On October 18th, BC Minister Steve Thomson had a warm sunny fall day to lead a key industry delegation of 30 forestry experts to view a large wood structure being constructed in Shiroi City, Chiba Prefecture. The new elderly care project named “Nursing Home Ansuriru” is a two-storey 2×4 fireproof structure located approximately 80 km northeast of Tokyo. The nursing home will have 90 units for full time senior residents and another 10 units for short stay occupants

While touring the construction site, Minister Thomson took time to thank the owner of the building for choosing to construct this project using sustainable Canadian SPF dimensions lumber products and the platform frame construction method. Senior representatives of the construction and design team for this project were also on hand to welcome the delegation and speak with them at the site.
