Exhibit 99.1

Chambers Street intends to list its shares on the NewYork Stock Exchange (NYSE). May 8, 2013 Dear Shareholders: We are pleased to provide you with additional information regarding the recent, exciting developments at Chambers Street Properties. Since inception, our objective has been to build a premier real estate organization that seeks to create value for our shareholders through stable cash flow and long-term asset appreciation. We are now pleased to inform you of our intention to list the common shares of Chambers Street Properties on the New York Stock Exchange, or NYSE. Let me provide an overview of the decision to list, what it means to you and our long-term goals as a publicly traded company. We believe our anticipated listing should provide significant new opportunities for Chambers Street and our shareholders, however there is no fundamental change of direction for the Company or its strategy. Our History Together Since our formation in 2004, we have acquired and developed a high-quality industrial and office portfolio comprised primarily of single-tenant net lease properties with an aggregate purchase price of approximately $3.2 billion. We own or have majority interests in 129 properties located across 22 U.S. states, Germany, and the United Kingdom encompassing approximately 34.1 million rentable square feet. Our portfolio has a weighted average age of approximately 10 years and is 98% leased with approximately 82% of its rentable square footage leased to single tenants on a triple net basis. As our company grew, we stayed true to our founding principles: Acquiring high-quality properties in premier locations. Building a portfolio with strong diversification. Focusing on long-term leases to creditworthy tenants. Maintaining conservative leverage to support continued growth. Providing a stable dividend payment to our shareholders. Chambers Street today reflects these principles. Our portfolio has 272 tenants across 25 industries with 7.3 years of average lease term remaining. No individual tenant accounts for more than 6.6% of our portfolio’s annualized base rent. Our tenants include large and nationally recognized companies such as Amazon.com, Raytheon, JPMorgan Chase, Comcast, Deloitte, Whirlpool, Kellogg’s and Verizon. Approximately 56% of our annualized base rent is derived from investment grade rated tenants. We believe that becoming a publicly traded company is a natural evolution of our company and we have built an organization to make the transition seamlessly. In 2012, we adopted a new name—Chambers Street Properties—and took steps to internalize our management structure. Our process did not involve any substantial change in our senior leadership and was accomplished without any internalization fee paid. We created an integrated operating platform for managing our portfolio that is scalable for the continued growth of our company.

Chambers Street intends to list its shares on the NewYork Stock Exchange (NYSE) continued What Does a Public Listing Mean to You? We expect to list our common shares on the NYSE under the symbol “CSG” on or about May 21, 2013. Upon the listing your shares will be eligible to trade, providing you with the opportunity to buy or sell shares. Of course, we hope you will remain a shareholder with us as we work to grow our portfolio and business. The decision by our board of trustees to list the shares on the NYSE is the result of careful consideration. Based on the current capital market environment, we believe a listing on the NYSE provides a strong platform from which to maximize the value of your shares. Publicly traded real estate companies have enjoyed strong returns in recent years, and companies such as ours that own net lease properties are trading at attractive valuations. Please note, however, that while the listing of your shares on the NYSE is not a taxable event, the sale of your shares could subject you to potential taxes. Please consult your tax and financial advisors for assistance in understanding the tax considerations in the event of a sale of your shares. In conjunction with the listing, we intend to commence a modified “Dutch Auction” tender offer to purchase up to $125 million of our common shares. Under the terms of the proposed tender offer, Chambers Street intends to select the lowest price, within a range of $10.10 per share and $10.60 per share, net to the tendering shareholder in cash, less any applicable withholding taxes and without interest, which would allow the Company to purchase up to the full $125 million of its common shares. We expect to allow shareholders to tender all or a portion of their shares, but if the tender offer is oversubscribed, shares will be accepted on a prorated basis. Chambers Street expects to commence the proposed tender offer on or about May 21, 2013 in conjunction with the listing of its common shares on the NYSE. As a publicly traded company, our board of trustees has determined that the Company will pay a quarterly distribution to its shareholders, reflecting an annual payment of $0.50 per common share, beginning with the third quarter ending September 30, 2013. The Company anticipates that the third quarter distribution of $0.125 per common share will be paid on October 11, 2013 to all shareholders of record on September 26, 2013. Chambers Street believes this dividend level is competitive with dividend payments declared by other publicly traded real estate companies, and provides an appropriate level of retained capital to support the Company’s growth strategies. For further information about our anticipated listing on the NYSE, we refer you to our public filings with the SEC available at www.sec.gov. In addition, we encourage you to contact your financial advisor or our investor services group at (855) 450-0288 for any assistance you may require. A New Platform for Growth Let me assure you that as a publicly traded company, Chambers Street will continue with the same management team and the same disciplined approach to acquiring and managing high-quality, income-producing commercial real estate. We still believe the keys to success are acquiring the right properties at reasonable prices, leasing our buildings to a diversified mix of creditworthy companies and giving those businesses every incentive to stay with us by being highly responsive to their needs. We intend to maintain a strong balance sheet, with ample liquidity and access to multiple sources of capital that we expect a listing will provide. We remain committed to growing Chambers Street as a premier real estate company, and hope you will remain our partner as a shareholder for many years to come. Thank you for your continued confidence and support.
