Buying a "Once in a Lifetime" property centers on what you can't change: view, location, and surrounding woods and waters. This 10,000 square foot estate capitalizes all of that and more with awe-inspiring panoramas of Au Train & Grand Islands from protected Shelter Bay on Lake Superior's South shore in Alger County. Towering 50 feet above the largest body of freshwater on the planet are the South Wing residence & the North Wing office/gallery. Imagine your walk to work with sunrise painting your path over the 52' skywalk connecting the 2 structures. Currently home to SISU Cycles--custom bicycle frame builder--office/gallery space stands 3 floors tall. Built in 2010 with meticulous attention to detail from the floating stairs to the vintage Hope's Windows and loft office. Architectural drawings to finish the 4-story residence--make it 5-story with a 16x16 cupola--included in Associated Documents. Let possibilities flow with wide-angle windows and balconies on every level to capture Superior's moods by day, and Northern Lights by night. Plans call for total 7 bedrooms/ 7 baths. Until the project is finished, live on site in the guest house. Originally built in 1945 but totally remodeled in 2010, the 2 bedroom/2 bath cottage has a host of custom touches from Sandstone fireplace and updated open kitchen to double shower and jet tub. Plenty of space for toys & tools with 32x40 3-car garage as well as 8x10 & 12x26 sheds. Your own private 20x70 boat launch installed in 2021 adjoins 31x26 cement patio beneath the Sky Walk. Outdoor space (decks & balconies) in the South Wing adds up to over 1300 square feet. Truly live the best of all worlds--Great as well as Inland Lakes--because at the end of the driveway is 266 acre Deer Lake. Located between Munising and Marquette, this property is a year round Mecca for fishing as well as world-class hiking, biking, kayaking, skiing, ice climbing and snowmobiling. We are truly blessed with 5 Great Lakes but only ONE named Superior.
