Description
Blenheim House is a Grade II listed building located on Chilkwell Street, set back in a garden. It dates from the early 19th century and is two storeys high. The house features a hipped slate roof with one small dormer and a plain eaves band. The front is divided by flat pilasters and has a stringcourse. There are four first-floor windows set in sunk panels with semicircular heads, and two ground-floor windows in similar panels with segmental heads. The windows are sashes with thin glazing bars. The round-headed doorway is flanked by quarter-columns at the angle of the reveals and has a semi-circular fanlight with tracery above a six-panel door. There is a second door to the left, and a later one-storey extension is present on the right. Blenheim House is part of a group that includes Nos 3 and 5, as well as other listed buildings from No 3 to No 17 on the north-east side, Glastonbury Abbey, Abbey House, and the wall surrounding the grounds of the Abbey and Abbey House, all of which form an important group.
