The Hammers have announced that they are hoping to increase the capacity of their new home to 60,000 following high demand for tickets.
The Hammers leave Upton Park this summer after 112 years to move into the Stratford stadium, which was initially slated to have a capacity of 54,000, nearly 20,000 more than their current ground.
However, after confirming that they had supported the Premier League's price cap of £30 for away tickets, the club have now confirmed that they are doing everything they can to allow that number of seats to be increased by a further 6,000.
A statement on whufc.com read: "While the decision to cap tickets at £30 each will cost the club over £2,000,000 in lost revenue over the next three years, the club supported the move to ensure its own supporters benefited from the price cap when they travel to watch the Hammers play away from home.
"The Board are also pleased to confirm that following extraordinary demand for tickets at the Hammers’ new world-class home, West Ham are now doing everything in their power to expand the capacity to 60,000."
The move to a larger ground is coming at the perfect time for West Ham, who are enjoying their most successful season in the Premier League for years.
It is unsurprising that there is heightened demand for tickets amongst the club's supporters, with the Irons currently knocking on the door of a place in the Champions League.
Slaven Bilic's side are currently in fifth place, which would be their highest league finish this century, but are just a single point off breaking into the top four.
