United Development in Illinois
United Development built homes across the Chicago suburbs during past development cycles, and today its Illinois communities function almost entirely as resale markets rather than active new-construction sites. Buyers browsing this builder's footprint will find established subdivisions spread across Algonquin, Aurora, Lisle, Palatine, Tinley Park, and Winfield. In the northwest suburbs, Cinnamon Creek, Eagle Ridge, High Hill Farms ($355,000–$534,700), and Spring Creek Farms ($390,000) are all found in Algonquin, while Butterfield ($349,500–$374,900) and Springlake ($219,900–$260,000) anchor the builder's presence in Aurora. Farther east, Forest Knoll in Palatine ($349,000–$349,900), Bristol Park in Tinley Park ($370,000), and Timber Ridge in Winfield round out the picture, with Green Trails in Lisle standing out for its range, spanning $249,900 to $949,000 across a mix of home sizes and updates. Shopping these neighborhoods means shopping resale: mature trees and landscaping, no builder warranty or new-construction HOA fees, and pricing that reflects each home's age, condition, and past updates rather than a current price sheet.
