Stream Realty Partners' San Antonio office will add a 101k SF Class-A office property to its One51 Office Centre campus in Westover Hills. There isn't an exact date yet for the groundbreaking, but a spokesperson for the company tells Bisnow it will be in Q1 2016 and will deliver by the end of the year.

The new building is Phase 2 of the project. Phase 1 broke ground in 2014 and has been a success for Stream as Westover Hills has become a strong submarket. One51 Office Centre is surrounded by offices for Nationwide Insurance, Wells Fargo, Hartford Insurance, Capital Group, Chase Bank, Microsoft and others.

Phase 2 will be built on 8.97 acres, off Highway 151 at 9810 SH 151. It will be a two-story building with flexible working spaces between 22k SF and 101k SF. The building will feature high ceilings, 24-hour security, oversized windows and seamless access to Highway 151. Construction is estimated to cost $6.4M.

Stream Realty Partners' Central Texas managing director, Carolyn Shaw, will lease the property.
