624 Armstrong embodies the dream of owning a singular Fort Collins residence, as pristine & polished as it is historically rich. This unique gem, owned and lived in by the same family since it was built in 1951, offers a level of detail that speaks directly to the luxury client who values signature identity, unparalleled craftsmanship, and countless amenities. A total renovation beginning in 2015 elevated the classic cape-cod design with the timeless sophistication of impeccable modern fixtures and finishes. Throughout the 3411 sq ft, 4 bedroom, 2 bath home you will find oak hardwood floors, hardwood built-ins, wainscoting, crown molding, ceiling fans and plantation shutters. Bespoke brass light fixtures, paneled ceilings and leaded glass windows serve as works of art. The kitchen is lavishly outfitted with a new Cove dishwasher, Wolf induction cooktop, cherry cabinetry, quartz countertops and marble backsplash. Both bathrooms include steam showers; the primary features heated travertine floors, deep soaking tub & double sink. Undergirding design is livability and sustainability including a tankless hot water heater, R38 insulation, gas fireplace, humidifier, UV air purifier & a new trenchless sewer replacement. The heated, tandem garage is finished with slate wainscoting & equipped with a 200 amp electric port for EV charger. Discover an additional ~360 sq ft finished loft above the garage, situated beneath a charming cupola. Finally, relax & entertain in an exceptional outdoor living space, anchored by a 2nd gas fireplace, & surrounded by a canopy of mature trees. This outdoor space has been lovingly cultivated for 74 years and the result is a private, verdant retreat. All of this in the historic Mantz Addition neighborhood: a prime central location within minutes of the beautiful CSU campus, Old Town, the Lincoln Center, Dunn Elementary IB school, restaurants, shopping & every amenity.
