Douglas Fir (DF) is often the standard against which all other framing species are measured. Its strength combined with a superior strength-to-weight ratio, high specific gravity (for excellent nail and metal truss plate-holding capability), excellent dimensional stability (giving "green" DF products the ability to season well in service), the.
The timber components were manufactured off-site to cause less disturbance to the natural surroundings. The steel understructure provides load-bearing support to a solid Douglas-fir wood deck, posts, railings and an overhanging roof.
Much of the materials, labour and construction expertise were sourced locally. Blending old world workmanship with the latest technologies, we design & supply pre-cut, test-fitted timber frame and glulam structures from West Coast Douglas fir and Cedar. Sincewe have worked all over the world on a range of projects from custom timber frame homes to elaborate commercial and civil structures.

Douglas fir is commonly found as sawn timber in weather-protected heavy construction applications such as mining timbers, posts and poles. Treated pilings and boards are used in marine structures and for landscaping.
Other common applications include general house framing, flooring, lining, fascias, bargeboards and pergolas. An important consideration in the roof design is the diameter of the timber used for the beams. Six metre lengths of Douglas fir, approximately mm diameter at the base, were felled approximately six months before fabrication.
As the project was intended to be an exemplar of low-carbon construction, these timbers were used green. The Timber Roof Structure The building’s triangular form makes maximum use of the site, resolves differences in site levels and creates a horizontal plane on which the roof structure stands.
The roof support structure consists of five vaults of glulam timber arches; they span 18 metres, rising from the ground like trees in an uplifting. Therefore, we have chosen eastern white pine and Douglas fir as our primary materials to fashion our timber frames.
High quality Douglas fir and eastern white pine are the most stable green materials we have ever worked with, offering our customers a superior frame that will endure for generations. Other species are available upon request.
The foot-high roof is supported by 15 glulam arches—designed with structural engineers Fast + Epp—spaced every 47½ feet along the length of the building.
The arches are made of two layers of Douglas fir glulam sandwiched around steel ribbing reinforcement. Douglas fir, genus of about six species of evergreen trees of the conifer family Pinaceae, native to western North America and eastern Asia.
They are important timber trees and produce strong wood. Several are grown as ornamentals and are common Christmas trees in North America. For face-mount hangers and straight straps, use of Douglas fir table loads for spruce-pine-fir.
A fastener that splits the wood will not take the design load. Evaluate splits to determine if the connection will perform as required. Dry wood may split more easily and should be evaluated as required.
