Y Plas or Plas Buckley was completed in 1872 for the newly titled Sir Edmund Buckley. The house was a grandiose Tudor or Gothick style mansion with a tall central tower and prominent gables. It was consumed by fire c.1920 and the shell was cleared c.1960.

Gasworks used to light the house and estate buildings were mentioned in The Cambrian News on the 20th April 1900 following a discharge of tar into the Dovey River affecting the fishing, the same issue was reported the following year.  The gasworks were marked on the 1887 to 1901 OS maps.
