Chelsea have consulted the company who built Beijing's Bird Nest Olympic Stadium and Bayern Munich's Allianz Arena over their plans for Stamford Bridge.
Swiss firm Herzog & de Meuron are contributing towards the redevelopment that will see Chelsea's home increased to a 60, 000- seater venue.
The expansion comes after the club failed to locate land for a new stadium, and as of last June it has become a case of redeveloping their existing ground rather than seeking a new area on which to build.
A statement from the club last summer read: “The study will assess the feasibility of an expansion of the stadium within the existing historic site boundaries, potentially to enlarge its capacity, enhance its facilities and improve the movement of people and vehicles on match and non-matchdays."
