Tanglewood Development's presence in Illinois is centered on a single community, Rolling Oaks in Sugar Grove. With 0 new construction listed against the current inventory, this is best approached as a resale market rather than an active builder price sheet — buyers here are shopping homes that have already been through at least one prior sale, not selecting from a builder's active floor plan lineup. Floor plans in Rolling Oaks include the Aspen, Birch, Cherry, Cherry 2, and Dogwood, giving the community a mix of layouts that still show up in today's resale inventory, currently priced from roughly $289,000 to $319,000. This is not an age-restricted or 55+ section, and there's no indication of ongoing development activity from Tanglewood in this pocket of the western suburbs. For buyers, that means evaluating these homes on their own merits — age of mechanicals, updates since original construction, and lot condition — rather than assuming builder warranties or new-construction HOA structures apply. Rolling Oaks remains a solid entry point for buyers targeting Sugar Grove specifically, particularly those comparing it against newer construction nearby and looking for established landscaping and a settled neighborhood feel rather than the wait and cost of building new.
