Hi Tim,

I'll do my best on this...and perhaps it will make more sense to you after reading this post...If not let me know, as I am always trying to better define this for folks...client and Timberwrights alike...Thanks for you input in advance... smile

I can't see pricing a frame by the square foot of the building or board foot of timber, both being very different things.


Remember...this is for the "client" as a metric of understanding. How we arrive there is based on many specific elements...most importantly perhaps...experience cutting many different kinds of frames, in many modalities and across many markets, as well as, examining different markets and metrics of pricing...

All my work is priced on the individual frame, they are all different.


Agreed...They are all different...and have countless variations. This does not change commonalities or abilities to dial in pricing. As complicated as a timber frames (or sky scrapers) can be...it isn't as complicated as say "plastic surgery" or other disciplines...these all carry (and have) set averages into "pricing metrics."

Again (this is not aimed and anyone individual...I do want to stress that) this is what separates "experience professionals" from those with limited exposure and/or time performing an activity in a range of markets and disciplines.

The base of my calculation is the joinery. Other consideration are bent spacing and how complicated the joinery decisions will be.


EXCELLENT...!!!...As it has been for a very long time (millenia??)

This is (for many of the woodworking arts) the primary focus for arriving and a pricing metric..The joint cut!!

I have observed a number of both historic and contemporaneity examples of this both here and overseas. There seems to be an average of between 5 and 10 levels of complexity for each joint type (which is made of usually 2 executions.) For example a simple 90 degree cut on the end of an exposed rafter tail would be a "level one" execution and have a price to go with it. A 4 way intersection in some of the more complicated Asian joinery, or Valley rafter mortise and tenon joint would be a "level 10" and have a higher $$$ amount assigned to it.

From here we can extrapolate either a "board foot" or "square foot or metre" pricing modality. Both of which has significant historic examples of being applied to profession like traditional house, timber, wood, and ship Wrights of all fashion and in many different cultures...With the "Shipwright" also employing the "volume of the ship" as an indicator of cost to their clients...

Will you be lodging joist and purlins or using pockets? Compound joinery or not? What is the finish of the timbers expectation, planed, sanded, oil, raw with no finish at all, dirt included. Bent spacing on a building can double the price alone, with no other factors.


Some of these are "add on" costs...

For example, planning/sanding and Oiling/Staining typically has a linear foot cost preside finished. This currently ranges (US/Canada) between $1.75 to $6.00 depending on treatment, and/or materials applied.

Bent spacing can indeed affect price...Yet that does not negate "averages" or the application of a "metric" if a craft (aka "skill set application") of any type is well understood by the practicing artisan or professional.

How do you consider all these factor when using a square foot number?


Work backwards from the "know elements." Wood species, complexity of joint, material cost (if included), tooling, etc.

I stress again, whenever this debate tends to come up, it is often with folks with 15 years of experience or less. That isn't a "bad thing" or a criticism of any kind...just and observation. I would share, in days of old, typically a "Master Apprentice" would still be working with and under a "Master-Wright" at the 15 year mark in their career. They typically would not leave a "guild shop" or their relationship with a group of Master Craft people (I am speaking across many art/craft forms from timber framing to Blacksmiths) until the 30 year or more mark...Some never leave and only take over after the Master Wright has passed. I have met "apprentice" in Japan that are in their 40's and some even older...

Today we have lost much in these "student/teacher" relationships that span generations within many arts and crafts. The deeper knowledge these "teaching systems" had provided in the past are vastly different in the modern economic models today...with that much happening today...a great deal of complexity and skill sets are lost (or not taught) before a "timber framer" is expected (or chooses) to then go out and market and sell their product.
