Plank Frame Barn Construction

In Short

This book serves as a technical manual and advocacy piece for a revolutionary approach to agrarian architecture. By replacing traditional heavy-timber, mortise-and-tenon construction with a system of built-up planks, the author demonstrates how to build barns that are stronger, cheaper, and significantly faster to erect. It has lasted because it captures a pivotal moment of transition in American farming, offering a timeless lesson on the efficiency of using smaller, readily available materials to achieve superior strength through geometric principles and intelligent structural design.

The Story

The narrative arc of the book follows the evolution of a practical solution to a chronic problem: the scarcity of large-growth timber and the inefficiency of old-fashioned barn building. At the opening, the reader is introduced to a system that began as a crude, experimental method in the Central West some twenty years prior to 1904. The author frames this not as a mere construction tip, but as a superior alternative to the cumbersome, labor-intensive practices of the past. He argues that the traditional methods—which required cutting massive beams and laboriously carving out mortises—were wasteful and prone to decay where moisture inevitably gathered in the joints.

As the text progresses, the author methodically dismantles the necessity of such techniques. He presents his own "plank frame" system, which utilizes standard, smaller-dimension lumber—often 2x8s or 2x10s—spiked together in layers. The story of the system is one of refinement. Through trial, error, and "severe tests," the method moved from local novelty to widespread adoption across thirty-two states. The author guides the reader through the anatomy of this new barn: how the "self-supporting arch roof" functions, how the basement and superstructure are integrated into a single, rigid frame, and why the absence of obstructive interior timbers is essential for modern farm operations like threshing and hay storage.

The middle of the book functions as a masterclass in application. It moves beyond theory into the specific, demonstrating how this system can be applied to diverse structures, ranging from vast dairy barns to skating rinks and amphitheaters. The author acknowledges the skepticism of traditionalists, addressing their concerns about the "frail appearance" of the new frames with empirical evidence: reports of small models supporting the weight of multiple men and actual structures surviving violent windstorms that leveled the surrounding forests.

The final section reveals a collaborative, living project. The author invites criticism from the field, allowing other builders to propose their own designs and raise questions about bracing and stress. He acts as the final arbiter, gently correcting novices who might miscalculate the structural requirements of a 12-sided barn or the bracing needs of a 30-foot span. The book concludes on a note of confidence, asserting that for those who follow the specifications, the plank frame offers a permanent, cost-effective, and superior way to house the bounty of the land.

How It Unfolds

The argument for change The text establishes the limitations of traditional timber framing, highlighting the waste of material and the unnecessary complexity of mortise-and-tenon joints. It posits the plank frame system as a modern, common-sense evolution that saves time, timber, and the frustration of traditional construction.

The blueprint of the system Detailed technical breakdowns describe how individual bents are constructed using 2x8 and 2x10 planks. Diagrams and textual instructions explain how to assemble these components on the ground to form a self-supporting, braced skeleton.

The test of utility Practical examples, such as the rapid raising of a 40x80 barn in just four days, illustrate the system's efficiency. The author shares accounts of successful, long-standing buildings to prove that speed and material savings do not compromise structural durability.

A community of practice The book transitions into an exchange of letters with readers who seek advice on their own building projects. The author critiques these plans, offering corrections and refinements that demonstrate his expertise and the versatility of his design principles.

The final synthesis The concluding chapters synthesize the feedback from other builders, reinforcing the importance of the triangle as the core geometric unit for structural strength. It leaves the reader with a clear understanding that the system is a flexible toolset rather than a rigid, singular model.

The People

The central figure is the author, John L. Shawver, a practical builder and advocate. He is a man of precision and logic, driven by the desire to eliminate waste and modernize farm infrastructure. He sees the "old style" of building not just as slow, but as fundamentally illogical, and he acts as a mentor to those willing to learn the new ways.

Opposing him, or rather, acting as a foil, are the traditionalists—builders and farmers who are initially skeptical of the "frail appearance" of the plank frames. Their concerns serve as the catalyst for Shawver to explain his work more clearly and provide the empirical proofs that validate his methods.

Then there are the correspondents, such as "S. H." from Minneapolis, "N. B." from New Brunswick, and "C. G." from Vermont. These individuals represent the broader community of farmers and builders eager to improve their own operations. They are hungry for technical knowledge, willing to submit their own designs for critique, and demonstrate a shift in the farming culture toward a more collaborative, scientific approach to building. Through their interactions, they evolve from tentative learners into practitioners, each finding that the plank frame can be adapted to their specific needs, whether for a dairy barn or a multipurpose auditorium.

In Its Own Voice

The system has been in use in Central Ohio for the past 20 years, and has been rapidly growing in favor wherever people have had an opportunity of investigating its merits.

This sentence sets the historical context for the rise of the plank frame method.

In an old style framing if a piece was too short it required considerable labor to remedy the matter, and a loss of both timber and strength was sustained.

The author contrasts the wasteful nature of traditional framing with the flexibility of his own design.

The geometrical triangle is the strongest figure one can secure, and it is with that idea always in mind that we do our barn work.

This observation provides the core geometric principle behind the strength of the plank frame system.

What It's Really About

At its heart, this is a book about the democratization of building knowledge. It argues that architecture should not be a secret held by master carpenters, but a transparent, logical process accessible to the farmer. It explores the tension between tradition—often defined by waste and unnecessary complexity—and a forward-looking, industrial pragmatism. The underlying question is how to do more with less: how to build structures that are stronger, more versatile, and more durable while using the smaller, less expensive materials available in a landscape where old-growth forests have vanished. It is a testament to the belief that human ingenuity, when applied to simple materials, can create lasting, large-scale results.

Why Read It Today

Readers who appreciate industrial history, DIY manual culture, or the evolution of American farming will find this book deeply rewarding. It offers a rare, granular look at the technical challenges of the early 20th century, capturing the voice of a man who truly believed that better building practices could improve the lives of farmers.

The experience of reading it is similar to stepping into a dusty, well-organized workshop where a master builder is explaining the "why" behind every nail and brace. It is precise, occasionally repetitive, and entirely focused on the task at hand. While the book is technical and assumes a level of comfort with construction terminology, its warmth shines through in the author’s genuine desire to help others succeed.

What stays with you is the sheer optimism of the period. The book stands as a relic of a time when the "new way" of doing things was synonymous with progress and the efficient use of resources. Despite the age of the text, the core message—that we should constantly evaluate our traditions against the evidence of their efficiency—remains as sharp today as it was in 1904. It is a quiet, sturdy, and honest guide that respects the intelligence of the reader.
