The Lake Ellyn home you've been waiting for! At 789 N Park Boulevard, beautifully maintained historic character meets more than 3,200 finished square feet, 4 bedrooms upstairs, a large fenced yard, and a location just steps from Lake Ellyn, downtown Glen Ellyn, Glenbard West, and Forest Glen. A proper foyer opens to the 22-foot front living room, where built-in bookcases, original millwork, a decorative fireplace, and beautiful natural light immediately set the tone. The formal dining room features original leaded-glass French doors and an arched built-in china cabinet, with enough flexibility to serve beautifully as a main-floor office or additional living space if desired. An adorable butler's pantry and dedicated coffee bar connect to the eat-in kitchen, featuring Thermador and JennAir appliances, generous storage, and a large sink overlooking the backyard. At the rear of the home, the expansive 23-foot family room opens through French doors directly to the brick paver patio and yard. A full bath, ample closet space, and attached-garage access complete the main level. Upstairs, all 4 bedrooms are located together alongside a full hall bath, while a staircase continues to the finished 3rd-floor bonus room, perfect for a kids' hangout, playroom, reading nook, home office, or additional lounge space. One of the home's most compelling opportunities is the potential to create a true primary ensuite without sacrificing any of the 3 secondary bedrooms. Conceptual plans available to review at the property illustrate how, if desired, the existing 2nd-floor footprint could be reworked to create a 2nd full bath directly adjacent to the primary bedroom. In many Lake Ellyn homes, accomplishing the same goal often requires a substantial addition or giving up an existing room, making this an especially valuable possibility. The finished basement adds recreation space, a separate laundry room, utility area, and substantial storage. Outside, the professionally landscaped approximately 70' x 149' lot is fully fenced and features mature plantings, a brick paver patio, and a generous stretch of usable lawn. A 1.5-car attached garage and long private driveway provide additional parking. The home was rehabbed in 2017, with the furnace replaced in 2026 and water heater in 2020.
