Cedar Pergola
Classic cedar timber pergola with open rafters providing dappled shade. $3,000–$12,000 installed. Western red cedar resists rot naturally — no treatment needed for 15–20 years. Standard size: 12×14 ft with 6×6 posts and 2×8 rafters. Grows more beautiful as it silvers. The quintessential garden structure.
Aluminum Louvered Pergola
Motorized aluminum louvers that rotate 0–160 degrees for adjustable shade and rain protection. $8,000–$25,000 installed. Push-button control — open for full sun, close for full shade or rain shelter. Integrated LED lighting and gutter system. Brands: StruXure, Equinox, Azenco. The premium modern pergola.
Vinyl Pergola Kit
Maintenance-free vinyl (PVC) pergola assembled from a kit. $2,000–$6,000. Never needs painting, staining, or sealing. White or tan colors. Lighter weight than wood. Kit assembly: 1–2 day weekend project. Best for homeowners who want the look without any upkeep.
Steel Modern Pergola
Powder-coated steel or black iron pergola with clean, angular lines. $5,000–$15,000. 4×4 or round steel posts with flat-bar rafters. Matte black finish is the most popular. Sleek and minimal — pairs with modern architecture. Add climbing plants for contrast against the dark metal.
Retractable Canopy Pergola
Pergola frame with a retractable fabric canopy that slides on tracks. $4,000–$12,000. Open for sun, close for shade — manual or motorized. Sunbrella or Olefin waterproof fabric. The best of both worlds — open pergola aesthetics with on-demand shade. Extends outdoor season in hot climates.
Wisteria or Vine Pergola
Rustic pergola intentionally designed to be covered by climbing plants. $2,000–$8,000 for structure. Wisteria, grape vines, climbing roses, or jasmine. Heavy-duty construction — wisteria can weigh 1,000+ lbs when mature. Creates a living roof of flowers and foliage. Takes 2–5 years to fully cover. Worth the wait.
⛺ Gazebos & Pavilions
Classic Octagonal Gazebo
Traditional 8-sided gazebo with a shingled roof, railings, and bench seating. $5,000–$15,000 for kit or custom. 10–14 ft diameter. Screened or open sides. Cupola on top for ventilation and visual charm. The most recognizable garden structure — Victorian, traditional, and romantic.
Open Pavilion
Four-post open-roof structure with a solid shingled or metal roof. $8,000–$25,000. 12×16 ft or larger. No walls — fully open sides for airflow and views. Houses outdoor kitchen, dining, or lounge furniture. The most functional garden structure — full weather protection with outdoor feel.
Screened Gazebo
Gazebo with full insect screens on all sides for bug-free outdoor living. $6,000–$20,000. Screen panels with a screen door entry. Ceiling fan for air circulation. Perfect for areas with mosquitoes, gnats, or no-see-ums. Eat dinner outdoors without a single bug bite.
Pop-Up Gazebo (Hardtop)
Permanent metal-frame hardtop gazebo assembled from a kit. $1,000–$5,000. Polycarbonate or galvanized steel roof. Powder-coated aluminum frame. 10×12 or 12×14 ft. Curtain panels for privacy. Budget alternative to custom-built — looks good, installs in a day, lasts 10–15 years.
Japanese Tea House
Minimalist open-sided structure inspired by traditional Japanese tea ceremony architecture. $5,000–$20,000. Post-and-beam construction with a hip roof. Bamboo, cedar, or dark-stained wood. Shoji screen panels optional. Tatami-inspired floor platform. Meditative, serene, and architecturally distinctive.
🌹 Arbors & Arches
Garden Entry Arbor
Freestanding arbor marking the entrance to a garden area. $300–$2,000. Cedar, metal, or vinyl construction. 4–5 ft wide, 7–8 ft tall. Climbing roses, clematis, or trumpet vine trained over it. Creates a sense of arrival — you're leaving the regular yard and entering the garden.
Arbor with Gate
Arbor structure with an integrated garden gate below. $500–$3,000. Defines a boundary between garden zones or front/back yard. Lattice sides for climbing plants. Self-closing gate keeps pets and children in (or out). Functional beauty — the perfect combination.
Arbor Tunnel / Walkway
Series of connected arches forming a covered walkway through the garden. $2,000–$10,000. Metal or wood arches spaced 4–6 ft apart along a path. Train climbing plants (roses, wisteria, grape) over the entire tunnel. Walking through a flower tunnel is a peak garden experience. Takes 2–3 years to fully establish.
Arbor with Built-In Bench
Arbor structure with a built-in bench seat underneath. $500–$3,000. Combination shade, seating, and garden focal point in one structure. Climbing plants overhead for dappled shade. Place at the end of a path as a destination. The garden equivalent of a cozy reading nook.
Moon Gate Arbor
Circular opening framed in wood or metal, creating a dramatic garden portal. $1,000–$5,000. Round frame with climbing plants trailing around the circle. Frames the view beyond — whatever is visible through the circle becomes a framed landscape painting. Asian-inspired but works in any garden style.
🏠 Garden Buildings
Potting Shed
Small garden building dedicated to potting, seed starting, and garden tool storage. $2,000–$10,000. Workbench at comfortable height, shelving, hooks for tools, sink if plumbing available. Skylight or large window for natural light. The gardener's equivalent of a workshop — every serious gardener wants one.
Garden Office (She Shed / He Shed)
Insulated garden building converted into a home office or creative studio. $5,000–$25,000. Electricity, insulation, and internet connection. French doors or bifold doors for natural light. Separate from the house — the commute is 30 seconds across the garden. Work-from-home with garden views.
Greenhouse
Glass or polycarbonate structure for year-round plant growing. $500–$15,000. Lean-to against the house, freestanding Victorian, or modern aluminum frame. Extends the growing season by 2–4 months. Orchids, seed starting, tropical overwintering. The ultimate garden structure for plant enthusiasts.

Barrel sauna or custom-built sauna building in the garden. $3,000–$15,000. Barrel saunas are the most popular backyard format — $3,000–$8,000 installed. Electric or wood-fired. Cedar construction for heat and moisture resistance. Pair with a cold plunge tub for the full Scandinavian experience.
Garden Bar / Pub Shed
Shed converted into a backyard bar with counter, stools, lighting, and drinks storage. $3,000–$15,000. Exterior serving window with a fold-down bar counter. String lights, bar stools, mini fridge, kegerator. The ultimate entertaining structure — your own private pub 30 feet from the house.
Summer House
Open or enclosed garden room used for relaxation, reading, and entertaining. $5,000–$20,000. Large windows or open front with French doors. Furnished with comfortable seating, books, and soft lighting. Not insulated for winter — a three-season retreat. The English garden tradition of a dedicated garden room.
🗿 Architectural Features
Garden Folly / Ruin
Intentionally rustic or incomplete structure creating a romantic garden focal point. $2,000–$15,000. Crumbling stone columns, a partial wall, or a mock ruin. Overgrown with climbing plants and moss. Creates the illusion of an ancient landscape with history and mystery. The most dramatic garden feature you can build.
Obelisk or Garden Tower
Tall, tapered structure (6–10 ft) serving as a vertical focal point. $100–$1,000. Metal, wood, or stone construction. Climbing plants trained up the sides (clematis, sweet peas). Place at the end of a vista, center of a bed, or intersection of paths. Vertical accent in a horizontal landscape.
Garden Bridge
Arched or flat bridge spanning a stream, dry creek bed, or garden path. $500–$5,000. Cedar, composite, or stone construction. Functional over water features or decorative over dry creek beds. Japanese-style arched bridges are the most popular. Creates a transitional moment — crossing the bridge enters a new garden zone.
Covered Breezeway
Roofed walkway connecting two areas of the garden or house to garden structure. $3,000–$15,000. Posts with a pitched roof, open sides. Climbing plants on the posts. Provides rain protection while walking between the house and a garden building. Architectural connection that makes the garden feel integrated with the home.
Bell Tower / Clock Tower
Small tower structure housing a garden bell or clock. $1,000–$8,000. Copper bell or weather-resistant outdoor clock. Stone, brick, or timber construction. Heights of 8–15 ft. Unique focal point that adds character and whimsy. Ring the bell to call the family to dinner.
🔨 Budget & DIY Structures
Cattle Panel Arch ($50–$150)
16 ft cattle panel (livestock fence panel) bent into an arch and staked into the ground. Instant garden arch for $50. Plant climbing beans, cucumbers, or flowers. Two panels side by side create a tunnel. The cheapest and fastest garden structure — 30 minutes to install.
PVC Pipe Pergola ($100–$300)
Pergola frame built from 2 in PVC pipe and fittings. Lightweight, inexpensive, and easy to build. Paint with exterior paint to hide the plastic look. Train vines over it for a covered garden structure. Not as durable as wood but costs 10% of a cedar pergola.
Pallet Potting Bench ($0–$50)
Two pallets standing upright with a plank shelf between them creating a potting station. Free materials if you source pallets. Add hooks for tools, shelves for pots, and a work surface. Sand and stain for a finished look. The easiest garden structure to build — no cutting required.
Shade Sail Triangle ($100–$400)
Triangular shade sail tensioned between three points (posts, trees, house). $100–$400 for the sail plus hardware. UV-protective fabric in neutral or bold colors. 5-minute seasonal installation and removal. Modern, clean shade solution without permanent construction.
Bent Willow Arbor ($50–$200)
Garden arbor made from fresh willow branches bent and woven into an arch. $50–$200 for materials (or free if you harvest your own willow). Rustic, organic, fairy-tale aesthetic. Willow can root and grow — creating a living arbor. Lasts 3–5 years before needing replacement. Enchanting and unique.

❓ Frequently Asked Questions
Do I need a permit for a garden structure?
Pergolas, gazebos, and pavilions: most jurisdictions require permits for permanent structures over a certain size (often 120–200 sq ft). Arbors and arches under 10 ft tall: usually no permit. Garden sheds: permit thresholds vary — often 100–200 sq ft without a permit. Any structure with electrical or plumbing: permit required. Any structure attached to the house: permit required. Always check local codes before building.
What's the best wood for garden structures?
Western red cedar: naturally rot-resistant, beautiful, affordable ($8–$15/board ft). Redwood: premium, rot-resistant, expensive ($15–$25/board ft). Pressure-treated pine: cheapest ($3–$6/board ft) but needs staining and has a green tint. Ipe (Brazilian hardwood): incredibly durable ($15–$25/board ft) but heavy and hard to work. For most homeowners, cedar is the best balance of beauty, durability, and cost.
How much does a pergola cost?
DIY kit pergola (vinyl/wood): $1,000–$4,000. Custom cedar pergola (contractor-built): $3,000–$12,000. Aluminum louvered pergola: $8,000–$25,000. Factors: size (12×12 costs less than 14×20), materials, freestanding vs attached, and labor market. A standard 12×14 cedar pergola typically runs $5,000–$8,000 installed by a contractor.
What's the difference between a pergola, gazebo, and pavilion?
Pergola: open-roof structure with rafters that provide partial shade (no solid roof). Gazebo: enclosed structure with a solid roof, usually octagonal or round, with railings. Pavilion: open-sided structure with a solid roof — like a gazebo without walls. Arbor: small, arch-shaped structure typically at a garden entrance. Each serves a different function and aesthetic.
Can I build a garden structure on a deck?
Yes, but the deck must support the additional weight. A cedar pergola adds 500–1,500 lbs of concentrated load at the post locations. Bolt post bases to the deck framing, not just the deck boards. Ideally, posts should go through the deck to independent footings below. Consult with a structural engineer for large structures on elevated decks.
What climbing plants grow fastest on garden structures?
Fastest: Trumpet vine (15–20 ft/year), morning glory annual (10–15 ft/season), hyacinth bean vine (10–15 ft/season). Fast: Clematis (6–10 ft/year), climbing roses (4–8 ft/year), wisteria (6–10 ft/year but takes 3–5 years to bloom). Moderate: Climbing hydrangea (3–5 ft/year, slow start but stunning). For quick coverage, plant an annual vine (morning glory) the first year while a perennial (clematis) establishes.
