Welcome to 12789 Royal Oaks Ln, a beautifully maintained 2021-built home offering 4 bedrooms, 3 full baths, a dedicated office, and a versatile floor plan in Mercer Crossing.

A separate front office provides a true work-from-home space without sacrificing a bedroom. The open living, dining, and kitchen areas flow together for everyday living and entertaining, anchored by a fireplace and spacious kitchen. Upstairs, a large 21' x 17' game room, two additional bedrooms, walk-in closets, and a full bath create a fantastic second living area—ideal for a media room, game room, or children's retreat. Thoughtful owner upgrades include custom window shades with remote-operated shades in the family room, additional recessed lighting, under-cabinet kitchen lighting, ceiling fans, a whole-home water softener, and an under-sink RO drinking system with a dedicated island faucet. The garage features an epoxy-coated floor, while the extended garage-to-backyard fence and gate add privacy and functionality. Fresh fence staining, a raised stone flower bed, and a back-porch gas connection for grilling add even more appeal. Enjoy convenient access to I-635, Las Colinas, Irving, and Dallas, with major employment centers, shopping, dining, and entertainment within easy reach, plus nearby parks, trails, and recreation.
