KZLA was engaged in early 2015 to join the team of preservation and conservation experts to assess the existing conditions and document the history of the United States Embassy in Delhi. This is the fourth property on the Secretary of State's Register of Culturally Significant Properties which KZLA staff has researched, documented, and assessed for the Department of State.

The U.S. Embassy in new Delhi was designed by famed modernist architect Edward Durell Stone in the 1950s under President Dwight D. Eisenhower. The two compound complex includes the Chancery, the Ambassador's residence, and the American School. Located within the diplomatic enclave designed by Edwin Lutyens known as Chanakyapuri.

The Embassy compound containing the Ambassador's residence and the Chancery was undergoing a master planning and design effort by OBO when the Historic Structures Report (HSR) was deemed necessary to guide further design efforts. Documentation and recommendations were prepared in consideration of The Secretary of the Interior's Standards for the Treatment of Historic Properties with Guidelines for the Treatment of Cultural Landscapes for the report and Historic American Landscape Survey (HALS) Level II standards for the plan drawings. Significant to the redevelopment of the compound, was identifying the character-defining features of the landscape and documenting the 2015 conditions prior to development which began in 2018.
