A Naperville developer wants to build 25 luxury townhomes priced up to $1.45 million on a former warehouse site at Spring Avenue and Mill Street, near downtown shops and the Metra station.

Richard Kramer of Kramer Homes will bring the project, called Ostara, before the city's Planning and Zoning Commission on Wednesday, June 17. The three-story units would range from 2,900 to 3,400 square feet, each with three bedrooms, four bathrooms, a two-car garage, and a second-floor balcony. Prices start at $1.37 million.

The 2.3-acre site previously held a 30,000-square-foot warehouse and three single-family homes, all demolished in 2025. Kramer, who has built hundreds of homes in Naperville including in the White Eagle community, once operated his business out of that warehouse. He lives near the property.

The project has already been revised once. An earlier 26-unit plan required a density variance, but residents raised concerns in January 2026. Kramer redrew the layout to face townhomes toward the streets, swapped flat roofs for gabled roofs, and added decorative fencing and interior sidewalks. The current 25-unit plan no longer needs a density variance.

"He went back to the drawing board and worked carefully through the feedback point by point," said Jimmy Calvo, attorney for the project. "The result was a substantial reworking of the project."

Kramer still needs two approvals: a rear yard setback variance for lots closest to the Metra BNSF tracks to the north, reducing the standard 25-foot setback to as little as 12 feet, and a conditional use permit allowing single-family attached dwellings. Calvo told the Naperville Sun the reduced setbacks won't affect neighbors because the northern boundary abuts the railroad, not other homes.

A homeowners association would handle exterior maintenance, landscaping, and snow removal.

The proposal follows other recent residential approvals near downtown. The city council approved a six-unit development at 222 S. Mill St. in March 2026 and 11 rowhomes at Benton Avenue and Main Street in February 2026.

The Planning and Zoning Commission hearing is open to the public on June 17. No construction timeline has been announced.
