The 6,500-square-foot Austin Aquatics and Sports Academy on Southwest Parkway, which has been under construction since June, opened to triathletes and professional swimmers Jan. 20, owner Kevin Thompson said.

"It has taken longer than we thought it would, and its very difficult to build in that part of Austin," he said, citing environmental regulations. "I think in the end we built a great facility."

The $6.5 million academy and pool are among many projects along the corridor moving forward in 2015.

Stratus Properties Inc. broke ground in early January on the first phase of a development tentatively called Tecoma, with its first multifamily units slated to open by October, Stratus President and CEO Beau Armstrong said.

The first phase consists of about 300 multifamily units and 200,000 square feet of commercial space. Stratus is working with potential commercial users, Armstrong said. Stratus developed plans in the 90s for the $700 million project north of Southwest Parkway, which will include 1.5 million square feet of commercial space, about 1,860 multifamily units and an extension of William Cannon Drive.

Framing work began in January on the fourth phase of Escondera Condominiums, The Enclave at Escondera, said Vicki Reed, real estate agent with Ultima Real Estate. Construction started in the summer on the project, which includes seven buildings and 35 units at 8200 Southwest Parkway on the developments 60 acres, she said.

Construction on another project, the first building in the Encino Trace office park, is slated to be complete by July 1, said Ralph Bistline, senior vice president of Brandywine Realty Trust Co. The two buildings on the 54-acre suburban office campus at 5707 Southwest Parkway will each bring 160,000 square feet of office space to the area.

"It has become a preferred technology corridor and I think that will continue," Bistline said.

Construction is slated to be complete in March on Landmark Conservancy, a four-story, 240-unit apartment project on 22 acres. Oden Hughes LLC finished two apartment buildings and the clubhouse, said Mac McElwrath, Oden Hughes managing director.

"We are just finishing construction on the final four buildings," he said.

Zapalac/Reed Construction Company began site work on All Saints Presbyterian Churchs first building Jan. 19 on Terravista Drive off of Southwest Parkway. David Breeding, All Saints director of finance and operations, said the $10 million construction project is the culmination of a 10-year search for a site. All Saints holds its services at St. Gabriel's Catholic School at 2500 Wimberly Lane as well as at Park Hills Baptist Church on MoPac. The church bought the property in March 2013 and plans to debut its building by March 2016.

"Our church members are spread across the entire Austin area and surrounding areas, so the sites accessibility was [and] is very important to us," he said.
