COVER Timberworks maintains heavy timber scale through the posts, beams, rafters, and braces. Larger members create more shade, allow for stronger timber frame joinery, support wider open spans when the design allows, and give the finished structure a more consistent heavy timber appearance.
Heavy timber construction also allows for hidden hardware, housed structural knee braces, and cleaner connection details than many conventionally framed structures. The result is a pergola or pavilion that looks and functions like a substantial outdoor structure, not a light patio cover with oversized posts added for appearance.
COVER Timberworks uses heavy timber throughout the structure, creating a stronger, more durable, and more architecturally balanced frame than standard carpentry built with smaller dimension lumber. The difference is visible in the scale, but it also affects shade, spans, fire performance, connection design, and long term durability.
- Heavy timber throughout: We maintain substantial timber sizing across the entire frame rather than using large posts with lighter beams, rafters, or braces. This creates a balanced scale and a more cohesive architectural appearance.
- Greater durability: Larger timbers contain more material and are better suited for long term outdoor exposure. They are less vulnerable to minor surface deterioration and provide greater structural mass over time.
- More shade: Deeper beams, rafters, and other overhead members cast more shade than smaller framing lumber, adding practical comfort beneath a pergola.
- Larger open spans: Heavy timber can support wider spans, reducing the need for unnecessary posts and creating more open, usable outdoor spaces.
- Improved fire performance: Many of our heavy timber components meet mass timber sizing. Larger members resist fire differently than smaller lumber because the exterior chars while the inner core retains strength longer.
- Greater stability: The added weight and substantial connections of a heavy timber frame create a more stable structure, particularly in demanding wind and weather conditions.
- Traditional joinery: Heavy timber allows for mortise and tenon, dovetail, housed brace connections, and other joinery that is not practical with smaller dimension lumber. These methods support distinctive designs while reducing reliance on exposed plates, brackets, and conventional fasteners.
- Precision fabrication: COVER structures are designed as complete systems and cut with CNC equipment before arriving at the jobsite. Standard carpentry is more often measured, cut, and assembled piece by piece on location.
Standard carpentry can produce a functional patio cover, but heavy timber construction delivers a different level of strength, scale, craftsmanship, and permanence. A COVER structure is designed to look and perform like a true architectural addition to the property.

Even the Summit Series uses larger members than standard carpentry.
