West Bromwich Albion and owner Jeremy Peace are planning to install an additional 3,500 seats to the Hawthorns stadium over the next three seasons.
The stadium currently seats 26,500 spectators and it is hoped the additional seating will provide significant extra match day revenue.
Peace said: “Our medium-to long-term plans include an extension of the Hawthorns to around 30,000-seat capacity within the next three years.”
Since Roy Hodgson took over the side has secured Premier League survival this season and Peace is now looking for the club to move forward.
“We believe it is the right thing to do as we endeavour to move the club forward and pro-actively encourage the next generation of supporters to come to the Hawthorns,” he said.
He added that the stadium renovations will be completed “regardless of divisional status”.
