I have found a source for recycled rough sawn ,d.f. 10X12 timbers in 40 foot lengths. I do not as of now have a specific design but wish to build a small timber frame home/cabin. Maybe 24X40? I have indoor storage available. Would these timbers be a good resource to have stashed for future project? I don't want to buy,store and then not be able to use. Opinions? Also the seller is asking $1 per b.f. Is that reasonable? Thanks for any input.
