Lumber prices are 9.6% higher than they were one year ago. …Impact of wood and lumber prices on the cost of a new home: In addition to narrowly defined framing lumber, products such as plywood, OSB, particleboard, fiberboard, shakes and shingles make up a considerable portion of the total materials (and cost) of a new home. Surveys conducted by Home Innovation Research Labs show that the average new single-family home uses more than 2,200 square feet of softwood plywood, and more than 6,800 of OSB, in addition to roughly 15,000 board feet of framing lumber. Softwood lumber is also an input into certain manufactured products used in residential construction — especially cabinets, windows, doors and trusses. …The bottom line is that changes in softwood lumber prices directly impact the price of a new home. This, along with rising wages for construction workers and higher interest rates, is one of the reasons the housing market is experiencing declining affordability.
