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 10x10 ft Farmhouse Pergola Plan runs $1,900–$2,975 in Pressure-Treated Pine. The first plan is approximately 3% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Pressure-Treated Pine over Black Locust and the difference in cubic concrete volume between 4 and 4 footings.
Labor & difficulty
At ~100 hours, the 10x10 ft 3-Point Triangular Shade Sail Frame Plan is rated Advanced. The 10x10 ft Farmhouse Pergola Plan takes ~98 hours and is rated Advanced. The labor delta is roughly 2 hours, or one extra working day on the 10x10 ft 3-Point Triangular Shade Sail Frame Plan. Both plans require the same skill level, so the deciding factor is footprint and aesthetics rather than your comfort with carpentry.
Footprint & site fit
At 100 sq ft vs 100 sq ft, you are choosing between a focal-point garden structure and a focal-point garden structure. 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 10x10 ft Farmhouse Pergola Plan needs 14×14 ft.
Material & durability
The 10x10 ft 3-Point Triangular Shade Sail Frame Plan is built from Black Locust, while the 10x10 ft Farmhouse Pergola Plan calls for Pressure-Treated Pine. 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, these two plans are close in cost and effort — your choice comes down to style and footprint. 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.
