What term describes a basic building method that relies on large posts and beams for support?

The term that describes a basic building method relying on large posts and beams for support is "post and beam construction." This structural system uses vertical posts and horizontal beams to create frameworks that support the building, allowing for larger open spaces without the need for internal walls. This method is often praised for its strength and ability to withstand various loads, which makes it suitable for both residential and commercial buildings.

Post and beam construction contrasts with frame construction, which typically utilizes smaller studs and may include additional materials to provide support, but doesn't emphasize the use of large beams and posts in the same foundational manner. Therefore, the essence of post and beam construction is its straightforward reliance on these substantial elements to create a robust structural framework.
