On certain projects that require that something special, I promote the use of British grown hardwoods.
Local to myself is an abundance of dealers in British grown timber, ranging from stock planks to beautiful, figured pieces.
Time and cost restraints on the majority of jobs require the use of more conventional sheet wood, veneer, and softwood. Today most of these products are FSC or PEFC-certified, ensuring sustainable practices from the timber’s origin location. Where possible, I always strive to use homegrown.
