Bordered in brick with bluestone pavers, stucco walls, and a fountain, this private oasis is reminiscent of Charleston's finest courtyards.

The neighborhood offers walking trails, parks, lakes, a boat ramp, and the opportunity to join the private I'On Club (with swimming, tennis, dining and pickleball). An opportunity for luxurious living in the heart of Mount Pleasant!
