Welcome to 1499 Rosebank, THE ICONIC hydrangea house in Harmony. This exceptional former model home blends timeless architectural details with extensive functional upgrades. The true showstopper is the completely reimagined backyard, professionally graded to create a level, highly usable outdoor oasis designed for both entertainment and everyday enjoyment. At its center is a heated and chilled saltwater pool featuring an automatic keypad cover, extended lounging ledges, a tanning ledge with bubblers, and basketball goal. Upper-level covered and open pool-level patios, expansive custom hardscaping, low-maintenance turf, sophisticated landscape lighting, irrigation, mature privacy landscaping and cedar panels, and a fully fenced yard create a spectacular retreat. Custom interchangeable load-bearing grates over egress windows provide sunlight in winter and additional patio area while pool is open. Inside, thoughtful improvements continue with substantial crown molding, built-ins, wainscoating accents, soaring architectural arches, fresh paint, updated lighting, custom window treatments, a beautifully remodeled home office, and an added mudroom. The primary suite features a large shower with dual sprays, while the full finished basement offers additional living and entertaining space complete with a wet bar. Bonus playroom above garage has its own dedicated HVAC. Newer 5 year old roof, newer HVAC, updated sump pump with backup, recently replaced garage door, and freshly painted exterior. Rich in character, exceptionally well improved, and designed for effortless indoor-outdoor living, this Harmony home offers a true private retreat while also having access to one of Westfield's most amenity-rich neighborhoods: multiple community pools, 24/7 fitness center, tennis, pickle, basketball, soccer, playgrounds, dog park, expansive green space and walking trails, clubhouse and event spaces, community garden, year round social events, clubs, fitness classes and family activitie
