Wisconsin's largest home is on the auction block

DOOR COUNTY -- Wisconsin's largest home is on the auction block! It's a 35,000 square foot cottage on a Bayside bluff in northern Door County -- named "Sur la Baie."

Stepping through the doors at Sur la Baie is like stepping back in time. The 43 rooms of the Ellison Bay mansion are ornately decorated, ready for grand entertaining.

Heiress Judith Blazer built the house in 1993 to mimic 19th century homes on the east coast. She sold it to the current owners in 2005.

"It's been on the market three years conventionally at which time the owners decided to take it to auction," HILCO Real Estate Auctions CEO said. 

One of the more traditional and eye-catching rooms: a stately two-story library, designed in the style of the Vanderbilt mansion. 

This mansion is not without modern amenities, including a home theater, a movie collection and a pool.  

The lavish home boasts three grand guest suites, 14 bathrooms and one astonishingly large master suite with two dressing rooms, two bathrooms, a sitting room and a fitness room---complete with elevator access.

"It's 5000 feet total, so it's larger than the average home in the U.S.," Fine said. 

The home features views of Green Bay with plenty of outdoor seating.

However, with nearly $140,000 in annual property taxes, Sur la Baie's costs are as breathtaking as the view. 

"We're expecting a lot of high profile interest in this from across the country. The Door County area is incredibly well-known," Fine said.

There's no minimum bid for the auction. But, the home previously sold for $18.5 million. Real estate agents expect with the markets how they are right now a buyer with enough cash could get a great deal on this priceless home. 

The auction is set for November 14th.

A beach house, guest chalet and 80-acre development site are also up for auction. Those can be bid either separately or with the mansion.
