Whole Tree Creates Unique Interiors

Whole Tree Creates Unique Interiors BUILDINGS Miscellaneous Ronald Gundersen and his company Whole Trees Architecture uses whole trees for everything from structural components to interior decorating including stairs railings and exposed columns “We work on homes as well as commercial buildings where whole trees compete with concrete and steel ” explains Amelia Swan co-owner “As steel and concrete prices go up and the ability to import materials becomes more challenging we think people will see that whole tree building makes sense economically ” The USDA Forest Products Research Laboratory has shown that whole trees are 50 percent stronger in axial loading and bending than milled lumber of comparable size Milling they found removes the strongest and outermost layers of the tree that are pre-tensioned to resist wind shear The company is headquartered in a steep-sided tree-filled valley in southwestern Wisconsin They do their planning and consulting from living quarters and office areas that were built with whole trees They also prepare and harvest trees from the 140-acre woodlot for use in clients’ buildings They have a computerized inventory of more than 1 000 trees that are ready for harvest “The software stores length base and top diameter potential as single or double pieces natural curves or arches as well as the GPS location of the tree ” says Swan “We can pull up photos of the trees as well ” Once a client has approved a design trees will be selected from the inventory Selected trees will already have been girdled bark peeled and allowed to dry in place in the woods for 6 months or more In that time a tree will lose up to 50 percent of its weight in water making it easier and less expensive to move If necessary trees may also be dried in a simple solar kiln “The slower the tree dries out the less checking or longitudinal cracking that occurs ” explains Swan “It has no affect on the structural integrity or strength of the tree only on its appearance ” Even green trees can be used in building adds Swan As they dry in place they will shrink in diameter but not to any noticeable degree in length Whole tree construction costs around $125/sq ft fall at the low end of custom construction says Swan By comparison a conventional stick built home would be less but a post and beam home starts at $145/sq ft and moves up to $180 or more Swan explains that the company operates at multiple levels depending on a client’s needs They can develop plans provide trees act as general contractors or do all these Clients may want local trees on site to be used and Gundersen’s crew will harvest and prep them Contact: Whole Trees E2890 Lorenz Road Stoddard Wis 54658 ph 608 452-3894; cell 608 317-2427; ameliaswan@wholetrees com; www wholetrees com
