About 17 Cowgill Close
17 Cowgill Close is a five-bedroom semi-detached house in Northampton (NN3 8PB). It has a recorded floor area of 81 m² (around 872 sq ft), construction records dating it to 1983-1990 and council tax band B. The latest certificate (August 2013) shows a D (score 66), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 87), a 2-band jump. The latest certificate is from August 2013, so improvements made since then won't be reflected. Records show the property has been extended at some point in its history. The home occupies a cul-de-sac position.
Untraded for 25 years, with the last transfer in March 2001. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time.
