Michael Sowards, the ops manager from 2015, launches Winkler Woods furniture and cabinetry business to offer custom product to the booming development in Kaka’ako. We also established our millwork processes to accept many custom projects from all over the world! A few key projects we supplied materials for: the new International Marketplace Burial Room Wall exterior (custom-made Shou Sugi Ban), the interior wall at the Waiea Nobu in Kaka’ako with a VERY DIFFICULT finish process for their interior wall, again Shou Sugi Ban. We also made some Hawaiian Mango and Hawaiian Sugi dining tables for the extremely popular sushi restaurant, Sushi Murayama in the 808 Center. If you don’t like sushi, well, we think you will like the tables. Restaurant Nobu's wall paneling was another Sho Sugi Ban project completed by us. J


Winkler Woods becomes MUCH more “retail-friendly” getting more organized and easier for customers to come in and purchase many different exotic local hardwoods such as Lychee, Sugi, Ohai, Monkey Pod, Silver Oak, Robusta, Kamani, Milo, Kou, Japanese Tochi, Quilted and Figured Maple, Spruce, and a few others in lumber and natural edge slabs.
