Thread: Pack lot

Not wanting to sound unconcerned about the problems trees face but can anyone tell me what sort of quantity of timber a "pack lot" generally is??? Would this generally be the quantity required to line or frame an average sized house or something? Also I was told by a timber retailer that it would be a mistake to buy sized softwood (Eg: 190x12) to convert to T&G lining myself because the mill not knowing the end use would tend not to care too much about the quality of the planing - is it usual to ask a mill to pick out only suitable timber? If not how much over the required quantity would you generally have to buy??
Thanks
