The house is a frame structure, covered with white wooden clapboards, anchored to a stone foundation. The Priestleys built their home out of wood, dried in trenches on the site, because no stone or brick was available in the area. Joseph wrote a detailed description of the drying process, concluding: "A house constructed with such boards I prefer to one of brick and stone". This may have prompted journalist William Cobbett to caustically label the house a "shed" in one of his political tirades against Joseph. The central section of the house has a slate gable roof with a railing-enclosed deck. The house has "three internal gable end chimneys, one for the main kitchen", and one each at the north and south ends of the central section.
