It is a Ranch-style dwelling with Prairie style influences, veneered in Bedford limestone.","why_significant":"The nomination presents the house as a well-preserved, early local example of a Ranch style home with Prairie design influences, built when few such houses existed in Mattoon. It also reflects the vision of Richard Roytek, a local businessman who planned the house and designed the landscaping. The house retains a high percentage of its original design, materials and interior finishes.","narrative":"This house at 3420 Richmond Avenue on the western edge of Mattoon, Illinois, was completed in 1950 for Richard Roytek, a local businessman who later managed the city's Dairy Queen franchises. After seeing a Ranch style home in Texas in 1948, Roytek obtained its floor plan and photographs and hired local contractor Harry Kabbes to build a version in Mattoon. No architect was consulted. The cost was $19,000. The long, asymmetrical house has a cross-hipped roof, wide eaves, ribbon and wrap-around windows, and walls veneered in quarry-cut Bedford limestone, combining Ranch planning with Prairie style features. Inside, it keeps much of its original oak framing, birch and maple woodwork, and plan over a full basement. Roytek also designed the surrounding landscape, planting trees on a lot that had none. His family lived there from 1950 to 1994. Alterations include replaced windows, some overlaid floors and an opened kitchen wall.","period_of_significance":"1950-1960","architect_builder":"Built by local contractor Harry Kabbes; no architect or engineer was consulted.
