Twelve Oaks is an established custom-acreage community in the City of Celina, on the Collin County line with Prosper and east of Preston Road (SH 289). Phase I was platted in 2002 and Phase II followed in 2003. About 67 homesites sit on roughly 1.5- to 4-acre lots along Twelve Oaks Lane, Pecan Grove Lane, Cedar Trail, and Oak Bend Trail. Addresses like 2601 and 2656 Twelve Oaks Lane, 3063 Cedar Trail, 3030 Pecan Grove Lane, and 5420 Oak Bend Trail hold custom French, Tudor, and traditional masonry estates—often with circular drives, ponds, and private gates. Owners bring their own builder; horses are permitted on many lots. Mail often uses the 75078 ZIP, but the city is Celina. Households zone to Prosper ISD: Sam Johnson Elementary, Lorene Rogers Middle, and Walnut Grove High. Twelve Oaks Homeowners Association, Inc., managed by Guardian Association Management, collects about $1,600 a year. Those multi-plane custom roofs—hips, turrets, dormers, and long ridge runs—still take North Texas hail and UV. Best Contracting Services inspects Twelve Oaks homes with practical recommendations that protect curb appeal from Twelve Oaks Lane to quieter Oak Bend Trail addresses.
