The home has been extensively improved at the infrastructure level, including a new roof, all-new electrical and plumbing systems, new HVAC, insulation, and re-finished windows. Thoughtfully integrated smart-home enhancements include Nest climate control, two high-speed EV charging stations, and a pre-wired security system with CCTV, offering both comfort and peace of mind.
