The Frick Collection today unveiled a plan to enhance and renovate its museum and library to further fulfill founder Henry Clay Frick’s long-standing vision to offer public access to its works of art and educational programs. The proposal derives from the Frick’s history of architecturally cohesive expansions and alterations. It includes the construction of a new addition in keeping with the scale and design of the original house and the library wing, and the renovation and expansion of interior spaces added in the 1930s and 1970s. A centerpiece of the new plan will be the opening of the museum’s second floor to the public for the first time. The result will preserve the intimate visitor experience in an extraordinary mansion that has delighted art lovers for nearly eight decades. Davis Brody Bond Architects and Planners, the New York–based firm that was responsible for the 2011 award-winning transformation of an exterior loggia into the museum’s Portico Gallery, will design the project.
