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 4x8 ft Farmhouse Gate Arbor Plan lands in the $400–$625 range for materials in Pressure-Treated Pine, while the 4x6 ft Trellis-Side Arbor Plan runs $425–$650 in Cypress. The first plan is approximately 5% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Cypress over Pressure-Treated Pine and the difference in cubic concrete volume between 2 and 2 footings.
Labor & difficulty
At ~22 hours, the 4x8 ft Farmhouse Gate Arbor Plan is rated Beginner. The 4x6 ft Trellis-Side Arbor Plan takes ~16 hours and is rated Beginner. The labor delta is roughly 6 hours, or one extra working day on the 4x8 ft Farmhouse Gate Arbor 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 32 sq ft vs 24 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 4x8 ft Farmhouse Gate Arbor Plan needs a clear area of approximately 8×12 ft and the 4x6 ft Trellis-Side Arbor Plan needs 8×10 ft.
Material & durability
The 4x8 ft Farmhouse Gate Arbor Plan is built from Pressure-Treated Pine, while the 4x6 ft Trellis-Side Arbor Plan 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, 4x8 ft Farmhouse Gate Arbor Plan covers more square footage. 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.
