In the 1980s, Gubay paid for a replacement church at the site of St Anthony's in Onchan, Isle of Man. The church was designed by Clayton/Massey, with local Architect John Cryer responsible for the interior, and Gubay's suggestion of a window illustrating Christ walking on Douglas Bay by Chris Spittall as a focal point. In 1990, Gubay paid for an extension to Our Lady of the Nativity church in Leixlip, County Kildare, in memory of his mother, Mary Clarke, a native of the area.
