Client Sourced Timber
Can we use a client's own timber, sourced on-site?
On the face of it, the idea of using a client's own timber harvested on or
near the site has great merit. The use of locally sourced materials has an
appealing integrity to it and can have fewer environmentally damaging consequences.
However...
There are factors relating to the material itself which, in many cases, can
render on-site supply impractical when undertaking a structural timber frame
commission.
Structural Grade
Whilst we are sufficiently confident in our knowledge of the material to feel
happy that we are able to select timbers of a suitable nature for the kind of
construction we practice, there remains the issue of satisfying statutory bodies
(such as Building Control) that they are of a compliant structural grade. This
does not necessarily preclude local supply, but it may mean the timbers will
have to be transported quite some distance for grading and certification before
delivery to the workshop.
At Sessile Oak, we like to have the assurance that, should any timbers be milled
incorrectly or contain what we would consider unacceptable defects, the sawmill
(with whom we have developed a close working relationship over the years) can
send replacement timbers in sufficiently good time as to prevent significant delay
to a project and without the need for any further cost. We would hesitate to embark
on a project without this kind of assurance.
Sustainable Supply
It is also important to consider the issue of certification of sustainable supply
(such as through the FSC). Client sourced timber may be more sustainable both
environmentally and economically if an appropriate amount of new stock is planted
to replace it within a system of woodland management. This, though, requires both
the client's willingness and ability to carry out this sort of management in the
long term.
As we see it, that willingness and ability lies at the heart of the long term
practicality of local supply. In addition to bringing locally grown timber back
into rotation, there is a need to re-adopt the kind of management philosophies and
practices that created the quality of timber grown and used for centuries in this
country but which, in many cases, now have to be sourced from the continent. It
requires that we regain the willingness to commit to a long term regime of tending
with an understanding of the material as it grows over time in its natural or, at
least, semi-natural environment.
Whilst the solution may lie in the actions we take now, the results of those actions
will only become evident in our children's and grandchildren's time - there are no
large scale solutions from which we, in this generation, will benefit. Re-introducing
the culture of continuously tending woodlands for the supply of long-term quality
rather than short-term quantity requires us to re-examine our relationship with our
natural resources and what we want from them.
