Japanese Larch and its Innovative Applications in Construction 2014
The Wales Forest Business Partnership (WFBP) have surveyed 55 Japanese larch sites across Wales and estimate that 4.9 metre sawlogs make up 24% of the total crop of 1.89 million cubic metres. This could produce around 1 million cubic metres of sawnwood or 50,000 timber framed and timber clad three bedroomed houses. Add in projected volumes of sawnwood from The Marches and these figures increase to anything between 68,750 and 76,725 houses.
