Developers making plans for a huge mixed-use project north of downtown Dallas have added more land to the deal.

Dallas' DeLaVega Development has been working for two years on a planned high-rise complex on North Central Expressway next to the Cityplace Tower. The proposed development would include a residential tower, luxury hotel, shopping, restaurants and other buildings.

Now, a partnership that includes DeLaVega has bought more than 16 acres next door to make the development even larger, according to Dallas County deed records.

The vacant block at North Central and Carroll Avenue was acquired from Dallas developer Trammell Crow Co., which planned to build a shopping center on the site, but construction never got off the ground. A spokesperson for Crow confirmed the sale.

Combined with the 10 acres DeLaVega already owned at Haskell and North Central, the property is one of the largest development sites near Dallas' booming Uptown district.

Parts of the property are occupied by vacant buildings that once housed technology company Affiliated Computer Services.

Demolition signs are posted on those properties, and the city has issued a demolition permit, records show.

Crow had owned the property since 2013. The developer tore down an office tower and other buildings on the property to make way for a Sam's Club big box store and several small retail buildings on block. But neighbors sued to halt the huge discount center, and Crow downsized the project. Construction never moved ahead.

DeLaVega Development's CEO Artemio DeLaVega said it's too early to discuss plans for the just-sold property.

Dallas law firm Kane Russell Coleman Logan represented the buyers and coordinated the transaction.

DeLaVega Development is calling its proposed mixed-use project for the site the Central. Before adding the Crow property, it was to be almost 3 million square feet.

DeLaVega Development has business and real estate holdings in Mexico and Texas. The company's website lists more than a dozen real estate projects in Texas plus properties in Arizona, South Carolina, Georgia and Louisiana.

As DeLaVega's project on Central Expressway moves ahead, the landmark Cityplace tower across the street is getting a major makeover.

An investment affiliate of Dallas' Highland Capital, which bought the 42-story high-rise in 2018, has announced plans to convert part of the 31-year-old building into a 233-room InterContinental Hotel.
