tell us what is: a span, a roof line, a pair of posts you have already set, a photograph of something you saw. Sierra designs it and prices it at no charge, the same way the ten below were designed.
What that covers is the design and the quote. Stamped engineering, permits and putting the structure up are quoted separately or arranged by you — they vary by county and by site, and nobody can promise them from a web page.
