America's First LEED Platinum Builder
Setting the standard for sustainable construction since 2001
Pioneers of Sustainable Construction in America
When the U.S. Green Building Council introduced LEED certification, TG Construction saw the future of building. In 2001, we became the first company in America to complete a LEED Platinum project.
We didn't stop there. We built the next two Platinum buildings, establishing ourselves as the nation's leading sustainable construction experts.
Today, with 7 certified projects under our belt, including 5 at the highest Platinum level, we bring unmatched expertise to sustainable construction.
“TG was the first construction company in the United States to successfully complete a LEED Platinum project.”
And we then went on to build the next two.
