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 12x16 ft Dutch Gable Pavilion Plan lands in the $13,950–$21,775 range for materials in Black Locust, while the 14x18 ft Dutch Gable Pavilion Plan runs $26,625–$41,600 in Composite (Trex / Azek). The first plan is approximately 91% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Composite (Trex / Azek) over Black Locust and the difference in cubic concrete volume between 6 and 6 footings.
Labor & difficulty
At ~20 hours, the 12x16 ft Dutch Gable Pavilion Plan is rated Beginner. The 14x18 ft Dutch Gable Pavilion Plan takes ~96 hours and is rated Advanced. The labor delta is roughly 76 hours, or one extra working day on the 14x18 ft Dutch Gable Pavilion 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 192 sq ft vs 252 sq ft, you are choosing between a generous patio cover and a full outdoor room. Allow at least 24 inches of clearance on every side for furniture and walking paths — that means the 12x16 ft Dutch Gable Pavilion Plan needs a clear area of approximately 16×20 ft and the 14x18 ft Dutch Gable Pavilion Plan needs 18×22 ft.
Material & durability
The 12x16 ft Dutch Gable Pavilion Plan is built from Black Locust, while the 14x18 ft Dutch Gable Pavilion 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, 12x16 ft Dutch Gable Pavilion 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.
