Indianapolis-based Platinum Properties Management Co. LLC has submitted plans to the city of Westfield for a 720-acre development that would feature housing, shops, restaurants and recreational amenities in an area just off the city’s current northern boundaries.

Platinum Properties is proposing to build approximately 2,300 houses at Ironstone at Hortonville, which would be developed south of 214th Street, on the north and south sides of 206th Street, east of Freemont Moore Road and west of Oak Ridge Road.

The proposed project site is partially on agricultural land within the unincorporated community of Hortonville and bisected by Six Points Road, Horton Road and the Monon Trail.

Paul Rioux, owner of Platinum Properties, and Jon Dobosiewicz, a land-use professional with Carmel-based law firm Nelson & Frankenberger LLC, discussed the Ironstone project Thursday night in front of about 200 residents at a neighborhood meeting held at the Wyndham Westfield hotel.

“We’re trying to establish a village within a bigger community,” Rioux told the audience.

Dobosiewicz said Ironstone would consist of four areas: The Lakes, The Reserve and The Village, which would be limited to single-family houses, and the Horton Square Mixed Use block. The Ironstone name represents the iron of the Monon Railroad and the local limestone transported on the rail line.

According to a proposed site plan provided at Thursday’s neighborhood meeting, The Lakes would be built at the southwest corner of 206th Street and Six Points Road with houses priced from $350,000 to $700,000. The Lakes would have linear parks and a water feature called Carey Lake.

The Village and the Horton Square Mixed-Use block would at the center of the community. The Village would have rear-loaded single-family houses, along with town houses that would line the Monon Trail. Residences would be priced from $350,000 to $800,000.

Horton Square would have shops, restaurants and multifamily housing. A park called Foundry Park would feature pickleball and tennis courts, a 9-hole frisbee golf course, a waterfront amphitheater, a Monon Trail trailhead and an 8,000-square-foot clubhouse with a resort-style swimming pool.

The largest houses, including custom houses, would be at The Reserve on the east side of Ironstone, where home prices would range from $500,000 to $2.1 million.

The project site is not currently incorporated into the city of Westfield. Platinum Properties is seeking to rezone the site and have the property annexed into the city.

The entire community would have eight to 10 different housing types and 17 miles of trails. Platinum Properties would pay for improvements and widening projects on all of the roads bordering Ironstone. If the project receives approval from the Westfield City Council, construction would start next year and could take 10 to 15 years before completion.

“We’ll be planning this in sections,” Rioux said. “There will be dozens of sections over the next decade.”

He added that Platinum Properties worked with 12 different land owners to assemble property for Ironstone and began discussing the project with Westfield planning staff 14 months ago. Existing large residential developments nearby are Atwater, Chatham Hills, Monon Center and Osborne Trails.

Platinum Properties plans to donate 40 acres of land on the northwest corner of 206th Street and Six Points Road to Westfield Washington Schools. Westfield Fire Station 85 will be built on the southeast side of the intersection.

Platinum Properties, founded by Rioux in 1997, has developed more than 4,000 lots in 27 neighborhoods in Westfield.

Ironstone would not displace residents in Hortonville, an unincorporated community in Hamilton County that dates to the 19th century. The community is named for John B. Horton, who served as the area’s first postmaster.

Residents who asked questions wondered about the project’s impact on the surrounding area, property values, traffic and if existing homeowners would be affected by road-widening projects.

Ironstone is expected to be introduced to the Westfield City Council on Oct. 27. It would receive a public hearing on Nov. 3 at the Westfield Advisory Plan Commission’s meeting where residents can provide feedback. The Plan Commission would hold a workshop meeting in December and could provide a recommendation in February. The project could return to the City Council for a vote in March.
