Picture a regular window and you’re bound to think of a rectangle. But sometimes the right window for your space doesn’t require any right angles at all: porthole windows have come full circle as a means for whimsical and shapely facades, and the architectural feature is even popping up across interior walls.
And while they're most common on exterior walls, specifically for bathroom or kitchen window ideas, installing a porthole as an interior window creates soft connections between rooms while flowing light from one space to the next – all with a bit of charm. ‘Internal windows can be tricky to get right, and a porthole window is a more playful way to connect two spaces than a rectilinear one,’ says Tom Surman, director at London’s Surman Weston.
