A narrow section beside a window can provide useful cupboard space without covering the glazed opening. Here, a tall grey cabinet stands between the window and the basin area, with several doors stacked vertically. The window sill remains visible beside it, and the cabinet rises well above the worktop.
Using height gives this corner a different role from the basin furniture. Closed compartments can accommodate bathroom supplies while leaving the nearby sill as a separate surface. Consider how the cabinet meets the window reveal and worktop, so the extra storage feels fitted to the room rather than added across the light.
