Granot Loma, a fancy-pants named beachfront estate on Lake Superior, hit the market this week at a staggering $40 million. The self-described "largest log cabin in the world," built over the course of four years and completed in 1923, this 26 thousand square foot mega mansion originally cost $5 million to build—nearly $70 million in 2015 dollars. The home's original owner, financier and bank president Louis G. Kaufman played a key role in the founding of General Motors and served on the automaker's board for over 20 years, giving this home a Detroit connection.

Granot Loma rests on a peninsula surrounded by Lake Superior, just north of Marquette. This is the ultimate Up North house. Though summer has come and gone, imagine Thanksgiving or Christmas here and you'll wish you had $40 million. The home is constructed of Oregon pine, cement and stone. The great room, a massive 60-foot-long space, has a huge stone fireplace with an 18 foot mantle. The vaulted ceilings are 24 feet and feature a large, carved chandelier. If you want a fireplace for every family member (immediate and shirt-tail), not to mention every last friend and pet, you're in luck—the house has 25 additional of them.

There are 23 bedrooms, 13 baths, and a spectacular kitchen the listing claims is modeled on the one at the White House kitchen. There's also a solarium, a card room and a game room where George Gershwin played for the Kaufman family on a Steinway Grand that comes with the property. The modern amenities are pretty swanky, too—there's a 3,000 gallon outdoor hot tub overlooking the lake and private harbor, complete with its own marina and boathouse which can house many freshwater offshore boats and keep the icky salt away!

The interiors are a weirdly appealing blend of expensive finishes and kitsch. There's a stone bath that has to be seen to be believed, complete with painting of Native American warrior, and there's a living room whose current decor scheme consists of every animal you can imagine as taxidermy. We counted a bear, a wolf and many, many things with antlers there.

If 23 bedrooms aren't enough, there's also a guest house with 4 apartments, not to mention servants' quarters, a root cellar and a tennis court designed by 1920s champ Bill Tilden. The house comes with over 5,000 acres of land, including a full trail system and nearly four miles of shoreline. And it can all be yours. For $40 million. If you have 30 roommates, or hit the Powerball, this is clearly the place. Jokes aside, this house is fabulous, and one of the rare Michigan lake mansions that has this kind of pedigree. It's grand old construction, built to last, and an amazing architectural treasure in its own right.

Too bad summer there is 10 days long and the water never gets much past 50 and sometimes 40 degrees EVER and its 200+ miles to closest city with a real grocery store or restaurant!! !!
Together with collaborators at the University of Colorado-Boulder and Environment Canada, LimnoTech scientists developed a map-based water temperature model for their 2014 forecast. The model was given the acronym “SLATE,” which stands for “Seasonal Lake Temperature Energetics” model.

The SLATE summer forecast predicted that 2014 surface waters above the deepest parts of Lake Superior would remain cold well into August – likely not exceeding 40 degrees Fahrenheit. Satellite data provided by collaborators at Michigan Tech Research Institute verified this prediction, while also showing that the lake was even colder in early August than what the SLATE model predicted; some parts of the lake were only 37 degrees on August 5, 2014

I would need a gps to find my way around inside that place

Sounds like the realtor needs to change the ad to reflect "Ice Skating at the Lake 10 months a year!"

I have never been to Michigan but I did think 5000 acres on the lake was rare........now I understand why....its in the middle of nowhere and the water is real cold.

Coming up on 100 years old and it looks fabulous. The craftsmanship from those days is unbelievable.

All the open cooling engine guys with crossovers would have open their engine tolerances past the "wore the fack out" specs if running 50W oil........ I read it on the internet so it has to be true.

AAAAAAAH its not that bad.15 min from marquette. I've seen snow as late as mid may as early as october. The 1st weekend in october this year I woke up to 4" snow, full ground cover. It wasnt very appealing looking at my fountain in the driveway with 4" of snow covering the bow.

I really like Marquette, best part is you are closer to Green Bay than Detroit so it's perfectly fine to be a Packers fan instead of the Lions....
That place is interesting, can't imagine what the heating bills and upkeep would cost.

plus maintaining the 5000 acres!

If the acreage is mostly forest its pretty easy to maintain. Even if its pasture, its pretty easy. My neighbor mows my yard for free. He makes hay and can sell what he doesn't use.
