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 14x18 ft Dutch Gable Pavilion Plan lands in the $26,625–$41,600 range for materials in Composite (Trex / Azek), while the 14x18 ft Hot Tub Pavilion Plan runs $26,625–$41,600 in Composite (Trex / Azek). The second plan is approximately 0% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Composite (Trex / Azek) over Composite (Trex / Azek) and the difference in cubic concrete volume between 6 and 6 footings.
Labor & difficulty
At ~96 hours, the 14x18 ft Dutch Gable Pavilion Plan is rated Advanced. The 14x18 ft Hot Tub Pavilion Plan takes ~102 hours and is rated Advanced. The labor delta is roughly 6 hours, or one extra working day on the 14x18 ft Hot Tub Pavilion 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 252 sq ft vs 252 sq ft, you are choosing between a full outdoor room and a full outdoor room. Allow at least 24 inches of clearance on every side for furniture and walking paths — that means the 14x18 ft Dutch Gable Pavilion Plan needs a clear area of approximately 18×22 ft and the 14x18 ft Hot Tub Pavilion Plan needs 18×22 ft.
Material & durability
The 14x18 ft Dutch Gable Pavilion Plan is built from Composite (Trex / Azek), while the 14x18 ft Hot Tub Pavilion Plan calls for Composite (Trex / Azek). 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, 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.
