The World Trade Center building opened its doors for the first time since September 11th, 2001 last week. The building, now the tallest in America, welcomes the publishing firm Conde Nast as one of its first tenants. Conde Nast—publisher of Vogue, The New Yorker, Vanity Fair, Women's Wear Daily, and GQ, among others—has only moved in about 200 employees, with the rest of the 3,400 employees to arrive in early 2015.

The new World Trade Center building and its surrounding area covers 16 acres; it replaces the area where the Twin Towers once stood. The opening of this building is an important milestone for New Yorkers—especially those who were affected by the September 11 attacks. The excitement swirling around this new iconic New York City building is obviously in sharp contrast with the feelings of sadness and horror that have loomed over the site for the last 13 years.

Currently, the building is only partly leased, leaving about 40% to be filled. Many other companies plan to fill the floors of 1WTC, including Kids Creative, Legends Hospitality, the BMB Group, and Servcorp. The future of the new World Trade Center site looks bright as they expect more companies to fill the remaining spaces. The brand new observation deck is also set to open to the public soon. Moving into 1 World Trade Center will be an important shift for companies like Conde Nast, who look to evolve their digital presence in the future.
