This is a true list. Nitty grittier of house building make this hard to do if you do not know the regime you are building in. We find our “best” as a balance of:
- House style and setting: beach, harbor, marsh, mountain, rural acreage or village.
- Legal clarity and ease of title verification.
- Buildability: zoning, setbacks, utilities, drainage, contractors and material supply.
- Travel practicality: drive, bridge or short-ferry access rather than multi-leg international logistics.
- Year-round livability: hospitals, groceries, airport access and community.
- Weather and insurance realities.

| Island | Country / region | Dream-house style | Practical advantage | Watch-outs |
|---|---|---|---|---|
| Longboat Key | Florida, USA | Gulf-front contemporary home, bay house or canal-side retreat | Bridge-connected, close to Sarasota, with an established construction ecosystem, major services and a local planning department | Hurricane exposure, flood elevation, insurance cost and tight zoning and design rules |
| Amelia Island | Florida, USA | Beach cottage, live-oak estate or classic Southern coastal home | Drive access, Jacksonville airport and hospitals nearby, historic Fernandina Beach and a four-season community | Flood zones, dunes and historic-district rules can shape what you build |
| Sanibel | Florida, USA | Low-rise beach house focused on nature and indoor-outdoor living | Causeway access, established island services and an exceptional wildlife setting | Very serious hurricane, flood, rebuilding and insurance considerations |
| North Captiva Island | Florida, USA | Off-grid-leaning beach house or private family compound | Extraordinary seclusion while remaining in the U.S.; boat access protects the castaway quality | No road connection, construction freight and labour logistics, generators, water systems and storm resilience |
| Bald Head Island | North Carolina, USA | Car-free beach house, maritime-forest retreat or family compound | Ferry access from Southport, planned-community structure, privacy and a credible second-home culture | Ferry dependence, wind and hurricane exposure, plus island service costs |
| Isle of Wight | England | Victorian seaside renovation, rural stone cottage or modern coastal house | Ferry-linked but close to southern England services, with a strong year-round community and established planning system | Conservation, landscape and coastal planning restrictions, plus ferry logistics |
| Whidbey Island | Washington, USA | Pacific Northwest modern home, forest retreat or waterfront cabin | Bridge or ferry access, close enough to Seattle for regular use, with established U.S. utilities and contractors | Rain, septic and shoreline rules, plus ferry queues in peak periods |
| Mallorca | Spain, Balearic Islands | Stone finca, courtyard house or contemporary sea-view villa | Mature architecture, strong airport access, a deep pool of builders and suppliers, and full-service living | Strict rural and coastal planning, water limits and high prices in prime districts |
| Madeira | Portugal | Dramatic ocean-view modern home or terraced garden house | Reliable urban services around Funchal, an international airport and an EU legal framework | Steep sites, road access, drainage, retaining walls and engineering costs |
| Grand Cayman | Cayman Islands, British Overseas Territory | Beach villa, canal home or hurricane-resilient modern compound | English-speaking, with an established land registry and a transparent foreign-ownership framework | High land and construction prices, salt-air maintenance and hurricane insurance |
