construction contract for their design for the new building, referred to as "The Bathtub". The new Stedelijk has an exhibition surface area of 8,000 square meters, which is double its previous gallery space. Michael Kimmelman, architecture critic for The New York Times, wrote of the museum's addition, "I can't recall seeing a more ridiculous looking building than the new Stedelijk Museum." The Los Angeles Times called the extension "oversized, antiseptic and mismatched". When Alvaro Siza had originally designed the plans, the reopening was scheduled for 2007. In 2004, when a new competition was held, it became clear that this date was not achievable. Although the renovated original building was completed in early 2010, conditions were not suitable for exhibiting artworks because there was no climate control system, which was to be installed in the new wing. The press poured criticism on the delays. A campaign by Dutch cultural entrepreneur Otto Nan, "Stedelijk Do Something", urged people to text their disappointment about the delays. This drew considerable media attention and a huge response from social networking sites like Twitter and Facebook. Nan hoped that what he referred to as an "amicable coup" would attract political attention with an occupation of Museum Square. By sending SMS messages, people could raise money to help the museum re-launch a little sooner. With even more delays in 2011 when contractor Midreth went bankrupt, the plan to re-open in the spring of 2010 was moved to 2012. The restored original building went ahead and opened with a temporary exposition in 2010, which attracted about 223,000 visitors. Contractor VolkerWessels finished the construction in February 2012, after which the climate control system was set up. After eight years of work, the new Stedelijk opened on 23 September 2012. With the renovation and expansion, the highlights of the collection are on display in the old building in a series of changing presentations. The new wing consists of a large glassed entrance, which opens onto the Museum Square, and galleries for temporary exhibitions on the upper level and in the basement. It also houses the museum shop, restaurant and library, as well as an auditorium. The inaugural exhibition, entitled "Beyond Imagination", was a show of work by emerging Amsterdam artists. A retrospective of the late Los Angeles artist Mike Kelley followed in December 2012. The completion of the project cost a total of €127M, €20M more than estimated in 2007,
