LINN TOWNSHIP — If you ever needed proof that it remains a hyper-hot real estate market, check this out:

Glanworth Gardens, the luxurious $39.25 Geneva Lake Estate of the late Chicago investment Richard Driehaus has an offer just three weeks after it went on the market.

According to an online real estate listing, and confirmed by Crain’s Chicago Business, the estate was under contract as of Nov. 11.

The name of the potential buyer has not been revealed, nor is it known if the offer is above or below the asking price.

The property at 3505 Snake Road is being offered through Geneva Lakefront Realty and had been carefully restored by Driehaus, who died in March at age 78.

The asking price is reportedly a Lake Geneva record, and it stands as one of the highest in history in the Midwest.

The estate includes 40 acres of gardens and forest, 621+ feet of level frontage, and features a home with 14,145 square feet.

According to the description by listing agent David Curry, this legacy property occupies not only one of the finest lots on the best streets and features the highest grade architecture and finishes, it is an iconic property that is so respected because of both what it is and what it represents.

Driehaus lovingly oversaw the restoration of the estate over the years, and annually hosted a spectacular themed birthday party and fireworks show that was one of the most well known events on the lake.

He also was a generous philanthropist, supporting for many years the Circus World Museum in Baraboo and once bringing a display of circus train cars to downtown Lake Geneva.

He also donated the namesake Driehaus Family Fountain that graces the front of the Riviera Boathouse downtown.
