A secluded Kiawah Island estate has hit the market for $29 million, which ties a mark set by a previous unsold listing for the island's loftiest asking price.

The home is on Blue Heron Pond Road on a small stretch of wooded high ground that extends out into marshland along the Stono River. With 15,000 square feet indoors and 11.7 acres, the gray brick home is the island's largest in square footage and acreage.

The property also has 5,000 square feet of outdoor living space between its porches, balconies and patio space surrounding the infinity pool. It also has a deepwater dock, five-car garage and guest house, according to description posted on Luxist.com, which reported the $29 million asking price last week.

The property owner listed on the deed is Buttonwood Trust, which traces back to former Goldman Sachs partner Jeffrey Weingarten and wife Susan. A sale anywhere near that asking price would set a record for the resort island, which saw its priciest transaction earlier this year. For $14 million, a company managed by Chicago-based beverage distributor Jude Reyes bought a 9,900-square-foot oceanfront home on Ballybunion Drive. That sale included the furnishings.

The Blue Heron Pond property isn't the first on Kiawah to ask $29 million. Five years ago, billionaire couple Bob and Janice McNair also put their oceanfront Flyway Drive home on the market for that amount but later took the property off the market.

Kiawah Island Real Estate is marketing the Buttonwood Trust property, but the firm is not publicizing the asking price on its website.
