Modern coastal interior design is a fresh take on traditional beach-inspired decor. It’s all about creating spaces that are light, airy, and calming, but with a sleek, contemporary twist. Gone are the overly thematic nautical motifs and kitschy seaside decor—instead, modern coastal design focuses on clean lines, natural textures, and a sophisticated palette of neutrals and ocean-inspired hues.

I first fell in love with modern coastal design after visiting a friend’s beach house. What struck me most was how effortlessly stylish it felt—light streaming through large windows, sleek furniture with subtle nods to the sea, and thoughtful textures that added warmth and depth. It inspired me to reimagine my own space, incorporating coastal charm without going overboard.

Whether you live by the water or simply want to bring the tranquility of the coast into your home, these key elements of modern coastal design will help you create a space that’s both chic and serene.
