The Hammers will move into the London 2012 Olympic Games venue in time for the 2016-17 season with the stands including retractable seats that will roll over the running track
The London 2012 Olympic Games venue will still be used for athletics events, but seats in the lower bowl will be extended over the running track in order to bring Hammers fans closer to the action when the stadium is being used for football.
The east London side's hierarchy have fought long and hard to be the preferred tenants of the stadium after it is converted and club supremo Karren Brady believes the move will help the Irons develop.
"Will it be world class? The answer to that is yes. It is going to be a Uefa 4 category, which is the highest level of stadium you can have," she told Sky Sports News.
"Will it look like West Ham? Will it feel like West Ham? Well, West Ham have supremacy for all their fixtures. The answer to that is yes.
"Thirteen of our last matches have been sell-outs, which shows that we do need a bigger ground.
"I think there are a lot of supporters who are interested in seeing what the Olympic Stadium looks like, from home and away."
