American Purlin Series

Precision-Cut Timber Frames Inspired by American Tradition

There is something timeless about a true timber frame.

For centuries, heavy timber structures have defined the American landscape — barns rising from farmland, carriage houses beside old roads, workshops where generations worked beneath massive beams. These buildings were not simply constructed; they were crafted to endure, their joinery locked together with wood against wood, designed to stand for generations.

The American Purlin Series carries that tradition forward — combining the beauty of historic timber framing with the precision of modern CNC fabrication.

Each frame in this series is cut using advanced CNC timber machinery to the highest standards in the industry. Every mortise, tenon, and shoulder is machined with exceptional accuracy, allowing the frame to fit together cleanly and efficiently when it arrives on site. The result is a structure that raises smoothly, assembles predictably, and achieves a level of precision difficult to match with conventional construction.

These frames follow classic purlin roof systems, a hallmark of traditional American timber architecture. This method allows for larger spans, cleaner interior spaces, and the ability to incorporate lofts, vaulted ceilings, or fully enclosed buildings with ease. The exposed structure becomes the architecture itself — honest, structural, and visually striking.

Our American Purlin Series frames are produced by one of the most respected timber frame manufacturers in the country and made available through us as complete timber frame kits. Each kit includes precision-cut structural timbers and detailed shop drawings to guide assembly.

We supply these frames in Southern Yellow Pine, a species prized for its strength, stability, and warm golden color that ages beautifully over time.

Like all of our frames, these are made to order. Sizes, layouts, and details can often be adjusted to suit your project — whether you're building a garage, workshop, guest house, pavilion, or full timber frame home.

This series represents the highest standard of timber frame fabrication available today — traditional architecture brought to life with modern precision.
