313 Forest Avenue Historic Frank Lloyd Wright Masterpiece in the Heart of Oak Park Nestled in the heart of Oak Park's renowned Frank Lloyd Wright Historic District, the Hills House is a rare opportunity to own a meticulously preserved and thoughtfully updated architectural gem. Designed by Frank Lloyd Wright and completed in 1906, this exceptional residence combines iconic Prairie School design with timeless livability, making it one of the most comfortable and functional Wright homes in the area. Set on two expansive lots (approx. 100' x 150'), the home offers over 6, 350 sq ft of living space with 6 bedrooms, 4 full baths and one half bath. The final construction drawings-strongly influenced by Wright's 1905 visit to Kyoto, Japan-reflect his deep appreciation for Japanese art and architecture, visible in the harmony of form, material, and space throughout the home. The current owners, since 2001, have carried out an extensive and faithful restoration, bringing the home back to its original glory. Exterior restorations include the rebuilding of the garden pavilion and a section of Wright's pergola, the addition of an architecturally appropriate garage, curated landscaping, and the restoration of a unique 1893 Columbian Exposition ticket booth in the side yard. Inside, original finishes have been revived, including colored sand wall textures and restored woodwork stains. Thoughtful updates have been made to ensure modern comfort while respecting historical integrity: the kitchen has been reimagined with two prep areas for a chef's experience, while the second and third-floor bedrooms and bathrooms have been remodeled with a historical sensibility. The lower level has been transformed into a luxurious recreational space, featuring a family room, billiard room, wine cellar, kitchenette, and guest suite. The main floor welcomes you through a graceful front porch and foyer into the central Gallery, which opens seamlessly into the Living Room with fireplace and built-ins and continues to the Library and formal Dining Room-ideal for gatherings and entertaining. A veranda and powder room complete this level. Upstairs, the second floor offers three spacious bedrooms, two full baths, a laundry room, and a charming four-season sleeping porch. The corner primary suite includes a fireplace and a serene sitting area overlooking the tree-lined street. The third floor functions as a self-contained studio apartment with bedroom, full bath, study/library area, and storage. Just two-and-a-half blocks from downtown Oak Park, this home offers walkable access to shops, restaurants, parks (including Austin Gardens), a fitness center, movie theater, and both CTA and Metra public transit. This is more than a home-it's a work of art, lovingly preserved and updated for modern living. The Hills House offers a once-in-a-lifetime chance to own a true piece of architectural history.
