DALLAS – August 12, 2025 – Granite Properties, a commercial real estate investment, development and management company, and Highwoods Properties (NYSE:HIW), a publicly-traded real estate investment trust (“REIT”), today announced the opening of 23Springs in Uptown, a highly desirable mixed-use neighborhood in Dallas. At 63 percent leased pre-opening, the 641,563-square-foot development features a Class-AA, 26-story, 625,215-square-foot office tower, two freestanding restaurant buildings totaling approximately 16,348 square feet and a half-acre park. The project has transformed the corner of Maple Avenue and Cedar
Springs Road into a new focal point for business and leisure.

23Springs has attracted several leading financial, legal and real estate companies, including Sidley Austin LLP, Savills and Bank OZK, which provided construction financing for the development. Two of the three restaurant spaces have been leased to Wish You Were Here Group’s  Élephante  and Little Ruby’s Café.

“I am proud to welcome 23Springs, an innovative new office development, to Uptown Dallas,” said Dallas Mayor Eric L. Johnson. “Dynamic work environments with vibrant neighborhood amenities, including substantial green spaces, enhance Dallasites’ quality of life while reflecting and reinforcing Dallas’s position as a
premier business and financial center,” he added.

“We’re excited to deliver a new neighborhood destination with an iconic office tower, restaurants and a vibrant park in Uptown Dallas. 23Springs appeals to industry-leading companies seeking the highest quality design, experience and location to benefit their employees and clients. This project is focused on maximizing productivity, comfort and connection through a unique set of collaborative spaces and amenities for top talent to enjoy. We’re proud to contribute to the vibrancy and walkability of Uptown with a neighborhood park and restaurants Élephante and Little Ruby’s,” said Paul Bennett, Senior Managing Director, Granite Properties. “The building’s early leasing success validates our growth strategy focused on developing and acquiring best-in-class buildings located in exceptional mixed-use environments in high-growth Sun Belt cities,” he added.

“We couldn’t be happier with the partnership and progress we’ve made with Granite at 23Springs. Early leasing momentum at 23Springs reflects the strong demand for well-crafted and commute-worthy workplaces in Uptown Dallas,” said Ted Klinck, President and CEO, Highwoods Properties.

“As both the construction lender and the lead tenant, it has been a pleasure partnering with Granite Properties to help bring an architectural achievement like 23Springs to life,” said Brannon Hamblen, President, Bank OZK. “In addition to the five floors we leased in the tower that provide a world-class workplace for our employees, we’re excited to announce that our full-service retail banking center on the building’s stunning ground floor is now open and ready to provide our clients with the highest level of service,” he added.

“The opportunity to be an anchor tenant and establish a new home for Sidley in the top floors of 23Springs has been really exciting for our team in Dallas,” said Scott Parel and Angela Zambrano, Sidley’s co-office managing partners. “Our continued growth in Dallas is demonstrated by our need for a larger, state of the art space that offers the hospitality forward amenities that our clients, lawyers and professionals will appreciate and enjoy for years to come.”

23Springs is the tallest office building in Uptown and adds a striking presence to the skyline. Designed by GFF and constructed by DPR Construction, the elegant tower has identifiable double X-brace columns, allowing for a 360-view of Uptown and Downtown Dallas. A six-level parking garage is located underground to make way for the restaurant buildings, park and walkable streetscape. Élephante, an upscale coastal Italian restaurant, will occupy a two-story building covering 10,791 square feet when it opens in Q1 2026. Little Ruby’s, a casual Australian café open all day for breakfast, lunch and dinner, will occupy a one-story building covering 3,024 square feet when it opens in Q4 2025.

Inside the office tower, amenities reflect the expectations of the modern workforce and include:

    • a two-story, hospitality-driven lobby featuring a coffee bar
    • an indoor lounge with a golf simulator
    • a large conference center and boardroom
    • a 4,500-square-foot fitness center
    • an outdoor lounge with full AV-enabled conference facilities
    • private motor court
    • valet parking
    • EV charging stations and bike storage

23Springs’ lobby features the largest interactive indoor video wall in Dallas. The 26 ft tall and 47 ft wide digital wall wraps a corner and responds to people as they approach or walk past the wall. The wall’s content consists of four worlds called Underwater Abstractions, Sacred Garden, Surrealist Fauna (animals) and Icons (landscape images). The worlds transform throughout the day and have the following stages:  Sprout, Growth, and Pollinate. The wall can show live TV, movie content, or serve as a welcome screen for customers and guests. Content is created by Volvox Labs, and the video wall is made by Planar.

23Springs is Fitwel certified and designed for LEED Silver certification. Sustainability and wellness features include 14-foot floor-to-ceiling windows, destination dispatch elevators, indoor air filtration, and ample green space to work or meet outdoors. A rainwater harvesting system and low-flow water fixtures reduces indoor water consumption by 50% and energy consumption by 14%. Located at 2323 Cedar Springs Road, 23Springs is easily accessible through three points of ingress and egress. With a walk score of 93, Hotel Crescent Court, Stanley Korshak, popular Uptown restaurants, shops, entertainment and the Katy Trail are just steps away. The project is within a two-minute drive to the Dallas North Tollway, a four-minute drive to North Central Expressway, a 12-minute drive to Dallas Love Field Airport, and a 23-minute drive to Dallas-Fort Worth International Airport.

23Springs is being leased by Granite’s inhouse leasing team consisting of Robert Jimenez, Burson Holman and Elizabeth Fortado. For more information, please visit: www.23springs.com
