District 121

Situated prominently at the NEC of 121 & Alma, District 121 emerges as a vibrant dining and entertainment epicenter for the region, mainly known as one of the most burgeoning sectors. Nestled adjacent to the sprawling 2,200-acre master-planned mixed-use development of Craig Ranch, District 121 doesn’t merely benefit its direct neighbors; it’s a beacon for the broader communities of McKinney, Allen, Plano, and Frisco.

As the trade area experiences an astonishing growth trajectory, it’s been aptly christened the “Blue Diamond Corridor.” Rapidly evolving, this area is becoming one of the most coveted markets within the metroplex. The District stands as a testament to this growth, joining an array of upcoming exciting ventures. To its name, it boasts:

  • A spacious 30,000 SF retail area and patio restaurant.
  • An 800-space parking garage ensures convenience for its patrons.
  • A 0.72-acre activated park featuring a stage and a 16′ x 9′ LED screen, complemented by cozy fire pits, shaded seating spots, and a generous lawn area.
  • An imposing 200,000 SF, 8-story Kaizen HQ Office standing as a monument to modern business aspirations.

Crafted with precision, District 121 offers an expansive covered patio flanking an invigorated green park. The latter, a testament to its importance and vision, was brought to life with a $2M grant from the MCDC. The retail spaces are meticulously planned, catering to a plethora of activities, from dining and entertainment to concerts and child-friendly play zones.

Every structure within District 121 is deliberately oriented, providing clear-view corridors encompassing multifamily and office edifices. This design invites onlookers and passersby to immerse themselves within this dynamic space. Ultimately, District 121 doesn’t just stand as a premier destination today; it paves the way as a distinctive planning archetype for outdoor-indoor activated entertainment experiences throughout the region.
