dESIGN
Every timber frame entrance design is a journey to the designation of our clients dream. Our drawings bring alive the craftsman’s tradition of timber framing.
|
Our design talent, including the use 3D CAD SOFTWARE & structural design software, are learned from construction experience and a love of timber framing. We admire timber framing for the craft and tradition.
|
The structural team applies proven methodology to each design to make each structure a work of art and structurally adequate. From complex post-and-beam structures to a simple framed canopy we enjoy all types of projects.

Engineering
We offer practical designs that we hope exceed our clients expectations.
|
We believe that the fast delivery of engineering services and drawings don't have to be at the expense of vision and creativity own words.
|
Our firm likes to focus and specialize in timber frame entrances to buildings.

General Engineering Principles We Use In Our Designs
The following are some of the engineering principles we use for timber design:
- Wood pegs are typically specified as Oak.
- If the wood species of the timber is unknown then we usually assume Northern.
- Moment connections are avoided for wood connections. Wood braces are designed for compression only.
- Old growth wood is stronger than new wood. Old growth wood was harvested from dense forests where trees had to compete for light. As a result the trees grew slower and have tighter growth rings (i.e. tighter wood fibers). Tighter wood fibers greatly reduce the crushing of wood perpendicular to the grain. It also increases the capacity of the wood in compression, tension and shear.
- We usually grade the timber before construction. Timber without a considerable number of knots is preferred.
- We prefer to use all wood connections but if the loading requires concealed mechanical connections we like to use Sherpa, Rothoblass, Pitzl & SDD fasteners.
