The 1-million-square-foot square foot Knox Street mixed-use development has topped out construction, developers told The Dallas Morning News.

The joint venture partnership of BDT & MSD Partners, Trammell Crow Company, Highland Park Village Associates, and The Retail Connection is behind the massive 4-acre project on the eastern edge of Highland Park.

The development will include 150,000 square feet of office space, 100,000 square feet of retail, a 27-story, apartment tower, a half-acre park with direct connection to the Katy Trail, as well as The Knox Hotel and Residences, a 140-room hotel and 47 luxury condominiums operated by Auberge Collection.

TCC representatives declined to say how much the partnership invested in the project or its estimated worth. But the project was once called Dallas’ most expensive real estate project.

“Reaching this milestone at Knox Street is a testament to the dedication and collaborative spirit of the entire development team,” Joel Behrens, Market Leader for TCC Dallas-Fort Worth, said in a statement. “It’s incredibly rewarding to see the project’s vision, which we’ve been working on for so long, finally take shape.”

One of the first buildings to be delivered will be the 27-story multifamily tower. Called The Lora, the building will feature 186 apartments. The one-, two-, three- and four bedroom units will range from 800 to 3,500 square feet. The building was designed by architecture firm Woods Bagot.

The Knox Hotel and Residences is set to open in late 2026, and nearly all of the condo units have sold out, the group said in a news release. The condos range from 2,500 square feet to over 15,000 square feet. Pricing reportedly started at $4.5 million.

The hotel will feature several restaurants, bars, lounges, event spaces and a full-floor spa and wellness center connected to an outdoor pool and bar that offers views of downtown Dallas.

The nine-story, 150,000-square-foot office building 3333 Knox is scheduled for completion in late 2026. It’s been 100% preleased since fall 2024. Anchor tenant ISN Software Corporation will be joined by Paul Hastings LLP and BDT & MSD.

The development comes as Knox Street continues to land high-profile retail tenants. Italian hospitality group Sant Ambroeus announced Knox Street as the location of its first Texas outpost. It will anchor the base of the development’s apartment tower.

In late 2025, a group of lifestyle brands announced plans to open locations at Knox Street, three of which are making their Texas debut. The retailers include DÔEN, STAUD, TOTEME and TWP.

Additional project announcements are expected in the coming months. Retail leasing is led by Stephen Summers and Kaitlin Travis of Highland Park Village Associates.

The development has been planned since 2017. Plano-based Beal Bank provided more than $600 million in financing for the Dallas project, according to previous News reporting.

Coming off the success of Knox Street’s office lease up, the joint venture is also behind Knox & McKinney, a 12-story, 300,000-square-foot office and retail development at 4544 McKinney Avenue. The site was formerly home to Tex-Mex restaurant Chuy’s.
