Window Restoration

The James A. Jr. and Florence Sloane Burden House at 7 East 91st Street and the Otto and Addie Kahn House at 1 East 91st Street (corner of Fifth Avenue) are located in the Carnegie Hill neighborhood of Manhattan.  The Beaux Arts style Burden House, built between 1902 and 1905, was designed by the architectural firm of Warren & Wetmore.  British architect J. Armstrong Stenhouse with associate architect C.P.H. Gilbert designed the Italian Renaissance style Kahn House which was built in 1913-1918.  The two houses were converted to a private school for girls known as the Convent of the Sacred Heart in 1934 and remains under their ownership today.  The school has an enrollment of approximately 600 students ranging from pre-K through 12th grade. 

Easton Architects has performed a detailed window survey for the 320 windows of both structures.  Phases 1 through 7 are in progress and include the restoration of the leaded glass windows of the Chapel and Library spaces located in the Kahn House.  The configuration of the windows is quite unique and complex.  The casement windows are leaded glass units in a wood sash with a leaded glass and wood framed transom panel above.  Within the casement sash, which is 9'-5" high, there is a smaller leaded glass casement unit.  Overall there are 83 different window types.

Both structures are local New York City Landmarks and sit within the Carnegie Hill Historic District. They are listed on the State and National Registers of Historic Places.
