Common Questions
Frequently asked questions
- Do I need to buy a separate plan set for each size?
- No. The BWS-PG-01 download is one parametric plan set that covers all 7 sizes — 10×10, 10×12, 12×12, 10×14, 12×14, 10×16 and 12×16 — for a single price. Checkout and download are the same no matter which size you build.
- What is included in the download?
- A 13-page PDF construction document set: cover sheet and drawing index, foundation and post layout plan, framing plan, top slat plan with three shade-density options, exterior elevations, and post base / beam connection details, plus a lumber and hardware schedule and cut list.
- Can I choose how much shade the pergola gives?
- Yes. The top slat plan sheet gives you three spacing options — light (12" on center) for maximum sun, standard (6" on center) for balanced dappled shade, or dense (4" on center) for the most coverage.
- Is this a freestanding structure?
- Yes. The BWS-PG-01 is a freestanding, open-air pergola on its own posts and footings — it does not attach to a house wall.
- What foundation does it use?
- Post base options are detailed in the plan set. Foundation type, bearing capacity, frost depth and anchorage requirements are site-specific — verify them for your soil, climate and local building code before you build.
- Do I need a permit to build a pergola?
- Permit requirements for pergolas and other accessory structures vary by city and county, and often depend on size, height and proximity to property lines. Check with your local building department before you build — see our permit basics guide for what to ask.
