15380 Tullgean Drive Tucked behind a gated entry on 4.47 acres in Tullamore - Milton's most coveted equestrian community - this 22, 000 square-foot custom Mediterranean estate was purpose-built for the way families actually live. With 11 bedrooms, 7 full and 4 half bathrooms, including a fully equipped attached guest house, and a complete terrace-level apartment, every generation has room to live fully and privately under one extraordinary roof. The home announces itself from the threshold: a cathedral dome entry foyer framed by grand columns, iron spiral staircases, and hand-crafted millwork running top to bottom on every level. Hardwood floors carry throughout. The great room climbs past twenty feet with a commanding fireplace at its center. A chef's kitchen delivers commercial-grade appliances, gas cooktop, dual sinks with prep sink, oversized island, butler's pantry, eat-in dining, and a sunroom that opens to a tile patio overlooking the grounds. The primary suite offers a morning coffee bar, two custom his-and-hers built-in closets, dual fireplaces, soaking tub, walk-in shower, and double vanities. A wood-paneled executive office, formal dining room, and seven fireplaces total complete a main level of uncommon refinement. The terrace level is a private world of its own - exposed brick, two fireplaced living rooms, a wine cellar, theater room, full apartment with kitchen, and a second entertaining kitchen that opens directly to the pool. Enjoy the resort-style grounds: heated saltwater pool, lap pool, koi pond, outdoor cabana's, tile patio, Juliet balconies, and lush landscaping across 4.47 gated acres. The attached guest house - with full kitchen, living room, bedrooms and bath - offers complete independence for extended guests or family. Four-car garage with secondary driveway, an 8-car parking pad, and carriage way. Terracotta roof. The entire exterior of the estate was freshly painted last year. Tullamore offers a rare lifestyle with a 4-mile private walking and riding trail, tennis and pickleball courts, and a community riding arena. Located in the heart of Milton, Georgia - a city recognized for its commitment to estate-scale living, equestrian heritage, and green space - this property is zoned for Milton High School and benefits from one of Fulton County's most respected public school systems. Just minutes from Publix, Scottsdale Farms, and 7 Acre Bar & Grill, with nearby favorites like Historic Crabapple, and Avalon - all while offering the space, privacy, and peaceful setting that feels a world apart. Custom-built. Thoughtfully designed for multi-generational living.
