The farmstead's 1808 springhouse and mid-nineteenth century barn, together with the setting well off the road, are said to reflect the evolution of central Bucks County farmsteads and its period of significance.","narrative":"Set in a thirty-one acre tract in rural Buckingham Township, Bucks County, the Gilbert farmstead is built around a stone farmhouse begun in 1711 by Thomas Gilbert. The house grew in stages: a two-and-a-half story, three-bay stone block with segmental arches and datestones, a 1735 section added to its west gable, and a later kitchen wing carrying a datestone of 1812. A stone springhouse dated 1808 contains a corner fireplace and a second-floor room, reflecting its use as a milk house with lodging rooms. A mid-nineteenth century frame and stone bank barn and a wagon house of about 1840 complete the group. The Gilbert family held the land from before 1707, and later owners included the Worthingtons and Shepherds. The house is regarded as a representative example of regional farmhouse building, and the farm's preserved buildings and open fields keep its historic character intact.","period_of_significance":"1735-ca. 1840","architect_builder":"Thomas Gilbert (builder of the 1711 and 1735 sections of the house); G.
