If you have narrowed your shortlist to two specific designs, this is exactly the kind of decision where a side-by-side spec view saves a weekend of second-guessing. Both plans below are complete, code-aware DIY builds, but they differ on the things that matter for a backyard project — total cost, raw labor hours, footprint, and the wood species on the cut list.

Cost & budget
The 16x20 ft A-Frame Pavilion Plan lands in the $11,950–$18,700 range for materials in Pressure-Treated Pine, while the 10x8 ft Hot Tub Surround Privacy Screen Trellis Plan runs $925–$1,450 in Cypress. The second plan is approximately 1200% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Pressure-Treated Pine over Cypress and the difference in cubic concrete volume between 6 and 4 footings.
Labor & difficulty
At ~141 hours, the 16x20 ft A-Frame Pavilion Plan is rated Advanced. The 10x8 ft Hot Tub Surround Privacy Screen Trellis Plan takes ~42 hours and is rated Intermediate. The labor delta is roughly 99 hours, or one extra working day on the 16x20 ft A-Frame Pavilion Plan. If you are newer to outdoor woodworking, the 10x8 ft Hot Tub Surround Privacy Screen Trellis Plan is the safer pick — it uses simpler joinery and fewer compound cuts.
Footprint & site fit
At 320 sq ft vs 80 sq ft, you are choosing between a full outdoor room and a focal-point garden structure. Allow at least 24 inches of clearance on every side for furniture and walking paths — that means the 16x20 ft A-Frame Pavilion Plan needs a clear area of approximately 20×24 ft and the 10x8 ft Hot Tub Surround Privacy Screen Trellis Plan needs 14×12 ft.
Material & durability
The 16x20 ft A-Frame Pavilion Plan is built from Pressure-Treated Pine, while the 10x8 ft Hot Tub Surround Privacy Screen Trellis Plan calls for Cypress. The species choice drives the cost delta and the maintenance schedule. Pressure-treated southern yellow pine is the cheapest and most rot-tolerant for in-ground posts; western red cedar is the DIY favorite for visible parts; redwood and white oak are heritage choices that command a premium.
Verdict
For a builder weighing these two specifically, 10x8 ft Hot Tub Surround Privacy Screen Trellis Plan is the clear budget pick. If both fit your budget and yard, default to the design whose style language matches the rest of your house — a Craftsman bungalow looks awkward beside a modern slatted pergola, and vice versa.
