An unparalleled legacy estate of 1904 pedigree and state-of-the-art modern infrastructure in the heart of East Rock! Designed by the legendary architectural firm Brown & Von Beren, this magnificent 4,060 sq ft, 7-bedroom Colonial stands as the premier luxury landmark on Livingston Street. Deliberately delivered vacant and move-in ready, it sits directly across the street from a Yale Shuttle stop, steps from cafes, markets, and top schools.Mechanically transformed for the modern era, the home features a brand-new 2024 multi-zone HVAC system (all-new air handlers & compressors) serving the 1st, 2nd, and 3rd floors, a dedicated basement AC, an advanced whole-home leak monitoring system, and a 2026 hot water heater. Elite tech and wellness upgrades include a whole-home water filtration system paired with a premium 2026 UV Reverse Osmosis system feeding both the sink and fridge, integrated radon mitigation, dual EV charging stations, and restored high-speed Ethernet/cable wiring throughout.The versatile floor plan perfectly pairs historic chestnut woodwork and newly refinished 1st-floor hardwoods (2026) with an immaculate, extensively painted interior. The layout is highlighted by a private 3rd-floor oasis featuring 3 of the 7 bedrooms, a full bath, and a generous flex area ideal for an au pair or guest suite, already equipped with a farmhouse sink and seamless room to expand into a full kitchenette layout.
