|Island Estates' Commercial Division is now constructing a three-building complex at the intersection of Route 25A and Mt Sinai-Coram Road. The Commons will include a 10,000 SF. day care center, a full service bank with Drive-thru capability, and a 5,600 SF. medical and professional office building. The Commons will be managed by Island Estates to insure that it will always be an attractive part of the Mt. Sinai Community.
