A distinguished landmark of Princeton history, the Watts A. Johnson Home (circa 1900) is a rare offering where architectural heritage meets refined modern living. Once featured in the May 4, 1904 Bureau County Republican as the “New Residence of Mayor Watts A. Johnson,” this extraordinary home stands as a testament to timeless design and enduring quality. The meticulous restoration of the home spanned 16 years, honoring its original character while seamlessly incorporating modern comforts and thoughtful upgrades. From the moment you enter, a grand, wide foyer sets a tone of elegance. The main level unfolds into a front den, formal living room, and dining room highlighted by Brazilian cherry flooring. The custom chef’s kitchen is both beautiful and functional, featuring granite countertops, a substantial island, soft-close custom cabinetry, upgraded stainless steel appliances including a gas Five Star stove, and a discreet walk-in pantry designed to keep everyday conveniences elegantly out of sight. Throughout the home, details such as crown molding, wainscoting, painted and natural woodwork, and radiant heated tile flooring throughout all tiled areas reflect exceptional craftsmanship. Architectural distinction continues with a striking turret-style facade extending to the second level, accented by graceful, curved glass windows. A main-level full bath allows for comfortable long-term living, while a built-in bench with storage at the foot of the staircase adds both charm and function. The second level offers four well-appointed bedrooms, two full bathrooms, a laundry room, abundant closet space, and a walk-up attic. Just beyond the landing, a charming office or homework retreat overlooks the east yard, providing a quiet and inspiring space. Behind the scenes, modern systems ensure everyday comfort. Most windows have been upgraded to Marvin brand replacements (with select exceptions). An updated zoned boiler system provides efficient heating, while a modern central air system delivers cooling to both the first and second floors. A new tankless water heater was installed in 2026 for your convenience. A generous rear walk-in entry provides an elegant solution for coats and shoes. The lower level offers ample storage and includes a toilet and sink. Outside, a beautifully preserved vintage carriage house serves as a two-car garage, featuring wood flooring and a fully floored upper level for additional storage. The corner lot totals .77 acres, offering both presence and privacy, as well as a charming new fence (2023) and gorgeous brick patio (2024). Safety is of utmost importance as reflected by the addition of a radon system (2023) and removal of an old lead water line (2023) which was replaced with updated materials. Additionally, a new roof in 2023 allows for peace of mind for decades to come. A visit here is an invitation to experience one of Princeton’s most thoughtfully restored historic residences, where legacy, luxury, and livability exist in perfect harmony. One fireplace is non-operational.
