Final answer:
Pier and beam construction, made from hardwood or softwood timbers, rests on a foundation and requires high woodworking skills.
Step-by-step explanation:
The type of post and beam frame that rests on a foundation, is made from either hardwood or softwood timbers, and requires a high degree of woodworking skills is a pier and beam construction.
Pier and beam construction is a technique that involves raising the floor several feet above the ground on platforms of stone or brick. This helps protect the flooring and framing from termites, wood rot, and flooding. It also allows for cooling breezes to pass under the house.
This method requires skilled woodworking because it involves precision to ensure the proper installation of vertical timbers and the construction of the raised platform.
