By 1932, the  Second School had been in use for twenty-five years. Now it was badly in need of renovations, and so the residents voted to give the school district $17,000 to purchase the land next door and build a two-room addition to the building. But the population of Brentwood was growing in the 1930s, and over the next few years it became clear that a new school would soon be needed.

In 1935, the Board of Education began four years of intense effort to secure financing for a new school building. Finally, the Board received public approval for a proposition to spend $198,000 on the construction of a new school at a special meeting held on March 31,1939. It was intended to have eight classrooms and accommodate 250 students. Land was purchased on Third Avenue across from the municipal water works. They broke ground on September 25,1939 when Dr. William H. Ross, Chairman of the Board, and Board member Julia A.  Gibney  each removed a spade full of earth.

 The cornerstone was laid at a   special ceremony on May 5,1940  with Second Supervisory District Superintendent Walter M. Ormsby and Dr. Ross addressing the crowd (Ross recalled how he laid the cornerstone of the Second School on October 27,1906, and how the original one-room school was built for $700, while this new one would cost nearly three hundred times as much). The building was dedicated on December 14,1940, with Ormsby reading a prepared speech by William E. Young, Director of Elementary Education of the New York State Department of Education, who could not attend due to illness. Dr. Ross and Principal Leigh P. Stuart also spoke.
