Just a short boat ride from New Rochelle, Columbia Island offers private island living minutes from Manhattan. The five-acre property features a radio tower that has been converted into a 5,625-square-foot estate. Its interior includes four bedrooms and boasts industrial vibes with a stainless steel kitchen, exposed ceilings, and polished concrete floor, while bare white walls give living spaces a gallery aesthetic. A lower level with exposed brick walls provides a flex space that can be transformed into a studio, bar, or media room. For added space, the neighboring Pea Island offers five additional acres for development opportunities. Bidding has begun, and the property is being auctioned with no reserve until October 18, 2023.
