Staircase, Metal Tread, and Wood Tread The kitchen is situated in a sunken basement, underneath the staircase’s walnuts steps. The same joiner who built the house’s timber elements built the white cabinetry which are finished in a 40% gloss lacquer. Silestone countertops and integrated appliances maintain the space’s simple lines. Additional storage is fitted under the staircase.
