Pergolas & Outdoor Structures

Pergolas & Outdoor Structures in Los Angeles

A pergola, arbor, or covered outdoor structure is one of the highest-impact additions you can make to a Southern California property. Done well, it carves the backyard into rooms, throws useful shade across a patio, and brings the architectural language of the house out into the landscape. Done with cheap pressure-treated 4x4s and hardware-store lumber, it sags within a year and warps within three. The wood matters. At House of Hardwood, we supply the structural and decorative lumber for pergolas, arbors, trellises, ramadas, and other outdoor structures across Los Angeles. Learn more about the best hardwood for pergolas in Southern California before you choose your materials.

Important to know up front: We supply materials only. We do not build, design, install, or engineer pergolas or outdoor structures. The lumber, posts, beams, rafters, and decorative components for outdoor projects come from us; the build is handled by your contractor or licensed builder.

We have been operating out of our Wellesley Avenue yard since 1947. Bring us your structural plans, materials list, or a sketch with rough dimensions, and our team will work through termite-resistant hardwood species, sizing, and quantities with you.

What We Supply

Our outdoor structure work focuses on the lumber components your contractor needs:

• Structural posts in 4×4, 6×6, 8×8, and larger dimensions
• Load-bearing beams in 4×10, 4×12, 6×10, 6×12, and oversized custom dimensions
• Rafters and cross-beams in 2×6, 2×8, 2×10, and 2×12
• Top slats, lattice, and shade components in standard or custom widths
• Knee braces, corbels, and decorative supports
• Custom-milled rafter tail end cuts and decorative profiles
• Privacy screen and trellis components
• Fascia, soffit, and trim for pavilion-style covered structures

If your contractor sends us a materials takeoff list, we can quote the full lumber package.

Common Outdoor Structures

Different structures call for different lumber. The most common builds we supply for:

• Pergolas - The most-requested outdoor structure in Southern California. Open-roof or partially-shaded with slat tops or louvered lattice. Built primarily in Douglas fir, cedar, redwood, or ipe.
• Arbors - Smaller entry structures, garden archways, and gateway pieces. Often built in cedar, redwood, or Spanish cedar.
• Trellises - Climbing plant supports, privacy screens, and decorative wall-mounted structures. Cedar and Spanish cedar are common.
• Ramadas - Spanish and Southwest-style covered structures with solid roofs. Built in heavier timber, often Douglas fir or cedar.
• Outdoor pavilions and patio covers - Larger covered structures with shingled, tile, or solid roofing. Heavy timber framing in Douglas fir or premium hardwood.
• Gazebos - Freestanding garden structures, often hexagonal or octagonal. Cedar, redwood, or Douglas fir.
• Privacy screens and outdoor walls - Vertical slat assemblies, lattice panels, and decorative privacy structures. Cedar, Spanish cedar, or ipe decking lumber.

Species We Recommend

Outdoor structural wood needs to handle UV, rain, sprinklers, and seasonal humidity swings without rotting, twisting, or splitting. A few species we keep moving through the yard for this work:

• Old Growth Douglas Fir - The dominant choice for pergola framing. Tight vertical grain, structural strength, warm amber color, and excellent stain acceptance. Holds up beautifully when finished and maintained.
• Western Red Cedar (Vertical Grain) - Naturally rot-resistant, lightweight, and stable. Common for slat tops, trellises, smaller structures, and any build where weight matters.
• Clear A Redwood - The classic California choice. Naturally rot-resistant, warm reddish tones, and a strong fit for traditional and ranch-style properties.
• Ipe - The premium choice for high-end builds where decades of low-maintenance service are the goal. Extremely dense and naturally durable, but heavy and harder to work with.
• Mahogany and Sapele - For decorative components, gates, screens, and architectural feature pieces. See how Sapele and Mahogany compare for outdoor projects.
• Spanish Cedar - Aromatic, naturally insect-repellent, and a strong option for accent components and smaller structures.

If your project needs a species we don’t have on the rack, we can usually source it on a short turnaround.

Structural Components and Decorative Detail

The look of a pergola often comes down to the small choices: rafter tail profiles, post caps, corbel detailing, and the proportion of structural members to the overall scale. We mill:

• Custom rafter tail end cuts in classical, craftsman, or modern profiles
• Decorative chamfered post tops and bottoms
• Knee braces with curved or angled detail
• Oversized timber beams beyond standard yard dimensions
• Tongue and groove ceiling boards for covered structures
• Custom-width slat tops and lattice components

Send us a profile drawing, a reference photo, or a sample of the detail you want, and we will mill to match. For inspiration on how grain direction and cut affect the finished look of structural details, see our guide on end grain vs edge grain when buying hardwood boards.

A Note on Engineering, Measurement, and Installation

We supply lumber. We do not engineer outdoor structures, calculate beam spans, specify post depths, design footings, or handle permits. Pergolas and patio covers in Los Angeles often require permits and structural approval from the local building department, particularly for attached structures and any build over 120 square feet.

Your contractor, structural engineer, or architect is responsible for:

• Engineering and structural design
• Beam span calculations and post sizing
• Foundation and footing design
• Permit applications and code compliance
• Field measurement and dimensional layout
• Installation and assembly

We provide the materials your team specifies. If your contractor needs help understanding what species and dimensions will deliver the look they are after, our team can talk that through. We cannot substitute for an engineered structural design.

Maintenance and Aging

Outdoor lumber goes one of two ways: maintained with oil to hold its color, or left unfinished to weather to a silver-gray patina. Both are valid; the choice depends on the look you want and the maintenance commitment you can keep up with.

For maintained finishes, penetrating oils like Penofin, Messmer’s, and Cutek hold color in LA sun for one to two years before reapplication. For let-it-gray approaches, no maintenance is needed beyond occasional cleaning. The wood underneath is unchanged. If you’re weighing species options for a teak or ipe outdoor deck in LA, finish behavior is one of the key differences to factor in.

Sustainability Options

For projects with green building requirements or client sustainability standards, we carry FSC certified stock in select species and can source additional certified material to order. Certified lumber mills exactly like our conventional stock, with chain of custody documented for your file.

Sizing and Lead Times

Standard structural lumber in common dimensions ships in one to two weeks. Oversized beams, custom rafter tail profiles, and special-order species typically take three to five weeks. Large multi-structure landscape projects with significant material volumes take longer. We give you an honest schedule up front so you can coordinate with your contractor.

Who We Supply

We work with landscape contractors, custom home builders, remodel contractors, structural carpenters, architects, landscape designers, and homeowners running their own outdoor projects through a licensed builder. We have supplied pergola and outdoor structure lumber for hillside estates, beach houses, restaurant patios, hotel courtyards, and residential backyards across Los Angeles.
