170 N Savanna Court: $4.1M Lake Forest Pool Estate

Date of Publishing: November 14, 2026

The pergola beside the swimming pool at this Lake Forest estate has a feature that does not announce itself from the terrace: a basement. Above it, an outdoor fireplace, heaters and a sound system equip a covered lounge. Below, a large unfinished space offers storage or the possibility of future finished space, according to the listing. It is one particularly unexpected detail in a backyard that the owners have spent $1 million transforming.

Offered for $4,100,000, 170 N Savanna Court occupies 1.38 acres overlooking the Middlefork Savanna Forest Preserve. Ann Lyon of @properties Christie’s International Real Estate represents the property. Built in 2005 and subsequently updated, the French Provincial residence is marketed with 7,508 square feet, five bedrooms, five full bathrooms and three half bathrooms, together with an extensively finished lower level and a heated four-car garage.

A $1 Million Backyard With an Unexpected Lower Level

The outdoor design, credited in the listing to Arrow Land + Structures and Greengard, puts several distinct gathering areas around a 20-by-50-foot swimming pool built by Downes Pools. Deck jets animate the water, and an automatic cover is among the pool’s practical features. Bluestone terraces, garden walls and an outdoor kitchen give the setting the structure of a series of rooms rather than a single patio.

In Lyon’s published listing materials, the pergola is described as having “a huge basement for storage or future finished space.” The wording matters: the space is presented as an opportunity, rather than an already completed guest residence. Above ground, the pergola’s fireplace and heating elements extend its usefulness beyond the warmest afternoons. Native planting, gardens and landscape lighting connect it to the larger property.

The preserve supplies a wider backdrop to the private grounds, with nearby walking and cycling trails adding another way to enjoy the setting. From the rear elevation, the pool and terraces form an orderly foreground before the lawn opens toward the surrounding landscape. The result is a home whose outdoor investment is experienced from many of its principal rooms, as well as from the water’s edge.

A Primary Suite With a Balcony Over the Grounds

The primary suite extends that relationship with the grounds. A separate sitting room, fireplace, coffee station and balcony create several places to spend time away from the main living floor. Two professionally designed walk-in closets accompany a bathroom with a soaking tub, steam shower and dual vanities. Three additional second-floor bedrooms each have an en suite bathroom, and laundry is also on that level.
