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 Hot Tub Pavilion Plan lands in the $26,625–$41,600 range for materials in Composite (Trex / Azek), while the 14x18 ft Hot Tub Pavilion Plan (Cypress) runs $13,300–$20,775 in Cypress. The second plan is approximately 100% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Composite (Trex / Azek) over Cypress and the difference in cubic concrete volume between 6 and 6 footings.
Labor & difficulty
At ~102 hours, the 14x18 ft Hot Tub Pavilion Plan is rated Advanced. The 14x18 ft Hot Tub Pavilion Plan (Cypress) takes ~20 hours and is rated Beginner. The labor delta is roughly 82 hours, or one extra working day on the 14x18 ft Hot Tub Pavilion Plan. If you are newer to outdoor woodworking, the 14x18 ft Hot Tub Pavilion Plan (Cypress) is the safer pick — it uses simpler joinery and fewer compound cuts.
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 Hot Tub Pavilion Plan needs a clear area of approximately 18×22 ft and the 14x18 ft Hot Tub Pavilion Plan (Cypress) needs 18×22 ft.
Material & durability
The 14x18 ft Hot Tub Pavilion Plan is built from Composite (Trex / Azek), while the 14x18 ft Hot Tub Pavilion Plan (Cypress) calls for Cypress. 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, 14x18 ft Hot Tub Pavilion Plan (Cypress) 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.
