A North Shore estate with deep roots in Midwestern history has returned to the market with a price adjustment. It presents the opportunity to own a pastoral retreat that feels like a slice of rural Britain rather than a home just 40 minutes from the Windy City.

The Tudor-style residence at 499 West Old Mill Road in Lake Forest is listed for $4.7 million and sits on nearly 10 fully fenced acres bordering a restored prairie reserve originally created by landscape architect Jens Jensen, best known for his work on historic public gardens throughout Chicago.

Long before these reimagined gardens began blooming, the 1935 home was part of a much larger agricultural estate tied to one of Chicago’s early business leaders, George Rasmussen, founder and chairman of the National Tea Company.

Known historically as Elmwood Farm, the property was a working agricultural estate, with dairy cattle that made headlines for record-breaking production.

“This property is truly magical,” says listing agent Jean Anderson from Sotheby’s International Realty. “Driving through the gates, you immediately feel the beauty of the setting.”

Over time, portions of the original estate were subdivided, but the remaining acreage has preserved the estate’s character, with the grounds themselves being among its most enchanting features. 

A butterfly garden, organic potager, orchard, vineyard, and stocked water lily pond create a layered landscape, while beehives that produce honey and a fully organic vegetable garden continue the home’s legacy of land stewardship. 

That sense of retreat continues inside the nearly 6,000-square-foot home, where original details have been preserved and thoughtfully enhanced. Walnut paneling, intricate ceiling moldings, and leaded glass windows evoke the elegance of the home’s early years.

The formal living room features a soaring 10-foot ceiling, while the dining room’s fireplace and classic architectural details create a dramatic backdrop for seasonal gatherings. A cypress-paneled library offers sweeping landscape views, and a kitchen crafted by Altounian Builders connects to a bright family room and outdoor entertaining spaces.

Outdoors, the property is anchored by a pool and spa, fireplace, and pergola dining terrace with a full kitchen.

Anderson notes that the current owner’s professional background adds another layer of distinction.

“Because the home is owned by Frank Mariani, whose firm is known for exceptional landscape design and build work, it’s no surprise that every inch of the grounds has been beautifully maintained,” she says. 

With nearly 10 acres, the property also allows for horses and offers potential subdivision opportunities, features that make it equally appealing as a full-time residence or weekend escape.

“This would make a wonderful getaway from the city,” Anderson adds. “It’s the perfect property for someone wanting peace and privacy.”
