My favorite quote from the Medical Center tour, was about this project being the first private development on U of Texas property. "It took 58 separate legal agreements. We won a ULI award for making the... Read more

For context, we... Read more

Anyone using the USG EcoSmart drywall? I'm writing a short product review and am looking for some quick feedback. I'm particularly curious about reduced greenhouse gas emissions and overall cost. Thanks! Brent
