Sara Delano Roosevelt and Franklin and Eleanor Roosevelt Houses ARCHITECT: Charles A. Platt DATE: 1907-08 STYLE: Georgian This dignified Georgian-style double townhouse was designed by Charles A. Platt and built in 1907-08. The residence was commissioned by Sara Delano Roosevelt, with No. 47 to be occupied by her and No. 49 by her son and daughter-in-law Franklin and Eleanor Roosevelt, and their family. The design of the house is similar to Nos. 6 and 8 East Seventy-Sixth Street, the Ludlow-Parish houses, where, in 1905, Eleanor had been given in marriage to her cousin Franklin by her uncle, President Theodore Roosevelt.
