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 10x12 ft Open Air Screened Gazebo Plan lands in the $4,375–$6,850 range for materials in Douglas Fir, while the 3x4 ft Pergola Archway Arbor Plan runs $275–$450 in Black Locust. The second plan is approximately 1464% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Douglas Fir over Black Locust and the difference in cubic concrete volume between 6 and 2 footings.
Labor & difficulty
At ~15 hours, the 10x12 ft Open Air Screened Gazebo Plan is rated Beginner. The 3x4 ft Pergola Archway Arbor Plan takes ~33 hours and is rated Intermediate. The labor delta is roughly 18 hours, or one extra working day on the 3x4 ft Pergola Archway Arbor Plan. If you are newer to outdoor woodworking, the 10x12 ft Open Air Screened Gazebo Plan is the safer pick — it uses simpler joinery and fewer compound cuts.
Footprint & site fit
At 120 sq ft vs 12 sq ft, you are choosing between a generous patio cover and a focal-point garden structure. Allow at least 24 inches of clearance on every side for furniture and walking paths — that means the 10x12 ft Open Air Screened Gazebo Plan needs a clear area of approximately 14×16 ft and the 3x4 ft Pergola Archway Arbor Plan needs 7×8 ft.
Material & durability
The 10x12 ft Open Air Screened Gazebo Plan is built from Douglas Fir, while the 3x4 ft Pergola Archway Arbor Plan calls for Black Locust. 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, 3x4 ft Pergola Archway Arbor 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.
