Gotham House was built in the early 18th century by clothing merchant and Mayor of Tiverton George Davey (1690–1746).

It was one of a number of buildings rebuilt in Tiverton following a fire of 1731, making it a rare example of an elaborate Georgian townhouse. The house remained in the Davey family for a few generations, passing to George Davey's son Roger after his death, and then to his brother George. It then became the property of George's daughter and son-in-law, Captain John and Bridget Hamilton. George In the 1880s, Major Poyntz, Chief Constable of Essex, resided at Gotham House. Since 1960, the building has served as offices of law firm Ashford's Solicitors. The house was restored in 1966 by architects Clement Toy and Raymond Erith. It has occasionally been opened to the public since then.
