Living in Chatham Square

Chatham Square is the neighborhood I show buyers who want a Plainfield address with Oswego schools — a combination that exists only in the village’s far-north pocket near 127th Street and Heggs Road, where District 308 (Oswego) serves the community through Grande Park Elementary, Murphy Junior High, and Oswego East High School. For families targeting 308 without leaving Plainfield’s amenities and commute, this pocket is the answer, and Chatham Square is its anchor.

The community was built in two distinct eras, and it matters when you’re comparing homes: Gladstone Builders delivered semi-custom homes from the mid-2000s, then M/I Homes returned around 2019 with its Classic Series and built through 2023, when the community sold out. The result is streets where finish levels, architecture, and age vary meaningfully — a 2006 Gladstone semi-custom and a 2022 M/I production home are different products at similar prices. Homes run from about 1,850 to 4,200 square feet on lots averaging just over a quarter acre, with a townhome section adding an attached option.

Recent single-family sales ran from $545,000 to $705,000 — solidly in Plainfield’s move-up tier — with townhomes trading lower. HOA fees are modest for single-family (aggregator sources suggest an annual master fee around the mid-$400s; townhomes pay more, monthly), covering the parks, trails, and ponds that thread the community. The location trades downtown-Plainfield proximity for north-side convenience: 127th Street runs straight to Route 59’s retail, and Naperville is as close as it gets from a Plainfield address.

Chatham Square FAQs

What schools serve Chatham Square?
Oswego District 308 — Grande Park Elementary, Murphy Junior High, and Oswego East High School per MLS-fed sources — not Plainfield 202, despite the Plainfield address. Verify the current assignment for any specific address with District 308.
How much do Chatham Square homes cost?
Recent single-family sales ran $545,000–$705,000, with M/I’s newer resales at the entry of that band and the larger Gladstone semi-customs at the top. Townhomes trade lower. Call or text Kealan at 630-381-4995 for current availability.
Is Chatham Square still being built?
No — M/I Homes sold out the final phase around 2023, so everything trades as resale now. Buyers who wanted new here compete for the near-new M/I homes instead.
What’s the difference between the two builder eras?
Gladstone (mid-2000s) built semi-customs — bigger variety, larger top-end footprints, now entering second mechanical cycles. M/I (2019–2023) built its Classic Series — modern plans and newer everything. Similar prices, different products; we walk buyers through both.
What are the HOA fees?
Modest for single-family — aggregator sources suggest an annual master fee around the mid-$400s — with the townhome section billed monthly at a higher rate for exterior coverage. MLS-fed figures vary; we confirm exact numbers on every deal.
Why choose Chatham Square over Bronk Farm nearby?
Schools and product: Chatham Square is the 308-schools option with larger resale footprints; Bronk Farm is new-construction D202 territory with the clubhouse-and-pool campus. Same corridor, different answers — we tour buyers through both in one trip.
