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 12x16 ft Hot Tub Pavilion Plan runs $13,950–$21,775 in Black Locust. The second plan is approximately 0% 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 6 and 6 footings.
Labor & difficulty
At ~20 hours, the 12x16 ft Dutch Gable Pavilion Plan is rated Beginner. The 12x16 ft Hot Tub Pavilion Plan takes ~138 hours and is rated Advanced. The labor delta is roughly 118 hours, or one extra working day on the 12x16 ft Hot Tub 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 192 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 12x16 ft Dutch Gable Pavilion Plan needs a clear area of approximately 16×20 ft and the 12x16 ft Hot Tub Pavilion Plan needs 16×20 ft.
Material & durability
The 12x16 ft Dutch Gable Pavilion Plan is built from Black Locust, while the 12x16 ft Hot Tub 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, 12x16 ft Dutch Gable Pavilion Plan is the faster build. 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.
