Experience modern luxury in this stunning 4-bedroom, 3-bath retreat in sought-after Dune Acres--where urban industrial design meets the natural beauty of the Indiana Dunes. Set on a secluded .95-acre wooded lot adjacent to the National Park, this architecturally significant home offers a rare connection to nature just moments from beach access. A dramatic 10x10 entry with heated limestone floors and expansive glass creates an immediate sense of light and openness. The step-down living room serves as the centerpiece of the home, anchored by a gas-start fireplace and framed by floor-to-ceiling windows that bring the surrounding dunes landscape indoors. The main level features soaring 13-foot ceilings, radiant heated limestone floors, and an open flow between the living, dining, and kitchen spaces. The updated kitchen is equipped with a professional-grade Thermador 6-burner range, under-counter Sub Zero refrigerator drawers and newer book-matched white oak cabinets with a natural stain. A flexible guest bedroom (currently used as a den), laundry room and a half bath complete this level. The private, south-facing primary suite offers direct outdoor access and a spa-like bath with a custom glass shower and travertine vanity. Designed for indoor-outdoor living, the home features a screened porch tucked behind the fireplace and a wraparound deck with sleek stainless steel railings. A striking floating staircase leads to the second level with two additional bedrooms, a full bath, and a large studio or office space with potential for a rooftop observation deck. The lower level includes a landing with a prep kitchen, storage, and access to the oversized two-car garage. An adjacent .85-acre lot is also available for purchase.
