Nassau Bay Town Square's first retail businesses should be open by this summer, including a Wings N More restaurant, a Texas Citizens Bank branch and a Verizon store.

The Bay Area Houston Economic Partnership will also move in, leaving 17,000 to 20,000 square feet available to be leased out from the project's 35,000-square-foot first phase.

A groundbreaking ceremony was held Friday, but actual construction started last month on the retail portion of Griffin Partners' $150 million mixed-use development at NASA Parkway and Saturn Lane.

The construction is the development’s first of two phases of retail space and should be finished by June with tenants moving in by the end of July, said Susan Tyree, an executive leasing assistant for Griffin Partners.

Construction of the second phase of the development will start this summer and add another 35,000 square feet of retail space, with Five Guys Burgers and Fries and Baker Street Pub already signed up.

The development’s 313 apartment units were recently finished and are starting to be leased. It will eventually also include 600,000 square feet of office space in three buildings, 70,000 square feet of retail space, a 27,000-square-foot conference center, a six-story Courtyard by Marriott hotel with 176 rooms, and a new 8,000-square-foot City Hall building paid for by Griffin.

"We're pleased with it," Nassau Bay City Manager Chris Reed said. "It's moving along pretty good."
