In 1710 Thomas Archer was commissioned to build the existing Chettle House in place of the Elizabethan house then occupied by the Chafin family. It is reputed to have taken some twenty five years to build, all the materials coming from the neighbouring countryside. The house has two principal storeys with basements and attics and it had a cupola which formerly crowned a centre of the house but was removed in the 1840s. The house has no corners, all corners are rounded in common with the Archer style similar to those at the Church in Smith Square in London. Although the south end of the basement is not open to the public the central lower hall illustrates how the house was constructed.
Pillars set in the wall or in the room maintain barrel vaulted ceilings.
Passing from the basement to the Oak Hall , one climbs what was the original stone staircase. Although alterations were made to The Oak or East Hallway in the 1840s the staircase is original. There was a gallery on the east wall connecting the bedrooms. The Stone or West Hall has doorways made of walnut and oak and are probably original but the timpana with bass reliefs by Alfred Stevens were added in the 1840s. The two statues came from the great exhibition of 1851 and the chandelier is reputed to be early English between 1760 and 1780.
