Here is another amazing staircase that is designed and made by NK Woodworking based out of Seattle. The Project is “Curved Harmony” Staircase installed in 2013. The Staircase is made of White Oak, Walnut and Sapele. The stringers and handrails are made from Sapele lumber from East Teak Fine Hardwoods. The textures in the Sapele and really brought out in their amazing work.
