This high-performance, energy-efficient home features a tight envelope insulation package, supreme HERS score, ERV fresh air system with 4" HEPA filters, and balanced Make-Up Air. Inside, 4" white oak floors lead to a family room with coffered ceilings and a chef's kitchen boasting handmade custom cabinetry.
