The Onyx is celebrating its arrival with a Grand Opening ribbon-cutting ceremony on Wednesday, September 2 at 10 a.m., joined by local officials and invited guests, and featuring tours of The Onyx's model residence and resort-caliber amenities.

"From beautiful apartment units with high-end finishes, to the spa, fitness center, inviting outdoor spaces and more, each detail at The Onyx is meant to help residents live well and feel at home," said Natalie Dustman, Managing Director at Century Living. "We're proud to bring this vision to a community as vibrant as RidgeGate, and we look forward to showcasing everything The Onyx has to offer at our Grand Opening ceremony."

 

A NEW CHAPTER OF GROWTH AT RIDGEGATE

The apartment complex's arrival coincides with a period of rapid growth at RidgeGate, Lone Tree's 3,500-acre planned community spanning both sides of I-25. Located east of the highway in RidgeGate's up-and-coming Couplet District, The Onyx brings 327 residences and a full suite of resort-inspired amenities to the area.

Close to The Onyx, a 123,000-square-foot King Soopers Marketplace and the 80-acre High Note Regional Park are both under construction—with a single-level retail strip also planned within walking distance—part of a broader east-side expansion projected to bring significant new shopping, recreation, and employment to Lone Tree in the years ahead.

 

ADDITIONAL COMMUNITY HIGHLIGHTS:

The Onyx offers a curated collection of floor plans, each offering quality included features and a polished sense of style. Phase I of the project is now open—comprising more than half of the community's residences, along with a full suite of wellness-focused amenities—and Phase II will be completed soon.

  • One-, two-, and three-bedroom floor plans featuring quartz countertops, stainless-steel appliances, wood-style flooring, and dual-sided walk-in closets with a full-size washer/dryer set
  • Full wellness spa with sauna, steam room, cold plunge, and outdoor hot tubs
  • 5,000-square-foot, two-story fitness center with free weights, Olympic weightlifting, and premium cardio
  • Four-season pool with a dedicated lap lane and outdoor social spaces
  • Sky Lounge with accompanying sky deck, dedicated clubroom, co-working spaces, and private conference rooms
  • Residents' canteen, on-site market (snacks and household items), workshop and makerspace, social gathering spaces with fire pits
  • Dog park and pet spa, bike wash station, package delivery, and on-site storage
  • Quick access to I-25 and E-470
  • Minutes from light rail and outdoor recreation
  • Convenient proximity to the Denver Tech Center

 

UPCOMING CENTURY LIVING PROJECTS

The Onyx is one of several additions to Century Living's growing portfolio across the Denver metro. In Denver's LoHi neighborhood, Century Living is developing The Stevie, a five-story, 116-unit luxury boutique apartment community featuring a pool, sun deck, fitness center, and resident lounges, with leasing expected to begin in 2028.

In south Denver, Century Living is also redeveloping the site of the former Regal Continental Theater near I-25 and Hampden Avenue into a new apartment community, situated near a King Soopers and RTD light rail.
