The expression denotes readily accessible blueprints and instructions for constructing open-sided structures using post-and-beam techniques. These resources enable individuals to build such a structure without incurring the initial cost of purchasing designs. An example would be a downloadable PDF outlining the dimensions, joinery details, and material lists for erecting a small, rectangular shelter.
Availability of such resources can promote wider adoption of traditional building methods. It lowers the financial barrier to entry for those interested in timber framing and allows individuals to personalize these designs, adapting them to specific needs and aesthetic preferences. Historically, communal structures were frequently built utilizing shared knowledge, and freely available designs represent a continuation of this principle.
