A timber frame pergola is an open-roof outdoor structure built with large posts, beams, rafters, and shade bars. It defines an outdoor living space, adds architectural character, and provides filtered shade while keeping the area open to light, air, and the surrounding landscape.
What makes a timber frame pergola different from a pergola built using more conventional carpentry is the way the structure is proportioned, joined, and finished. Timber framing uses larger structural members, traditional joinery details, and a more substantial construction method than pergolas built primarily from smaller dimensional lumber, nails, screws, or exposed brackets.
The main difference is the roof. A pergola has an open frame with rafters and shade bars, so it provides partial shade, airflow, and a more open connection to the outdoors. A pavilion has a solid pitched roof, so it provides more complete sun protection and better shelter from rain.
Choose a pergola when you want architectural shade, a lighter visual profile, plant support, or a structure that feels open and connected to the yard. Choose a pavilion when you want a true outdoor room for deep seating, outdoor kitchens, TVs, fireplaces, or year-round entertaining. Both can create a defined outdoor living space; the right choice depends on how much coverage and enclosure you want.
A pergola is a strong choice when you want to define an outdoor space without closing it in. Its open-roof design creates filtered shade while preserving views, airflow, and natural light, making the space feel more intentional without the heavier feel of a full roof.
If your priority is architectural character, partial shade, and an open-air feel, a timber frame pergola is often the better fit.
The right pergola size depends on how the space will be used, where it will sit, and how the surrounding area will be finished. A garden accent or walkway pergola may only need a modest footprint, while a poolside seating area, dining space, or outdoor living zone may need more room for furniture and circulation.
The most important sizing considerations include:
Standard pergola overhangs vary by model:
Series | Model | Overhang |
Summit | Bross | 12 inches |
Reserve | Teton | 18 inches |
Reserve | Acadia | None |
The Reserve Series is Cover Timberworks’ highest quality, most flexible timber frame line. It is designed for customers who want the best version of a timber outdoor structure: more designs, more options, any size, heavier visual proportions, old world joinery, hidden hardware, oak pegs, and a more refined finished appearance. That level of detail and craftsmanship does come at a higher price than more typical carpenter built structures.
The Summit Series was introduced as a bridge between a conventional carpenter built structure and the full Reserve Series. It still carries Cover Timberworks quality, off site CNC fabrication, professional delivery and installation, Douglas Fir timber, and stain options, but with fewer designs, fixed sizes, exposed structural fasteners, smaller timber specifications, and no complex timber frame joinery. In short, Reserve is the premium timber frame line; Summit is the value focused COVER line.
Cover Timberworks offers two timber size packages: Standard and Heavy. The Heavy package creates a more substantial architectural look, but the right choice depends on the scale of the structure. Smaller structures often look best in Standard because the lighter timber proportions fit the overall size. Mid-size structures can often work well in either package. Larger structures usually benefit from the Heavy package because the larger posts, beams, rafters, and braces better match the roof mass, span, and overall visual weight of the design.
One important difference between Cover Timberworks and many field-built carpenter structures is that the timber scale is maintained throughout the structure. Instead of using a large corner post with much smaller framing everywhere else, the posts, plates, rafters, braces, and shade bars are designed as a complete system.
Component | Summit Standard | Summit Heavy | Reserve Standard | Reserve Heavy |
Post | 6×6 | 8×8 | 6×6 | 8×8 |
Plates, girt, ridge | 3×10 | 4×10 | 6×8 or 6×10 | 8×10 or 8×12 |
Rafters | 3×8 | 3×8 | 4×8 | 4×8 |
Knee braces | 2×6 | 3×6 | 4×6 | 6×6 |
Shade bars | 2×4 | 2×4 | 4×4 | 4×4 |
Timber frame pergola pricing can vary widely, but starting prices are useful when you are comparing options and deciding what fits your budget. COVER Timberworks publishes model-based starting prices so customers have a clear baseline before making final design selections.
Current pergola starting price examples include:
| Series | Model | Starting at |
| Summit | Bross | $6,995 |
| Reserve | Acadia | $8,495 |
| Reserve | Teton | $9,295 |
These are starting prices, not final project totals. Larger sizes, Heavy Timber packages, custom details, site conditions, special engineering, and other options can change the final price. Cover Timberworks uses menu pricing and a design and price process so customers can move from general budget expectations to a clear written estimate without the uncertainty of a fully open-ended custom bid.

No, Cover Timberworks does not offer kits in the usual big box or online sense. Many pergola kits are available in only one or a few fixed sizes, have limited options, may be fabricated overseas, use lighter materials, and require the customer to self-install or hire an independent contractor. That is not the Cover Timberworks model.
Cover Timberworks fabricates and stains each structure in its facility using a CNC saw system, then delivers and installs the structure with professional in-house crews. That gives customers the benefits of off-site production and efficient installation without settling for a generic kit. The structures are made to order, available in many designs, options, colors, and sizes, and can be delivered and installed across Texas and beyond.
In select situations, such as certain out-of-state projects, Cover Timberworks may be able to provide a pre-manufactured structure for self-installation. The standard offering, however, is a designed, fabricated, delivered, and installed timber structure. Customers can choose from the COVER lineup for efficiency and value, or pursue a fully custom timber frame solution when the project requires it.
Cover Timberworks focuses on freestanding pergolas and other freestanding timber outdoor structures. This approach is central to the company’s value: pre-engineered designs, menu pricing, off-site fabrication, cleaner installation, and a more predictable project process.
A freestanding pergola can still be placed very close to the home when the site allows. In some cases, the structure can be positioned near an exterior wall to function like a patio cover while remaining structurally independent. Structures that attach directly to a house are more like remodeling projects because they involve the home’s framing, waterproofing, roofline, and other site specific conditions. If your goal is to create coverage right next to the house, Cover Timberworks can help evaluate whether a freestanding solution near the home is the better fit.
Timber and aluminum pergolas serve different priorities. Aluminum can be a good fit when the main goal is reduced maintenance and a sleek metal appearance. The tradeoff is that aluminum pergolas are often more expensive, more limited in design range, colder in appearance, and less natural in the landscape than timber structures.
For customers who want warmth, natural texture, stronger visual presence, broader design options, and better integration with masonry, landscaping, and outdoor living features, timber framing is usually the better fit.
The advantages of timber include:
The primary advantage of aluminum is lower maintenance. The tradeoff is higher cost, narrower design flexibility, fewer finish options, and a colder overall appearance. For customers who want natural beauty, scale, warmth, and a structure that fits comfortably into a finished outdoor living environment, timber framing is usually the stronger choice.
COVER Timberworks uses #1 or better Free of Heart Center Coastal Douglas Fir for its timber structures. Douglas Fir is one of the most widely used species in timber frame construction because it offers an excellent combination of strength, density, stability, and appearance.
For structural pergolas and outdoor timber frame structures, Douglas Fir has several advantages:
Some surface checking is still normal in exterior timber because wood expands and contracts with sun, heat, humidity, and weather. The goal is not to make wood behave like plastic; it is to use a high-quality timber that performs well structurally, finishes beautifully, and has the scale expected in a premium outdoor structure.
Yes. Cover Timberworks structures come stained off site before installation. The stain is a deep-penetrating, oil-based stain and sealer applied before the structure arrives, which helps protect the timber and gives the finished pergola a cleaner, more complete appearance on installation day.
Off-site staining is important because it allows the timbers to be finished in a controlled environment, including areas that are harder to reach once the structure is assembled. It also keeps the jobsite cleaner and reduces the amount of finishing work needed at the home or project site. Cover Timberworks offers nine standard stain colors, with custom colors available when the project requires a specific look.
Permit requirements for pergolas vary by city, county, HOA, and project type. In many Texas communities, a small freestanding, open-roof pergola may not require a building permit, especially if it is under a common size threshold such as 200 square feet and does not include electrical, plumbing, gas, or other utility work. However, local rules vary, and some jurisdictions require permits for accessory structures regardless of size.
The biggest permit factors usually include:
COVER Timberworks provides detailed structural drawings with every project, which can help when permits or HOA approvals are required. Sealed engineered plans are available for an additional cost when required by the local jurisdiction, HOA, builder, architect, or project conditions. Because permit rules are local, homeowners should confirm requirements with their city, county, HOA, or permitting authority before construction.
Most COVER Timberworks projects take about 3 to 5 weeks after the order and structural drawings are approved. During that time, the structure moves through final detailing, production, sanding, staining, delivery, and installation.
Because most of the work is completed off-site in our shop, the on-site installation is usually fast and clean compared to traditional backyard carpentry. Smaller pergolas can often be assembled in as little as a half day, while larger pergolas, pavilions, hybrids, or more detailed structures may take longer.
The timeline can vary based on project size, current production schedule, special design options, engineering requirements, and site readiness. The best way to keep the project moving is to finalize the size, style, orientation, stain color, timber package, and site conditions before production begins.
A timber pergola should be inspected and lightly cleaned once or twice per year. Because pergolas have exposed rafters and shade bars, they receive more direct sun and weather exposure than a roofed pavilion, so finish maintenance is especially important.
Areas with the most sun exposure may need light finish touch-ups every 1 to 2 years. A more complete maintenance coat is commonly needed every 2 to 5 years, depending on sun exposure, finish color, tree coverage, and local weather conditions.
Good maintenance also includes keeping leaves and debris off the structure, checking drainage around the posts, inspecting hardware and anchors, and watching for fading or finish wear. Surface checking is normal in exterior timber and is usually cosmetic, but serious damage, water traps, or finish failure should be addressed.
COVER Timberworks is different because it combines true timber frame craftsmanship with a more efficient, controlled, and predictable project process. Instead of building everything from scratch in the field, our structures are designed through a proven system, cut with CNC precision, sanded and stained off-site, then delivered and installed by in-house crews.
Key differences include:
The result is a structure that feels custom, substantial, and carefully built, while avoiding much of the uncertainty, mess, and inconsistency that can come with a fully field-built backyard project.
A timber frame pavilion is a freestanding outdoor structure with a solid roof, open sides, and heavy timber posts and beams. It creates a covered outdoor room that provides shade, rain protection, airflow, and a strong architectural focal point for patios, pool areas, outdoor kitchens, dining spaces, and entertainment areas.
Compared with conventional carpentry, timber framing relies on larger visible timbers, stronger proportions, and more deliberate joinery. Instead of building the roof structure mostly from smaller dimensional lumber and surface fasteners, a timber frame pavilion uses the posts, beams, rafters, braces, and trusses as both the structural frame and the finished architectural expression.
Key characteristics include:
A pavilion has a solid pitched roof. A pergola has an open roof made from rafters and shade bars. That single difference changes how the structure performs and how it should be used.
A pergola is best when you want partial shade, openness, airflow, plant support, and a lighter visual profile. A pavilion is best when you want more complete sun protection, shelter from rain, a space for deep seating, an outdoor kitchen, a dining area, or a more defined outdoor room. A pavilion generally requires more material, roof planning, and installation work, so it usually costs more than a pergola of similar size and timber package.
A pavilion is a strong choice when you want a true covered outdoor living space. Unlike an open-roof pergola, a pavilion has a solid roof that provides deeper shade, better rain protection, and a more comfortable setting for furniture, appliances, and everyday use.
Key advantages of a pavilion include:
If the goal is comfort, coverage, and a more complete outdoor living space, a timber frame pavilion is usually the stronger choice.
A covered patio usually describes a roofed area attached to the house, often just outside the back door. It is commonly built like a home addition or remodel because it connects to the existing structure and may involve roof tie-ins, flashing, drainage, framing, and other site-specific construction details.
A Cover Timberworks pavilion is a freestanding timber structure. It can be placed near the home to function like a covered patio, but it does not rely on being attached to the house. That freestanding approach allows the pavilion to be positioned where it best serves the property: beside a pool, over an outdoor kitchen, in a larger backyard, near a guest area, or as part of a complete outdoor living plan. It also supports Cover Timberworks’ pre-engineered, menu-priced, off-site fabrication process.
The right pavilion size depends on how the space will be used, where it will sit, and what the finished outdoor living area needs to support. A small seating area may only need a modest footprint, while a pavilion with an outdoor kitchen, dining table, fireplace, TV, and deep seating area needs more room for furniture, circulation, and covered space.
The most important sizing considerations include:
The Reserve Series is the highest quality Cover Timberworks line and is designed to set the standard for timber outdoor structures. It offers more designs, more options, any size, heavier timber proportions, old-world joinery, hidden hardware, oak pegs, and a more refined finished appearance. That level of detail does come at a slightly higher price than more typical carpenter-built structures.
The Summit Series was introduced as a bridge between typical field-built construction and the full Reserve Series. It still delivers Cover Timberworks quality, off-site CNC production, professional delivery and installation, Douglas Fir timber, and stain options, but with fewer designs, fewer options, fixed sizes, smaller timber specifications, exposed fasteners, and no complex joinery. It is designed to compete at a price point similar to or better than many conventional carpenter-built structures while still offering the benefits of the COVER process.
The difference between the Standard and Heavy Timber packages is the size and scale of the timbers used throughout the structure. Both packages are true timber frame construction, but the Heavy package uses larger components in key areas such as posts, plates, braces, and roof framing. This creates a stronger visual presence and gives larger structures better proportion between the timber frame, roof size, and span.
The right choice is mostly a question of scale. Smaller structures often look great in Standard. Mid size structures can go either way. Larger pavilions usually look best in Heavy because the larger timbers better match the overall roof mass and visual weight of the structure.
COVER Timberworks also keeps the timber scale consistent throughout the frame. Many carpenter built structures use a large corner post but then switch to much smaller framing elsewhere. COVER designs the posts, plates, rafters, braces, and roof components together so the entire structure feels properly scaled.
The table below shows the typical timber size differences:
Component | Summit Standard | Summit Heavy | Reserve Standard | Reserve Heavy |
Post | 6×6 | 8×8 | 6×6 | 8×8 |
Plates, girt, ridge | 3×10 | 4×10 | 6×8 or 6×10 | 8×10 or 8×12 |
Rafters | 3×8 | 3×8 | 4×8 | 4×8 |
Knee braces | 2×6 | 3×6 | 4×6 | 6×6 |
Roof decking, standard | T1-11 | T1-11 | 1×6 T&G | 1×6 T&G |
Cover Timberworks offers multiple pavilion designs across its product lines. The Summit Series includes three pavilion designs, while the Reserve Series includes ten pavilion designs, along with custom solutions when the project requires something outside the standard design menu.
This gives customers a practical range: simple fixed-size pavilions for value-conscious projects, more detailed Reserve pavilions for premium outdoor living spaces, and custom configurations for unique properties, pool environments, commercial areas, or large entertainment spaces. The right design usually depends on roof style, size, budget, architecture of the home or property, and how the space will be used.
Cover Timberworks pavilion pricing typically includes a complete roof system with 30-year dimensional shingles. Roof appearance can be selected to coordinate with the home or surrounding architecture, and popular upgrades include R-panel and standing seam metal roofing. Other roofing materials may be available depending on the project requirements.
The underside of the roof matters too because it affects the finished look from below. Common decking or ceiling options include tongue-and-groove, T1-11, purlin, or slat-style treatments depending on the series and design. Reserve Series pavilions commonly use 1×6 tongue-and-groove decking for a more refined timber-frame ceiling, while Summit Series pavilions use a simpler standard roof decking approach with upgrade options available.
Timber frame pavilion pricing varies by size, series, timber package, roof system, decking or ceiling option, stain, site conditions, and any required engineering or permitting support. The Summit Series is less expensive because it uses fixed sizes and a simplified design package. The Reserve Series costs more because it offers more design flexibility, heavier detailing, and traditional timber frame joinery.
Current pavilion starting price examples include:
| Series | Example model | Starting at |
| Summit | Huron pavilion | $9,545 |
| Reserve | Bryce pavilion | $11,695 |
| Typical mid size pavilion | Various | Around $15,000 to $17,000 |
| Large pavilion | Various | Often over $20,000 |
These are starting prices and planning ranges, not final project totals. Final pricing depends on the selected model, size, timber package, roof option, finish, access, site conditions, and project specific requirements. COVER Timberworks uses a design and price process so customers can move from general budget expectations to a clear written estimate before moving forward.

No. Cover Timberworks focuses on freestanding pavilions. Attached pavilions are more like remodeling projects because they connect to the home and can involve roof tie-ins, waterproofing, drainage, framing, flashing, and other site-specific conditions that fall outside the repeatable Cover Timberworks process.
The freestanding approach is what makes Cover Timberworks’ system efficient and valuable: pre-engineered designs, menu pricing, off-site fabrication, controlled staining, professional delivery, and a faster, cleaner installation. A freestanding pavilion can often be placed close to the home when the site allows, but it remains structurally independent. That approach gives more placement flexibility and avoids turning the project into a house remodel.
COVER Timberworks uses #1 or better Free of Heart Center Coastal Douglas Fir for its timber pavilions. For pavilion construction, timber selection matters because the structure supports a full roof system and often spans larger outdoor living areas. Douglas Fir is well suited for this use because it offers a strong balance of structural performance, density, stability, and finished appearance.
For timber frame pavilions, Douglas Fir has several advantages:
Some surface checking is still normal in exterior timber because wood expands and contracts with sun, heat, humidity, and weather. The goal is to use a timber that performs well structurally, finishes beautifully, and has the scale expected in a premium pavilion.
Yes. Cover Timberworks pavilions are stained off site before installation. This allows the timbers to be finished in a controlled environment and helps protect all sides of the wood, including areas that are more difficult to access after assembly.
Off-site staining also keeps the jobsite cleaner and makes the installation process more efficient. Cover Timberworks offers nine standard stain colors, and custom colors can be used when a project requires a specific match or design direction. Because the stain is a penetrating oil-based finish, it is intended to enhance the wood rather than hide the natural character of the timber.
In many Texas communities, freestanding pavilions are treated as detached accessory structures, similar to pergolas, gazebos, sheds, and other backyard structures. Whether a permit is required usually depends on local rules, the size of the pavilion, whether it is attached to the home, whether it includes utilities, and where it sits on the property.
Some jurisdictions exempt small detached accessory structures below a certain size, often around 200 square feet, while others require permits for roofed outdoor structures regardless of size. Because there is no single statewide Texas rule, homeowners should confirm requirements with the local permitting authority.
The most common permit factors include:
COVER Timberworks provides detailed structural drawings with every pavilion project, which can help with permitting, HOA review, builder coordination, and project planning. Sealed engineered plans are available for an additional cost when required by the city, county, HOA, builder, architect, or project conditions.
Once the order and structural drawings are approved, the full process generally takes about 3 to 5 weeks, but this can vary depending on the product, production schedule, project size, and site readiness. The process includes final selections, structural drawings, CNC production, sanding, staining, delivery, and installation.
Because the timber frame is fabricated and finished off site, the on-site work is much faster than a traditional field-built structure. In a typical pavilion installation, the timber frame can often be assembled in one day, with the roof installed the second day. Larger pavilions, complex roof systems, site constraints, or special options can extend the installation timeline.
A timber pavilion should be inspected and cleaned periodically, with special attention to the roof, stain finish, anchors, hardware, drainage, and any areas where water or debris can collect. Because a pavilion has a solid roof, the roof system should also be checked for shingle or metal roof wear, flashing conditions where applicable, and storm related damage.
As a practical rule, we recommend a simple seasonal inspection and light cleaning once or twice per year. Areas with heavy sun exposure may benefit from light finish touch ups every 1 to 2 years, while a more complete maintenance coat is commonly needed every 2 to 5 years depending on exposure, finish color, tree coverage, and local weather conditions.
A pavilion generally protects many overhead timber elements better than a pergola, but it is still an exterior wood structure and benefits from routine care. A seasonal inspection is usually enough to catch small issues before they become expensive problems.
COVER Timberworks is different because it combines timber frame craftsmanship with a more controlled and predictable way to design, price, fabricate, and install outdoor structures. Rather than treating each pavilion as a one off backyard carpentry project, COVER uses a proven design system, clear menu pricing, CNC precision cutting, shop fabrication, professional finishing, and experienced installation crews.
Key differences include:
The result is a pavilion that feels substantial, carefully built, and custom to the space, while avoiding much of the uncertainty, mess, and inconsistency that can come with a fully field built project.
A hybrid structure combines more than one outdoor structure type into a single coordinated design. For Cover Timberworks, that usually means a pavilion with an attached pergola, a pavilion with a lean-to, or a pavilion with both a lean-to and pergola. The pavilion provides the main covered outdoor room, while the additional wings or components create one or more secondary functional zones.
Hybrids are especially useful when one simple roof form is not enough for the way the space will be used. A covered pavilion area may serve as the living room, a pergola may define dining or poolside seating, and a lean-to may support an outdoor kitchen or service area. The result is one larger timber structure that organizes the outdoor living space instead of leaving every activity under one undifferentiated roof.
A lean-to is an additional roof section that continues from one side of a pavilion at a lower pitch and is supported by additional posts. It is part of the overall structure, but it creates a secondary covered zone with a different roofline and a more specific purpose.
Lean-tos are often used for outdoor kitchens, dining areas, serving zones, storage, enclosed areas, or transition spaces beside the main pavilion. Because the roofline changes and additional posts are introduced, a lean-to also helps visually separate one outdoor function from another. Instead of one large open rectangle, the space begins to feel more like a planned outdoor living layout with distinct rooms.
A hybrid structure is ideal when you want a larger, more complete outdoor living space with more than one function. It can combine a covered pavilion area with an open pergola area, a lean-to kitchen zone, or both. That makes it easier to support dining, lounging, cooking, entertaining, and poolside use in one coordinated timber structure.
The biggest advantage is organization. The changing rooflines and added posts naturally define separate areas, so the space feels designed instead of oversized. A hybrid can anchor a backyard, create a strong architectural focal point, and make a large outdoor area easier to furnish. It is typically best for customers who want more than a simple shade structure and are planning a complete outdoor living environment.
Yes. An attached pergola can be added to any Reserve Series pavilion. This is a strong option when you want the covered comfort of a pavilion plus a more open-air zone for dining, poolside seating, transition space, or architectural balance.
Adding a pergola to a pavilion also helps create multiple outdoor zones without separating the structures visually. The pavilion can serve as the main covered living area, while the pergola can define a lighter, more open space nearby.
A lean-to can be added to many Reserve Series pavilion designs, but it is not available in the Summit Series. There are also design limitations: lean-tos are not a fit for every roof style, including certain Denali, Zion, half-hip, or hip-roof configurations.
The reason is structural and architectural. A lean-to changes the roofline, adds posts, and creates a secondary covered zone, so it has to work with the pavilion’s roof form and engineering. When it is a good fit, a lean-to is especially useful for outdoor kitchens, dining areas, serving spaces, or a protected transition area beside the main pavilion.
Yes. Double lean-tos and/or pergolas can be added to the right pavilion design. These larger hybrid layouts can create a balanced or symmetrical architectural look while giving each side of the structure a specific purpose.
For example, one side might become an outdoor kitchen, another might become a dining area, and the main pavilion can remain open for seating or entertaining. Because these larger hybrid designs affect rooflines, post placement, spans, and circulation, they should be planned carefully through the Cover Timberworks design process rather than treated as simple add ons.
No. Hybrid structures are not offered in the Summit Series. The Summit line is built for value, speed, and simplicity, using fixed-size designs and a more limited set of options.
Hybrids require more design flexibility because they combine roof forms, post layouts, spans, and functional zones. That makes them a better fit for the Reserve Series, where the design system supports more customization, larger layouts, and more detailed outdoor living plans. If you want a pavilion with a pergola, lean-to, or both, the Reserve Series is the appropriate starting point.
Hybrid structure pricing depends on the base pavilion, the added pergola or lean-to, size, timber package, roofing, stain, site conditions, and any required engineering or permit support. Because hybrids add roof area, posts, beams, layout complexity, and installation time, they cost more than a standalone pavilion of the same main footprint.
As starting price examples, an attached lean-to option starts at $8,845 and an attached pergola option starts at $8,145. Those are add-on starting points, not complete hybrid project prices by themselves. The final cost should be confirmed through the design and price process after the base pavilion, attached component, size, orientation, and finish selections are defined.
