In 2004, José Luis Astiazarán, then the president of Real Sociedad, launched a project called Gipuzkoarena. Planned to be finished in 2007, it was intended to increase the stadium's capacity to 42,000, which would include the removal of the athletics track. The project also intended to construct a hotel and shops, among other items. This proposal was soon rejected by the city council and left behind.
Towards the end of 2007, Badiola, as candidate for president of Real Sociedad, proposed that the club buy the stadium. This was also soon rejected by the city council. In 2008, Badiola, already as president, made another two proposals for the stadium, one of them similar to Gipuzkoarena. These proposals were going to be studied by the city council, but after 20 December Badiola was no longer the club's president. Later, the next president, Jokin Aperribay, launched a new attempt to reform the stadium.
