In 1921, the Catholic Diocese of Hartford purchased a Federal style farmhouse with 135-acres of land in Ashford, Connecticut, with the intention of establishing a new parish in the area. The Diocese assigned Father William J. Dunn, a Connecticut native and son of Irish Immigrants, to this daunting task. Since they had no church building at the time, Father Dunn partitioned off a section of his own home to serve as a chapel for about 100 worshipers, until the purpose-built St. Philip the Apostle Church was constructed in the 1930s. Father Dunn convinced summer resident Paul Chalfin to design the new building. Chalfin was not an architect, but he was an architectural designer whose best known building is the Villa Vizcaya in Miami, Florida. Chalfin was openly gay, and his hiring by the Catholic Church to design one of its churches in the 1930s is noteworthy. There were certainly several Irish immigrants and people of Irish descent in the congregation, but many parishioners came from small villages in Slovakia. The dome is a typical feature of churches in those villages and Chalfin included it in his design as a tribute to them. Due to material and construction costs during the Great Depression, members of the church largely built the church themselves with rocks acquired from stone walls and farms nearby. The church was completed in 1937.
