The Darien, Connecticut estate owned by the descendants of baking powder tycoon William Zieglar is currently up for sale at $175million 

The 63-acre estate is its own private island with a main home, stables and several guest cottages

Great Island has been in the Zieglar family since the baking powder industrialist purchased it in 1902 

If the estate goes for anywhere close to its asking price, it will set a new record for most expensive residential property ever sold in the U.S. 

William Ziegler was born in 1843 in Beaver County, Pennsylvania and died in 1905 at the estate in Darien, Connecticut 

If Great Island sells for anywhere close to the $175million asking price, it will be the most expensive residential property every sold in the U.S.

The current record is held by a home in the nearby Hamptons which sold for $147million in 2014.  

Great Island is a 63-acre estate located on the Long Island Sound in Darien, Connecticut, about 50 miles from New York City, and is accessed by a man-made lang bridge.
