# 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
1. Blue-and-white palette — from navy to soft sea-glass
2. Natural linen, cotton, and jute textiles
3. Shiplap and tongue-and-groove wall paneling
4. Painted white woodwork — detailed millwork, coffered ceilings
5. Striped fabric (ticking, awning stripe) on upholstery and cushions
6. Weathered or whitewashed wood surfaces
7. Wicker and rattan furniture (indoor and covered outdoor)
8. Coastal artifacts — driftwood, sea glass, rope, shells (used sparingly in quality versions)
9. Oversized windows maximizing sea or garden views
10. French doors opening to covered verandahs
11. Formal dining room for entertaining, casual kitchen for everyday
12. 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.
