There are regions valued deeply by those who know them, yet rarely introduced to the broader luxury market. Michigan's Upper Peninsula is one of those places. At 3870 Grand Oak, architectural detail, scale, and craftsmanship come together to create one of Iron Mountain's most distinguished private homes, positioned within one of the region's premier four-season destinations and nearly adjacent to Pine Mountain Ski and Golf Resort. A paved circular drive introduces the striking exterior, where custom wrought-iron detailing accents the porches and a 600-square-foot concrete veranda overlooking the lake, complete with integrated in-wall speakers. Professionally landscaped grounds include a newly constructed stairway and boardwalk leading to a circular lakeside fire pit and a 40-foot dock with a 300-square-foot dock porch. The property also adjoins 12 acres of uninhabited state land, adding a natural buffer and privacy. Inside, nearly 5,000 square feet of finished living space showcases Italian marble in the foyer and hallway, extensive custom maple cabinetry and millwork, and floor-to-ceiling transomed windows throughout. Three fireplaces, one wood-burning and two gas, anchor the main living spaces with warmth and architectural presence. The chef's kitchen is appointed with a Miele induction cooktop, Wolf built-in oven and microwave, custom maple cabinetry, and an inviting breakfast nook with distant views of the Pine Mountain ski jump. A mudroom with integrated custom cabinetry keeps daily life organized while staying true to the home's design. The west wing is dedicated to a private primary suite with lake-facing transomed windows, double French doors to the veranda, dual walk-in closets, custom built-ins, a Jacuzzi tub, spacious walk-in shower, and a private workout room. A studio or office with access to a crow's nest porch completes this wing. Upstairs, two additional bedrooms and a full bath provide comfortable, private accommodations for family or guests. The lower level adds exceptional flexibility wit
