Phipps Houses, ca. 1905.

In the early part of the twentieth century, the entire block span between First and Second Avenues on East 31st Street was the site of the Phipps Houses. Completed in 1906 and designed by Grosvenor Atterbury, the building was commissioned by steel magnate Henry Phipps. Also a philanthropist, the building was Phipps' first attempt to curb the rising tuberculosis epidemic in the city by improving living conditions for paying tenement tenants.

Home to 142 apartments, each unit at the Phipps Houses included two to five rooms, individual bathrooms, and a finished courtyard. Although rent was $14 monthly, which was $4 more expensive than usual tenement rent at the time, the building was designed to maximize the wellbeing of those who would live there. An early brochure said: "This enterprise is not a charity. Tenants are not asked to accept anything free. All that they pay for in their rent they will receive."

Atterbury's design for the Phipps Houses was the first of its kind in the city. The complex was grand and constructed with varied brickwork to maximize airflow. Unlike other tenement buildings, Phipps also designated the bottom floor of his development as space for tenants to receive social services and counsel.
