About the style
Coastal interiors distill the feel of a relaxed seaside home into a recognisable contemporary style that crystallised through the 1990s and 2000s in beach communities like the Hamptons, coastal Australia, and Mediterranean resorts. Built around light and air, it pairs crisp whites and soft sandy neutrals with the blues and aquas of sea and sky, layered with natural textures — weathered or painted wood, rattan, jute, linen, and rope. Nautical cues such as stripes, woven baskets, driftwood, and the occasional rope or shell detail appear without tipping into kitsch. Large windows, sheer fabrics, and pale floors maximise daylight, while slipcovered, casual furniture invites barefoot, low-maintenance living. The overall effect is breezy, calm, and unpretentious — an interior built to feel like a permanent holiday. Regional variants range from the polished Hamptons look to bright Mediterranean and laid-back Australian beach-house interpretations.
