Set on a quiet cul-de-sac, this 4-bedroom, 2.1-bath residence offers approximately 3,345 square feet of well-designed living space with both everyday comfort and formal entertaining in mind. A dramatic two-story foyer with an elegant chandelier leads to a bright interior featuring a primary staircase from the foyer and a secondary staircase from the family room. The main level includes refinished hardwood flooring, freshly painted interior walls throughout, a private first-floor office, formal living and dining rooms, and comfortable gathering spaces with natural flow. The kitchen features newer tile flooring along with a new range and microwave installed in 2026.
