A seventeenth-century stone free house in the small village of Oasby, south of Sleaford, with oak beams and thick walls behind a plain frontage. It takes its name from Sir John Houblon, a local landowner who became the first governor of the Bank of England; the building itself is said to date from around 1650. Worth checking it’s open before making a trip, as its trading has been on and off of late.
