In February 2011, the FFT voted to keep the tournament at Roland Garros, citing the prohibitive expense ($630 million to $1 billion) of building a new venue from scratch versus a projected $370 million to carry out the proposed expansion. Further details of the plan were announced in May 2013, including a complete rebuild of the Chatrier court on its existing foundations in addition to the new roof and lights, and a larger "Place des Mousquetaires" in the area occupied by Court 1. The new stadium at Porte d'Auteuil would be built below ground level, with greenhouses surrounding it on all four sides. Project deadlines were pushed back from 2016 to 2018. Local residents, wildlife enthusiasts and municipal authorities continued to voice opposition to the plan, which would increase the Roland Garros grounds from 21 acres (8.5 hectares) to about 33.8 acres (13.5 hectares).
