Core Principles of Coastal Design

To truly capture the essence of coastal design, it’s important to understand the key design principles that make this style feel light, airy, and welcoming.

1. Light and Airy Color Palette

Coastal design often relies on a soft, muted color palette that reflects the colors of the beach and ocean. Think whites, soft grays, seafoam greens, sandy beiges, and sky blues.

These colors promote relaxation and make spaces feel open and breezy.

Bold accent colors like navy blue, coral, or sea glass can add pops of color without overwhelming the calm vibe.

2. Natural Materials and Textures

Natural materials such as wood, wicker, rattan, linen, and cotton are essential to coastal design.

These materials bring a sense of the outdoors in and emphasize the beauty of nature.

Light woods, distressed finishes, and woven textures create warmth while maintaining a relaxed and organic feel.

Consider adding jute rugs, sisal, and sea grass to enhance the natural texture.

3. Open, Uncluttered Spaces

Coastal design embraces open, airy spaces with minimal clutter. Rooms are typically bright, with plenty of natural light, and arranged to promote easy flow.

Furniture is often simple and functional, with an emphasis on comfort and relaxation. The goal is to create an environment that feels peaceful and effortless.

4. Nautical-Inspired Accents

Nautical elements such as rope, anchors, driftwood, and seashells can be used as accents to enhance the coastal aesthetic.

These accents should be kept subtle and tasteful, avoiding a kitschy or over-the-top nautical theme.
