Coastal interior design style draws inspiration from the serene and breezy ambience of the beach. It incorporates natural light, soft colour palettes dominated by whites, blues, and neutrals, and materials such as light wood, rattan, and linen. The aesthetic often features nautical elements like shells, ropes, and sea-inspired artwork, creating a relaxed and airy atmosphere. Furniture pieces are typically casual and comfortable, promoting an inviting and tranquil environment that mirrors the laid-back feel of coastal living.
