Coastal interior design translates the beach house into any home: salt-bleached neutrals, breezy linen, horizon blues, and light kept as unobstructed as possible. Done right it is restraint, not theme, no anchors on the wall, just the colors and textures of shoreline light. Airy fabrics and whitewashed wood do the storytelling.
It grew from the vernacular of New England and Hamptons beach cottages, where practical, light, sand-tolerant interiors became a style in their own right. Build on foam white and sand, then commit to blue in two depths: sky and navy, with driftwood tan as the bridge. Treat the signature elements below as a checklist: a room needs most of them, in restrained doses, before it reads as coastal rather than themed.
Coastal works across the whole house, but it pays off fastest in the living room: slipcovers and jute make an easy, sandy-feet-proof social hub.
