20 Coastal Cottage Exterior Designs to Inspire Your Dream Beachside Home

The charm of a coastal cottage lies not just in its proximity to the ocean but in the way it embodies the relaxed and breezy essence of beachside living.
Whether you’re imagining sun-drenched afternoons on a porch or the soothing rhythm of waves as your backdrop, a beautifully designed coastal cottage can make those dreams a reality.
1. Classic Shiplap and Whitewash

Picture this: a cozy white cottage with horizontal shiplap siding, its surfaces kissed by the salt-laden breeze. The whitewashed aesthetic radiates simplicity and brightness, reflecting sunlight and creating a clean, inviting look. Pair this with navy blue shutters and a pop of color on the front door—a cheerful yellow or coral works beautifully.
Why it works:
- Shiplap siding is durable and quintessentially coastal.
- Whitewash creates a sense of space and light, perfect for seaside settings.
2. Weathered Cedar Shingles

There’s something timeless about weathered cedar shingles, their soft gray tones blending seamlessly with sandy beaches and rocky coastlines. This design works best when complemented with crisp white trim and a lush, overgrown garden for that lived-in charm.
Pro Tip:
Cedar shingles naturally weather over time, giving your home an authentic seaside look without additional maintenance.
3. Nantucket-Inspired Blue and Gray

For a touch of sophistication, consider a Nantucket-inspired palette of pale gray siding with accents of soft blue. This combination evokes the quiet elegance of New England coastal towns.
Key Features:
- Incorporate double-hung windows with grid patterns.

4. Bright and Breezy Pastels

Coastal cottages in soft pastels are like seashells scattered along the shore—each unique and full of character. Think pale pinks, mint greens, and sky blues. These hues evoke playfulness and are sure to catch the eye.
Make It Pop:
Contrast pastel siding with crisp white trim and light-colored roofing to keep the look cohesive.

Who says coastal has to be traditional? Modern designs with clean lines and neutral tones bring a fresh perspective. Picture smooth white stucco paired with large windows and natural wood accents.

No coastal cottage is complete without a wraparound porch. Imagine sipping lemonade as the sun dips below the horizon. Painted wooden railings, wide steps, and cozy furniture are all must-haves for this timeless feature.
Styling Tip:
Use outdoor rugs and wicker furniture to make the space inviting. Add planters with hardy coastal plants like lavender or sea grasses.
7. Thatched Roof Elegance

Channel a storybook vibe with a thatched roof cottage. While this design is more common in European coastal areas, it’s gaining popularity stateside for its romantic appeal.
Why It’s Unique:

Pair With:
