Coastal / Hamptons Interior Design

Philosophy

Relaxed luxury. The tension between Atlantic or Pacific serenity and the confident ease of old wealth. Coastal design invites the ocean inside — its color, light, texture, and sound — without replicating a souvenir shop. Hamptons specifically adds architectural gravitas: cedar shingle exteriors, millwork heritage, and the muted palette of a sea-glass morning. Australian coastal adds sun-soaked informality and Queenslander timber tradition. Both share the aspiration: that the interior feels like a deep breath of clean salt air.

Core Characteristics

Blue-and-white palette — from navy to soft sea-glass
Natural linen, cotton, and jute textiles
Shiplap and tongue-and-groove wall paneling
Painted white woodwork — detailed millwork, coffered ceilings
Striped fabric (ticking, awning stripe) on upholstery and cushions
Weathered or whitewashed wood surfaces
Wicker and rattan furniture (indoor and covered outdoor)
Coastal artifacts — driftwood, sea glass, rope, shells (used sparingly in quality versions)
Oversized windows maximizing sea or garden views
French doors opening to covered verandahs
Formal dining room for entertaining, casual kitchen for everyday
Chandeliers made of bleached antlers, rope, or painted iron

Regional Variations

American Hamptons

Old money understated luxury; Long Island beach village aesthetic; cedar shingles; formal yet relaxed; Benjamin Moore White Dove as the standard white; millwork density is a quality marker.

Australian Coastal

Sun-soaked informality; indoor-outdoor life; Queenslander timber heritage; lighter, more casual; eucalyptus green in palette; less millwork formality, more bare timber natural finish; weatherboard and fibro cement cladding.

Hamptons Architecture Deep Dive

Exterior Markers

Cedar shingle siding — weathers naturally from honey to silver-grey over 5–10 years; the defining exterior material
White trim — Benjamin Moore White Dove OC-17 or Simply White OC-17 as standard
Black shutters — louvered, painted black, flanking every window
Wraparound porch — covered, with white columns, ceiling painted "haint blue" (pale blue-green)
Dormer windows — indicating sleeping rooms above; adds vertical rhythm
Cupola — optional roof ornament; traditional nautical reference

Interior Millwork Hierarchy

Crown molding — minimum 10cm; dentil detail in grander rooms
Wainscoting / chair rail — paneled lower wall, typically 90cm height
Coffered ceiling — grid of recessed panels; dining and living rooms
Built-in window seat — with lift-up storage, cushion in ticking stripe
Built-in bookcase flanking fireplace — symmetrical, painted white, glass-front upper cabinets

Colour System: Blue Hierarchy

The Hamptons palette operates on a blue gradient from deepest (accent) to palest (dominant):

Depth	Color	Hex	Application
Darkest	Navy	`#1A3A5C`	Upholstery stripes, throw pillows
Deep	Indigo	`#2A3D6A`	Artwork, occasional chair
Mid	Weathered Blue	`#7A9EB5`	Feature wall, shutters
Light	Sea Glass	`#7ABCB5`	Tile accent, glassware
Palest	Sky Wash	`#C8DCE8`	Secondary wall tone

Everything else is white, cream, or natural fiber. The blues punctuate; they never dominate.
