## Description

### Agent Description
Introducing the brand new single family home in Walnut, built in 2026 and located within the highly sought after Walnut Valley Unified School District, with no HOA and no Mello Roos. This exclusive enclave offers approximately 2,467 square feet of refined living space on generous lots ranging from approximately 12,060 square feet, floor plans featuring four bedrooms and three and a half bathrooms to four and a half bathrooms. Designed for modern comfort and elegant entertaining, each residence showcases soaring ceilings, luxury vinyl plank flooring, sleek iron railings, and a bright open concept layout centered around a gourmet kitchen with quartz countertops, premium stainless steel appliances, custom cabinetry, and a large center island. Walls of windows and sliding glass doors bring in abundant natural light while creating seamless indoor outdoor living, opening to landscaped backyards with lush lawns, pergola covered patios, and potential ADU possibilities. Additional highlights include a main level junior suite ideal for guests or multigenerational living, a spa inspired primary retreat with a soaking tub and walk in closet, two car garages with stone facades, private side yards, hillside views, and a convenient location near shopping, freeways, and top rated schools. Backyard photos are AI generated concepts intended to illustrate potential landscape design possibilities.
