design a modern kitchen interior featuring a white marble floor with minimal gray veining that sets a bright elegant foundation the central island should be a monolithic piece in pietra grey marble with striking veining and waterfall edges anchored by a black undermount sink and sleek fixture the backsplash should continue in the same pietra grey marble for a cohesive high end look base cabinets should be finished in a rich walnut or dark wood tone to introduce warmth and contrast upper cabinetry should remain minimal with only a third row of display cabinets at the top either with glass fronts or open shelving to maintain an airy and uncluttered feel over the island suspend modern pendant lights in warm toned metal or brass with soft white or patterned shades to add texture include stainless steel appliances fully integrated or flush with the cabinetry for a streamlined appearance the overall aesthetic should be clean and contemporary balancing natural materials with refined simplicity architecture
