25 Aspen Close is a detached house in Killamarsh, Sheffield, Sheffield (S21 1TA). It has a recorded floor area of 82 m² (around 883 sq ft), construction records dating it to 1991-1995 and council tax band C. The latest certificate (September 2014) shows a D (score 67), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 83), a 2-band jump. The latest certificate is from September 2014, so improvements made since then won't be reflected.
Untraded for 30 years, with the last transfer in August 1996. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £233,000 sits 348.1% above the 1996 sale of £52,000. On a £-per-square-foot basis, the last sale (£59/sq ft) was about 63.5% below the postcode norm. One planning record on file: an extension approved in 2004. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved.
