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 12x12 ft Asian-Inspired Pergola Plan lands in the $2,750–$4,275 range for materials in Pressure-Treated Pine, while the 10x14 ft Mission Pergola Plan runs $7,525–$11,750 in Composite (Trex / Azek). The first plan is approximately 174% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Composite (Trex / Azek) over Pressure-Treated Pine and the difference in cubic concrete volume between 4 and 4 footings.
Labor & difficulty
At ~25 hours, the 12x12 ft Asian-Inspired Pergola Plan is rated Intermediate. The 10x14 ft Mission Pergola Plan takes ~11 hours and is rated Beginner. The labor delta is roughly 14 hours, or one extra working day on the 12x12 ft Asian-Inspired Pergola Plan. If you are newer to outdoor woodworking, the 10x14 ft Mission Pergola Plan is the safer pick — it uses simpler joinery and fewer compound cuts.
Footprint & site fit
At 144 sq ft vs 140 sq ft, you are choosing between a generous patio cover and a generous patio cover. Allow at least 24 inches of clearance on every side for furniture and walking paths — that means the 12x12 ft Asian-Inspired Pergola Plan needs a clear area of approximately 16×16 ft and the 10x14 ft Mission Pergola Plan needs 14×18 ft.
Material & durability
The 12x12 ft Asian-Inspired Pergola Plan is built from Pressure-Treated Pine, while the 10x14 ft Mission Pergola Plan calls for Composite (Trex / Azek). 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, 12x12 ft Asian-Inspired Pergola 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.
