A developer filed state plans Wednesday for four office buildings on Legacy Drive with a combined estimated cost of $458.2 million.
The four projects, each labeled "Project Eagle" and numbered Building 1 through Building 4, were logged Oct. 14 in a Texas Department of Licensing and Regulation project database. All four list the same address, 5500 Legacy Drive, and the same owner, KDC Legacy Eagle HQ Development One LLC, with an address on Knight Street in Dallas.
What the filings describe
Each filing describes new office construction with an entry lobby and supporting spaces:
- Building 1: about 249,000 square feet, estimated at $115.4 million
- Building 2: about 225,000 square feet, estimated at $68.9 million
- Building 3: about 225,000 square feet, estimated at $72.9 million
- Building 4: about 679,000 square feet, estimated at $201 million
Together that is roughly 1.38 million square feet of office space. All four list a construction start of Dec. 1, 2026, and completion by March 31, 2029. The projects are privately funded, and the tenant field on each filing reads "not assigned." Dallas firm M. Arthur Genler Jr. & Associates is listed as the designer.
The registrations are listed in the state's architectural barriers program, which tracks accessibility review and inspection. They do not say who will occupy the offices.
The AT&T campus nearby
KDC is the developer working with AT&T on the company's planned headquarters campus in Plano. The Dallas Morning News reported in September that an entity tied to KDC bought the 54-acre former Electronic Data Systems site at 5400 Legacy Drive in May, that AT&T will be the developer's tenant and that the company has an option to buy the site later.
Under its agreement with the city, AT&T must put a minimum of $1.35 billion into construction there and build a minimum of 2 million square feet for offices, amenities and retail.
