Oak Frame Types.
At Oak Frames Direct, we provide a wide range of timber-framed building solutions designed to meet the needs of commercial developers, architects, and trade professionals. Our oak frame structures combine traditional craftsmanship with precision engineering, offering reliable options for projects that demand both practicality and visual appeal. From the classic Main Span configuration, capable of supporting spans up to 8m, to the adaptable Aisled Barns with high eaves and extended internal floor space, our frames are built to deliver strength and flexibility across a variety of applications.
With options such as the Main Span with Rear Aisle and multiple first-floor layouts, including designs with or without central posts, we supply frames that balance functionality with efficiency. Additional solutions such as the Raised Plate, Sling Brace, Two Storey, and Lean-To, as well as contemporary styles like the Monopitch and Flat Roof, provide a full range of options for different project requirements.
Whether you are sourcing frames for commercial developments, agricultural buildings, or bespoke structures with height restrictions, our oak frame range ensures you can specify the right design for your client’s project while maintaining efficiency in build and long-term durability.
Main Span Oak Frame
The building maintains the same height at the rear as at the front. We can provide spans up to 8m, and any span over 6m requires a truss roof construction.
Main Span with Rear Aisle
An aisle at the rear allows greater building depth while keeping ridge height lower. The aisle roof pitch is usually shallower than the main roof and can extend to practical depth limits. Maximum span is 8m, with truss roofing required for spans above 6m.
Aisled Barn
This configuration has a high central eaves height with side aisles to maximise usable floor space. As with other designs, spans up to 8m are possible, with truss roofing necessary for larger spans.
Main Span with First Floor and Central Post
First-floor options can be added to most frames. A central post under the tie beam supports the load. Suitable for spans up to 8m.
Main Span with First Floor without Central Post
This option provides first-floor space without a central post, but with reduced upstairs height due to the larger tie beam needed to take the load. Posts also need to be increased in size. The maximum span for this type is around 6.4m.
Raised Plate with Central Post
This offers more roof room compared to the Main Span with First Floor. A central post under the tie beam supports the floor load. Suitable for spans up to 8m.
Raised Plate without Central Post
Provides extra roof room compared to the Main Span with First Floor, but spans are limited to around 6.4m.
Sling Brace
This design creates a one and a half storey structure, incorporating sling braces within the upstairs space. The maximum span is about 6.4m. This type is less adaptable for L-shaped or T-shaped layouts due to the eaves beams at waist height.
Two Storey
A standard two-storey construction suitable for a range of commercial or residential applications.
Lean-To
This attaches to an existing structure with a wall plate to pitch the roof from.
Monopitch
A free-standing, self-supporting version of the lean-to design.
Flat Roof
Used for projects with height restrictions, this standard flat roof design can incorporate glazed lanterns for additional internal light.
Pitched Roof with Flat Roof
A pitched roof cut off with a flat top, often used where there are height limitations or to maintain upstairs views from existing windows. This can also feature glazed lanterns for improved light.
