Northeast Florida, and it's pristine coastline are experiencing a renaissance of new residential real estate development (since it first began in the early 2000's).
Tearing down older homes and mansions to build new luxury/state of the art mansions has engulfed the both Duval and Saint Johns counties. The tear-downs and new development are occurring primarily in the oceanfront (or close by) and the coastline of the St. Johns river.
This represents a shift in wealth and desirability of high net worth buyers and their desire to live in the less commercialized areas of Northeast Florida and the beauty of living in a highly desirable area of the state's coastline.
On the other hand, it is a little saddening to witness some of the pre war oceanfront mansions (mostly built in the 30's), being replaced by the typical large scale zero lot line homes that meet the standards of today's demands and taste.
One thing is for sure, change is inevitable, and adapting to change is the key to growth. The greater Jacksonville Beaches (including Jacksonville Beach, Neptune Beach Atlantic Beach and Ponte Vedra Beach) are all experiencing a rebirth and age of development that is needed to continue the growth and expansion of the Greater Jacksonville area.
