A detached, cylindrical Tudor tower stands immediately to the south-west of the house, and is generally considered to be the earliest part of the building; however, Lysons believes it to have been a later addition. The tower is built of local red brick, and is tall, with walls thick. In 2006, excavations revealed that it continues for some distance below the current ground level. It was described in 1829 as being over a deep well, and being used as a dairy.
