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 6x8 ft Mid-Century Geometric Privacy Screen Trellis Plan lands in the $400–$625 range for materials in Pressure-Treated Pine, while the 6x6 ft Modern Black-Frame Privacy Screen Trellis Plan runs $575–$900 in Black Locust. The first plan is approximately 45% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Black Locust over Pressure-Treated Pine and the difference in cubic concrete volume between 3 and 3 footings.
Labor & difficulty
At ~40 hours, the 6x8 ft Mid-Century Geometric Privacy Screen Trellis Plan is rated Intermediate. The 6x6 ft Modern Black-Frame Privacy Screen Trellis Plan takes ~14 hours and is rated Beginner. The labor delta is roughly 26 hours, or one extra working day on the 6x8 ft Mid-Century Geometric Privacy Screen Trellis Plan. If you are newer to outdoor woodworking, the 6x6 ft Modern Black-Frame Privacy Screen Trellis Plan is the safer pick — it uses simpler joinery and fewer compound cuts.
Footprint & site fit
At 48 sq ft vs 36 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 6x8 ft Mid-Century Geometric Privacy Screen Trellis Plan needs a clear area of approximately 10×12 ft and the 6x6 ft Modern Black-Frame Privacy Screen Trellis Plan needs 10×10 ft.
Material & durability
The 6x8 ft Mid-Century Geometric Privacy Screen Trellis Plan is built from Pressure-Treated Pine, while the 6x6 ft Modern Black-Frame Privacy Screen Trellis 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, 6x6 ft Modern Black-Frame Privacy Screen Trellis 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.
