Introducing 624 Armstrong Ave, a gem-of-a-property and an historic treasure. This 3,411 sq ft, 4 bed, 2 bath has been in the same family for 74 years. The family began a complete renovation in 2015 modernizing the original cape-cod design with custom fixtures and finishes. The result: beautiful, charming, sophisticated indoor and outdoor living spaces that indulge every comfort and convenience. The upgrades and finishes in this home are second to none, including oak hardwood floors, hardwood built-ins, wainscoting, crown molding, ceiling fans, plantation shutters & custom brass light fixtures in every room. The warm, bright, kitchen is 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.
