The Lagmore housing estate lies to the south of Poleglass, in the Derriaghy area of Lisburn. Lagmore is a more recent development than Poleglass or Twinbrook and indeed as of 2012 houses are still being built on the estate. Its Catholic church, Christ the Redeemer, was only created as a breakaway parish from St Luke's Twinbrook in 1997 whilst the local primary school of the same name dates to only 1999.Christ the Redeemer Primary School
