• 4143 Buena Vista Townhomes in Dallas. Architect: Ron Wommack Architect in Dallas. Sheet metal contractor: Beech Street Metal in Dallas.

The projects were judged by a panel of architecture and copper industry experts, and the judging was based on overall building design, integration of copper systems, craft of copper installation and excellence in innovation or historic restoration.

“It amazes me every year when we receive so many submissions from all over,” said CDA’s building and construction vice president, Andy Kireta Jr. “Even when the economy is still trying to recover, there are new projects being built that really put copper in the spotlight. It shows that you can’t always put a price tag on quality.”

The architects and contractors will receive commemorative plaques with pictures of their projects etched into the awards. All the projects, including photos and architectural profiles are featured on CDA’s website at:
