A buyer comparing Geneva Lake villages this summer might expect Williams Bay to be the value play. It's smaller than Lake Geneva, quieter than Fontana, and its downtown sits an easy walk from the water. Instead, the numbers run the other way. As of early August 2026, Firstweber's listing data showed just 52 homes for sale in the village, with only one new listing added in the prior two weeks and an average of 116 days on market. Movoto's July 2026 figures put the median list price at $529,000, or $255 per square foot, with homes sitting a median of 148 days before selling, unchanged from the same month a year earlier. On the lakefront itself, LakePlace counted just seven active waterfront listings as of early May 2026, averaging $1.97 million and ranging from $935,000 to $3.8 million.
Small towns are supposed to have small inventories. But Williams Bay's tightness isn't just a function of population. Roughly 40 percent of its Geneva Lake shoreline sits in institutional zoning, not residential, not commercial, according to a village board member's comments in Crain's Chicago Business. That land was never part of the tradable housing stock to begin with, and understanding how it got that way, and what's changing about it right now, matters more to a comparison shopper than another median-price headline.
Land That Was Never Part of the Market
Camps, a shuttered college, and a former astronomical observatory make up much of that 40 percent. Williams Bay is home to Yerkes Observatory, the University of Chicago facility that housed the world's largest refracting telescope from 1897 until operations ceased in 2018. It's also home to what was, until December 2023, the George Williams College campus, run for decades by Aurora University. Several long-running lakeside camps hold additional acreage under the same institutional designation.
None of that land shows up in a comparison of median prices or days on market, because none of it has ever been available to buy. A village board member who owns the Harbor View Motel & Cabins put it plainly to Crain's: the highest value of any institutional site, once it's released, is commercial. That's the tension running underneath everything that's happened on this shoreline for the past twenty years.
A Shoreline That Has Moved Before
The current news around Williams Bay's largest institutional parcel isn't the first time this question has come up. It's worth seeing the pattern.
| Year | Parcel | What happened | Direction |
|---|---|---|---|
| 2006-2007 | Yerkes Observatory's lakefront acreage | University of Chicago sought to rezone from educational to residential for a resort and roughly 70 homes; the village refused and the developer withdrew | Blocked |
| 2018 | Frost Woods, part of the University of Chicago's original 77-acre Yerkes footprint | Sold off as residential building lots | Institutional to residential |
| 2020 | The remaining 48-acre Yerkes core | Transferred to the nonprofit Yerkes Future Foundation, which reopened the observatory for public tours and programming in 2022 | Institutional to nonprofit |
| Ongoing | A separate slice of the same original UChicago footprint | Purchased by Chicago executive Ann Drake, now being developed as a women's leadership center | Institutional to private institutional |
| 2023-2026 | The 137-acre former George Williams College campus | Sold to a hospitality developer and approved for a resort with a permanent conservation easement | Institutional to commercial |
The line that gets missed in most conversations about Williams Bay's scarcity is the 2018 Frost Woods sale. When the University of Chicago's 77-acre Yerkes-era footprint finally broke apart, one piece didn't become a museum or a preserve. It became ordinary residential lots. The precedent for institutional land quietly entering the housing market already exists in this village. It just didn't come with a public fight, because nobody was watching that closely at the time.
The Vote That Reopened the Question
Everyone is watching the George Williams College site. Aurora University ended instruction there in December 2023 and put the 137-acre campus, which fronts Geneva Lake along North Lakeshore Drive, up for sale. In April 2025, an affiliate of Topography Hospitality, a Chicago-based firm founded in 2021 by Liam Krehbiel, bought the property for $21 million, according to state property records reported by BizTimes.
The plan that emerged, called The Preserve at Williams Bay, cleared an initial concept vote from the Village Board in December 2024, then went through more than a year of revisions and hearings before a final version passed 5-2 in February 2026. The approved plan calls for a 68-key resort split between hotel rooms in a central lodge and detached one, two, and three-bedroom cottages, ten of which will be sold individually as condotels. It also includes multiple restaurants, a spa, racquet courts for tennis, platform tennis, and pickleball, a retreat center, and an outdoor amphitheater. Separately, roughly 90 acres of the property's former golf course, originally designed by James Naismith, will become a permanent conservation easement developed with the Geneva Lake Conservancy.
Krehbiel has said the company wants a light footprint on the water. In a statement reported in February 2026, he said Topography plans to keep just four boats for guest and club-member use and a small number of boat slips, with no marina-style buildout. Construction is set to begin once the company completes its capital raise, which Krehbiel said in December 2025 was nearly finished, with an opening targeted for 2027 if the timeline holds.
Why a Village Trustee Called It a Domino
Not everyone on the board saw this as a simple win. Susan Franzen, elected to the Village Board in April 2025, said she felt few residents knew about the project until it was already deep in the approval process, and that she initially opposed it before working to stay neutral through the debate. The same board member who owns the Harbor View Motel warned of a domino effect: once one institutional lakefront parcel converts to commercial use, every other camp and institutional landholder on the lake has a working example to point to.
That warning assumes the domino runs in one direction, toward hotels and resorts. The Frost Woods sale in 2018 is a reminder that it doesn't have to. Institutional land in Williams Bay has already moved toward nonprofit use, private institutional use, and ordinary residential lots. The Preserve is the first time it's moved toward commercial hospitality at this scale, but it isn't the first time the 40 percent has changed hands at all.
What This Actually Means If You're Comparing Williams Bay to Its Neighbors
For a buyer weighing Williams Bay against Fontana or Linn, the resort itself won't loosen the housing squeeze much. A 68-key hotel with a conservation easement doesn't add single-family homes or standard condos to the market. The ten condotel units are a genuine exception worth watching, since they'll be the first individually purchasable real estate carved out of this particular institutional footprint, but ten units against a backdrop of seven active lakefront listings won't move a median.
The more useful question is what happens to the rest of that 40 percent over time. The George Williams vote shows institutional land in Williams Bay can become commercial when a village board is willing to negotiate a conservation trade. The Frost Woods sale shows it can also become straightforward residential inventory when nobody's paying close attention. Both paths are live. Neither is guaranteed. A buyer treating Williams Bay's current scarcity as permanent is making the same assumption the 2006 developer made about the Yerkes site, that institutional zoning is a wall rather than a negotiation.
FAQ
Will The Preserve add homes to Williams Bay's housing supply? No, not in the conventional sense. The approved plan is a resort, not a subdivision. The ten condotel units are the only individually purchasable pieces, and they're hospitality units tied to the resort rather than standalone housing stock.
Does this change the zoning of other camps and institutional sites on the lake? Not directly. But a sitting board member has said publicly that this approval sets an example other institutional landholders could reference if they pursue commercial redevelopment of their own land.
When will construction actually start? As of Topography's December 2025 update, the company said it had nearly completed its capital raise and would begin construction once funding closed, with a 2027 opening as the current target if that timeline holds.
Williams Bay's shoreline math is more interesting than a median price suggests, and the parcels that could shift next matter as much as the ones already listed.
