Saddle Farm, a 7.6-acre equestrian estate at 6191 S. County Line Road, went on the market for $10 million in August 2025. It sold for $6.1 million over the summer of 2026, according to Patch. The property had a 9,300-square-foot house with six bedrooms, a coach house, a lit riding area, a tennis court and walking paths. Cook County records put the house at about 80 years old, Patch reported in its April story on the listing. The buyer that emerged was Oakley Home Builders of Downers Grove, which wants to replace the estate with 16 homes.

That sale says a lot about how large parcels in Burr Ridge are valued right now. Only a small group of buyers wants a single 9,300-square-foot house on seven acres. A builder looks at the same ground and counts lots. How much the land is worth to that builder depends on one variable, which is how small the village will allow those lots to be. Over the past four months, Burr Ridge has started answering that question in public.

Why A $10 Million Estate Sold To A Builder

The closing price came in $3.9 million under the August 2025 asking price, about 39 percent less. That gap makes sense next to what Oakley plans to build. The developer expects homes in the new subdivision to start at $2.7 million. At that opening price, sixteen homes add up to more than $43 million in sales. Construction, infrastructure, carrying costs and approvals all come out of that figure, and none of those costs are public. Still, the arithmetic shows why the land was worth more as lots than as one estate.

That arithmetic only holds if the lots are approved. Oakley's plan needs half-acre lots in an area zoned for one-acre lots, Patch reported. The village's October 5 Plan Commission agenda lays out the request in detail:

• Rezoning from R-2A to R-3 single-family residential
• A special use for a planned unit development, or PUD, with deviations from the zoning and subdivision ordinances
• A variation dropping the minimum PUD site from 40 acres to 7.6 acres
• A variation dropping the minimum PUD lot width from 800 feet to 221 feet

Each item on that list feeds the per-lot math. If the commission sets a larger minimum lot size, the same 7.6 acres yields fewer homes, and the land is worth less to any builder. That makes the commission's most recent ruling on lot size the most important number for anyone who owns, or lives next to, a large Burr Ridge parcel.

The Line The Plan Commission Drew In August

That ruling came from 8101 County Line Road, which is zoned R-1. R-1 requires lots of at least five acres. The case took three steps over the summer:

1. June 1, 2026. The Plan Commission unanimously recommended denying a request to rezone the property from R-1 to R-3, which would have allowed lots of about half an acre. Two nearby homeowner associations, Bridle Path and Burr Oaks Glen South, opposed the smaller lots, Patch reported. Commissioners suggested lots of about two-thirds of an acre instead.
2. July 13, 2026. The Village Board sent the petition back to the Plan Commission to review an amended request.
3. August 3, 2026. The commission approved rezoning to R-2B by a 7-0 vote. R-2B requires a minimum lot area of 30,000 square feet and a minimum lot width of 125 feet. Lots that border County Line Road also fall under the County Line Road Overlay District, which requires at least 40,000 square feet and 130 feet of width. The petitioner's attorney told the commission that the neighboring HOAs no longer opposed the request.

Thirty thousand square feet is about 0.69 acre, which is the two-thirds of an acre the commissioners suggested in June. At the August meeting, village staff noted that Burr Ridge's Comprehensive Plan encourages lots of "30,000 square feet or larger." So over one summer, the commission rejected R-3 zoning and approved R-2B on the same parcel. R-2B carries a 30,000-square-foot minimum, and lots along County Line Road need at least 40,000 square feet. No subdivision layout was part of that approval.

Patch's October story on Saddle Hill described the earlier case as the Village Board rejecting half-acre lots in July. The village's own minutes show the denial came from the Plan Commission on June 1, and that the board's July action was the remand. The minutes are the record this post follows.

Two R-3 Requests In One Season

Both fall proposals ask for the zoning district the commission turned down in June.

McNaughton Development LLC is also asking to lower the minimum PUD lot width from 800 feet to 660.21 feet. The public notice set October 13 as the deadline for written comments. The home sizes, prices and lot dimensions in McNaughton's plan were not in the public materials reviewed for this post.

On the gross numbers alone, the two proposals differ. Saddle Hill puts 16 homes on 7.6 acres, about 0.48 acre of total site per home. McNaughton puts 21 homes on 16 acres, about 0.76 acre per home. Both figures include roads, open space and stormwater areas, so neither number is a lot size. They show how much land each plan spreads across its homes. The lot sizes themselves will come from the plans the commission reviews.

The outcome of the October 5 Saddle Hill hearing had not been confirmed when this post was written. The village's agenda page listed the meeting's agenda and packet but no minutes. Plan Commission actions in Burr Ridge are advisory either way. The Board of Trustees takes final action.

What The Development Proposal Asks The Village To Weigh

Oakley's application makes the case for its proposed density. In its application, the developer described Saddle Hill as low-density and said the density was among the lowest of any recent Burr Ridge residential approval, according to Patch. The site plan includes an outdoor fireplace, a gathering area, a pond and a pedestrian loop, and the subdivision would have no gate. Oakley estimates the homes would bring about $864,000 a year to local taxing bodies.

That pitch points to a mismatch in the local market. Owners leaving a large Burr Ridge estate often want a newer home with less land, and Saddle Hill proposes a $2.7 million starting price for that home. For someone selling an estate, that is a trade of land and upkeep for a newer house, not necessarily a step down in price. Whether that kind of product can be built in Burr Ridge depends on the same lot-size decision that determines what the seller's own acreage is worth.

The objections Patch reported are about how the project would work on the ground. Neighbors raised density, traffic and drainage. The president of the Burr Ridge Club, the subdivision across County Line Road, warned that cars turning left from facing entrances could collide. Several residents described backyard flooding they already have. A memo cited by Patch said a village engineer found that the submitted evidence "satisfactorily" showed runoff from Saddle Hill would not exceed the capacity of the village's storm sewers.

Reading A Large Parcel Before You Buy Near One

Each of these cases left a public record before its hearing. The Saddle Farm concept went to the Plan Commission as an "informal discussion" in April, before Oakley had filed an application and while the property was still under contract. The 8101 County Line request moved through a commission vote, a board remand and a second hearing over about nine weeks. McNaughton's notice was published about three weeks before its hearing.

A buyer looking at a home next to open acreage in Burr Ridge can learn a lot from these public records:

• Current zoning of the neighboring parcel. R-1 requires five-acre lots, and R-2B requires 30,000 square feet, which shows how much a parcel could legally be divided without a rezoning.
• The County Line Road Overlay. Lots that front County Line Road need at least 40,000 square feet even after a rezoning.
• Plan Commission agendas and packets. Informal discussions show up there before formal applications are filed.
• Who appeared at the hearing. In the 8101 case, the neighboring HOAs' positions were part of the record at both meetings.

Together, these records show which large parcels are already in front of the village and which zoning district the commission most recently approved.

A Few Distinct Questions

Does a rezoning approval mean homes are coming? Not by itself. At 8101 County Line Road, staff noted that no subdivision was proposed with the rezoning, and that any preliminary plat would go back to the Plan Commission for its own review.

Why does a PUD need a variation on site size? Burr Ridge's PUD rules start from a 40-acre minimum site. Both fall proposals sit on far less land, 7.6 acres and 16 acres, so each one asks for an exception before its site plan is even considered.

Who makes the final decision? The Plan Commission holds the hearing and makes a recommendation, and the Board of Trustees takes final action.
