The original National School and associated house at Llandegfan were built in 1832 and a plaque in the wall to the left of the porch commemorates a donation given by the Duchess of Kent in the same year. A plaque over the entrance porch notes that the school was restored in about 1901 in memory of Queen Victoria. It is constructed in uncoursed rubble with a low pitched roof and sash windows. The house has two storeys.
