Castle House is a house in Bridgwater, Somerset, England. Castle House is associated with two important Sedgemoor families, the Boards and the Ackermans; John Board (1802-1861) who extended his family's brick company into cement in 1844, and his grandson William Ackerman who joined the company in 1871 and is credited with the first ‘true’ Portland cement.’ Built in 1851 to resemble a Tudor gatehouse, the construction uses panels of prefabricated concrete, with significant further usage of concrete throughout the building.
