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 10x10 ft 3-Point Triangular Shade Sail Frame Plan lands in the $1,850–$2,875 range for materials in Black Locust, while the 12x16 ft Dutch Gable Pavilion Plan runs $13,950–$21,775 in Black Locust. The first plan is approximately 658% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Black Locust over Black Locust and the difference in cubic concrete volume between 4 and 6 footings.
Labor & difficulty
At ~100 hours, the 10x10 ft 3-Point Triangular Shade Sail Frame Plan is rated Advanced. The 12x16 ft Dutch Gable Pavilion Plan takes ~20 hours and is rated Beginner. The labor delta is roughly 80 hours, or one extra working day on the 10x10 ft 3-Point Triangular Shade Sail Frame Plan. If you are newer to outdoor woodworking, the 12x16 ft Dutch Gable Pavilion Plan is the safer pick — it uses simpler joinery and fewer compound cuts.
Footprint & site fit
At 100 sq ft vs 192 sq ft, you are choosing between a focal-point garden structure and a generous patio cover. Allow at least 24 inches of clearance on every side for furniture and walking paths — that means the 10x10 ft 3-Point Triangular Shade Sail Frame Plan needs a clear area of approximately 14×14 ft and the 12x16 ft Dutch Gable Pavilion Plan needs 16×20 ft.
Material & durability
The 10x10 ft 3-Point Triangular Shade Sail Frame Plan is built from Black Locust, while the 12x16 ft Dutch Gable Pavilion Plan calls for Black Locust. Both plans share the same species, so you can buy from a single lumber order if you build them in sequence — a common move for homeowners adding both a primary structure and a complementary screen or arbor.
Verdict
For a builder weighing these two specifically, 10x10 ft 3-Point Triangular Shade Sail Frame 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.
