Upgrades include a new foundation, French drain with sump pump, new roof, new HVAC with ducting, full electrical rewire with upgraded panel, PEX plumbing with future expansion adapters, spray foam insulation beneath the floor plate, new attic insulation, energy-efficient windows, Craftsman-style siding, and fresh interior/exterior paint. Cat-6 wiring throughout with centralized coax/fiber hub. Designed to support a future two-story addition allowing 4,000+ SF total living area or pool.
