Window Treatments for the Coastal Grandmillennial Style

Picture the morning light diffusing through sheer linen shades, casting a soft glow on a room where your grandmother’s floral china sits beside a collection of bleached seashells. A vintage rattan chair holds a cushion in faded blue gingham, while the walls—painted a whisper-light sea gray—frame a gallery of chinoiserie plates and watercolor botanicals. This is the essence of coastal grandmillennial style, where heirloom charm meets the relaxed elegance of life by the water.

Hunter Douglas Alustra® Woven Textures® Roller Shades near Arlington Heights, Illinois (IL)

It’s a design philosophy that feels curated and intentional, yet effortless. Designed without feeling too precious. The coastal grandmillennial style blends traditional elements with fresh coastal influences, creating spaces that feel simultaneously timeless and current. This appealing design approach combines classic patterns, vintage-inspired pieces, and breezy coastal colors to create collected and curated rooms.

The window treatments play a starring role. They’re the unsung heroes that frame your view, filter the light, and tie together the room. Ready to weave that same feeling of nostalgia and homeyness into your own space? Let’s explore three Hunter Douglas window treatments that pair wonderfully with coastal grandmillennial interiors.

Woven Coastal Window Treatments

Alustra® Woven Textures® Roller Shades capture the essence of coastal grandmillennial style with their natural textures and artisanal quality. These handcrafted window coverings feature materials made from natural, refined weaves, bringing organic elements indoors—a hallmark of coastal design.

These shades reference traditional craftsmanship while feeling completely current. The visible weaves and natural variations add visual interest and depth that mass-produced window coverings cannot match. These shades create a pleasing contrast between structured patterns and natural textures when paired with floral fabrics, classic furniture, and coastal accessories.

Available in a range of hues, from sandy beiges to deeper woods, shades from the Alustra Collection® can complement any coastal color palette.

For a proper grandmillennial approach, consider layering these woven shades beneath drapery panels in a classic pattern like stripes or toile—creating that coveted collected-over-time appearance.

Charming Grand Millennial Window Treatments

Vignette® Roman Shades offer a contemporary take on a traditional window covering, making them ideal for the coastal grandmillennial style. Their clean lines and structured folds bring order and sophistication to windows, while their soft fabric adds warmth and texture.

For a coastal grandmillennial look, consider these shades in textured neutrals or subtle patterns in a coastal blue, like chambray fabrics ort linen-look materials. Patterns like checks, gingham, or stripes work particularly well with this style.

Timeless Wood Blinds

Parkland® Wood Blinds bring architectural structure and traditional appeal to coastal grandmillennial interiors. These classic window treatments come in a variety of paint or wood stain tones to match any design.

The crisp horizontal lines of wood blinds provide a pleasing counterpoint to the patterns often found in grandmillennial spaces. Their substantial presence frames windows beautifully, creating a finished look that complements traditional moldings and millwork. Available in various slat sizes, these blinds can be scaled appropriately to your windows and room proportions.

For coastal settings, lighter wood finishes, whitewashed paint, or white-painted options capture that sun-bleached, seaside quality, while darker woods can anchor a space and reference antique furniture—another grandmillennial staple.
