## Description

### Agent Description
Welcome to an exclusive new enclave of just six newly built luxury single family residences in the prestigious City of Walnut, celebrated for its award winning Walnut Valley Unified School District. Set on expansive lots with breathtaking hillside views, each home offers approximately 2,432 to 2,900 square feet of refined living space on generous lots ranging from 9,950 square feet to 13,630 square feet, featuring four bedrooms and four and a half bathrooms. Designed for modern comfort and elegant entertaining, these residences showcase soaring ceilings, luxury vinyl plank flooring, sleek iron railings, and a bright open concept layout anchored by a gourmet kitchen with quartz countertops, premium stainless steel appliances, custom cabinetry, and a large center island. Walls of windows and sliding glass doors invite abundant natural light and seamless indoor outdoor living, opening to landscaped backyards with lush lawns, pergola covered patios, and ADU potential. Highlights include a main level junior suite ideal for guests or multi generational living, a spa inspired primary retreat with a soaking tub and walk in closet, two car garages with stone facades, private side yards, no HOA, no Mello Roos, and a prime location near major freeways, shopping, and top rated schools, making this a rare opportunity to own brand new luxury in one of Walnut’s most desirable neighborhoods.
