Set in a ribbed-vaulted stone chamber, this Gothic laundry pairs emerald marble worktops and a monolithic island with deep plum cabinetry detailed with arched, mesh-front doors. Leaded lancet windows wash the limestone walls in violet and green, intensifying the moody palette. A U-shaped run with a white undermount sink and brass tap, terracotta floor, and a chain-hung drying rack create a functional workspace with cathedral-like drama.
