Monaghan Bishop's House is a handsome, if somewhat severe, building that retains its architectural integrity impeccably. The survival and excellent condition of intrinsic architectural features and fabric is testament to the quality and dedication with which they were designed and executed, as well as to the respect and care afforded to the building in the century since its construction. The building is also significant as part of a group with the architectural style and fabric of the house reflecting the quality of the other structures. The fine carved stone detailing adds an artistic quality to the property and serves as a quality example of the refined stonemasonry skills which were present in Ireland particularly towards the end of the nineteenth century and which often survive best in buildings of this type. The stained glass by Michael Healy is also notable.
