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 12x12 ft Octagonal Victorian Gazebo Plan lands in the $8,575–$13,400 range for materials in White Oak, while the 12x12 ft Pagoda-Style Gazebo Plan (Mahogany) runs $11,625–$18,150 in Mahogany. The first plan is approximately 35% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Mahogany over White Oak and the difference in cubic concrete volume between 6 and 6 footings.
Labor & difficulty
At ~58 hours, the 12x12 ft Octagonal Victorian Gazebo Plan is rated Advanced. The 12x12 ft Pagoda-Style Gazebo Plan (Mahogany) takes ~147 hours and is rated Advanced. The labor delta is roughly 89 hours, or one extra working day on the 12x12 ft Pagoda-Style Gazebo Plan (Mahogany). 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 144 sq ft vs 144 sq ft, you are choosing between a generous patio cover and a generous patio cover. Allow at least 24 inches of clearance on every side for furniture and walking paths — that means the 12x12 ft Octagonal Victorian Gazebo Plan needs a clear area of approximately 16×16 ft and the 12x12 ft Pagoda-Style Gazebo Plan (Mahogany) needs 16×16 ft.
Material & durability
The 12x12 ft Octagonal Victorian Gazebo Plan is built from White Oak, while the 12x12 ft Pagoda-Style Gazebo Plan (Mahogany) calls for Mahogany. 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, 12x12 ft Octagonal Victorian Gazebo 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.
