Post and Beam vs Stick Frame

Like the look of post and beam, but not sure how it compares to a conventional (stick frame) building?

Here we discuss four of the key structural differences.

1) Bent/Truss Spacing

Post and Beam:
Twelve feet between bents

Stick Frame:
Two feet between trusses

Legacy Post and Beam buildings get their strength from ‘bents’ that are built from 6 inch thick fully dimensional Douglas fir timbers.

Stick frame buildings are supported by wood trusses built from 2 inch thick dimensional lumber. These are durable pieces of wood – but a large number are needed to provide the strength to support a structure.

When you compare that to the post and beam bents, the load bearing capabilities of the 6 inch thick wood is significantly higher, which ultimately allows for larger spaces between the supporting sections.

2) Interior Walls

Post and Beam:
Not needed for strength. Customers add interior walls to meet floorplan preferences.

Stick Frame:
Supporting walls are required and can dictate/limit floorplan options.

3) Visual

Post and Beam:
Since fully dimensional timbers are used, the natural beauty can be left exposed according to owners tastes.

Stick Frame:
Structural components are not appealing and must be covered up completely with drywall or other materials.

4) Second Story/Loft

*Blue Outline = Usable Space

Post and Beam:
As you can see in the picture below, the second story of a post and beam building has a significant amount of usable space. By simply adding floor joists and flooring materials this space can be finished from corner to corner as desired by the customer.

Stick Frame:
To use the second floor in a conventional building, attic trusses are needed that close off the sides and allow only the center square to be utilized.
