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 16x16 ft Gabled Pergola Plan lands in the $5,450–$8,500 range for materials in Douglas Fir, while the 16x16 ft Modern Slatted Pergola Plan runs $4,875–$7,625 in Pressure-Treated Pine. The second plan is approximately 11% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Douglas Fir over Pressure-Treated Pine and the difference in cubic concrete volume between 4 and 4 footings.
Labor & difficulty
At ~24 hours, the 16x16 ft Gabled Pergola Plan is rated Beginner. The 16x16 ft Modern Slatted Pergola Plan takes ~12 hours and is rated Beginner. The labor delta is roughly 12 hours, or one extra working day on the 16x16 ft Gabled Pergola 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 256 sq ft vs 256 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 16x16 ft Gabled Pergola Plan needs a clear area of approximately 20×20 ft and the 16x16 ft Modern Slatted Pergola Plan needs 20×20 ft.
Material & durability
The 16x16 ft Gabled Pergola Plan is built from Douglas Fir, while the 16x16 ft Modern Slatted Pergola Plan calls for Pressure-Treated Pine. 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, 16x16 ft Modern Slatted Pergola 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.
