General Motors is doubling the size of its design studios as part of a previously announced $1 billion investment and renovation of its global technical center in suburban Detroit.

The automaker on Wednesday said it will break ground in mid-2018 on a 360,000-square-foot studio building, which will surround its historic design dome, auditorium and viewing patio. The new studio will connect to the company’s existing 350,000-square-foot design center.
