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 6x6 ft Farmhouse Gate Arbor Plan lands in the $850–$1,350 range for materials in Black Locust, while the 3x4 ft Pergola Archway Arbor Plan runs $275–$450 in Black Locust. The second plan is approximately 207% 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 2 and 2 footings.
Labor & difficulty
At ~9 hours, the 6x6 ft Farmhouse Gate Arbor Plan is rated Beginner. The 3x4 ft Pergola Archway Arbor Plan takes ~33 hours and is rated Intermediate. The labor delta is roughly 24 hours, or one extra working day on the 3x4 ft Pergola Archway Arbor Plan. If you are newer to outdoor woodworking, the 6x6 ft Farmhouse Gate Arbor Plan is the safer pick — it uses simpler joinery and fewer compound cuts.
Footprint & site fit
At 36 sq ft vs 12 sq ft, you are choosing between a focal-point garden structure and a focal-point garden structure. Allow at least 24 inches of clearance on every side for furniture and walking paths — that means the 6x6 ft Farmhouse Gate Arbor Plan needs a clear area of approximately 10×10 ft and the 3x4 ft Pergola Archway Arbor Plan needs 7×8 ft.
Material & durability
The 6x6 ft Farmhouse Gate Arbor Plan is built from Black Locust, while the 3x4 ft Pergola Archway Arbor 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, 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.
