Anyone willing to pay upward of $4 million for such a showpiece will, of course, want some certainty about his or her investment. The home sits on a waterfront lot that was just 2.79 feet above sea level, on a street that already floods during extreme tides and in a region where climate change will fuel sea-level rise by as much as 10 inches over 1992 levels by 2030.

Its very existence depends on the continued allure of the beaches, waterways and natural environment. Yet, by 2050, an estimated $15 billion to $36 billion of Florida’s coastal property will be threatened by sea-level rise, according to a report last year from the Risky Business Project, a Bloomberg Philanthropies effort that quantifies economic risks from climate change.
