In a London flat designed by MWAI, the design team benefited from a collaborative relationship with their client, one of the owners of UK-based millwork and joinery company INTERIOR-iD, who produced many of the custom elements. Here, a custom-built Corian countertop and sink merge when the sink basin is covered by a removable cutting board that can be kept in place for an added work surface, or removed for dedicated sink use. The cutout in the center allows water from the tap to flow straight through to the custom Corian drainer.
