Both buildings are in the southwest submarket.

"To reduce costs and become more efficient. That is the primary reason we're making these moves," Maury Lane, a Vignette spokesman, tells GlobeSt.com.

One of the upshots is that many employees, used to their own offices, are now sharing space.

Vignette moved into the 121,000-sf Barton Oaks building in 1998 when it was rapidly growing. Its previous offices had been at Far West Plaza I in the northwest submarket. Ford Alexander of the Austin office of Colliers Oxford Commercial has represented the Vignette in its moves.

Four-story Barton Skyway has 195,970 sf. Vignette shares the building with Landmark Graphics Corp.

The slowing economy has hurt the company, which makes large-scale software that helps its clients manage their Web content, as it has most other technology companies. Through the first three quarters ended Sept. 30, Vignette posted a net loss of $561 million on revenues of $244 million. Its shares have rebounded to the $6 range after hitting a low of $3.08 on Sept. 27. About a year ago, Vignette's stock stood at $27.13 per share. Beginning in January, the company has made several rounds of job cuts.

Prentiss Properties, based in Dallas, owns the Barton Oak and Barton Skyway buildings.
