Get started1 King Street is a five-bedroom detached house in Earls Barton, Northampton, Northampton (NN6 0LQ). It has a recorded floor area of 177 m² (around 1905 sq ft), construction records dating it to before 1900 and council tax band B.

Untraded for 27 years, with the last transfer in March 1999. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time.
