20 St Phillips Close, Auckland Park, Bishop Auckland, DL14 8BD

20 St Phillips Close is a four-bedroom detached house in Auckland Park, Bishop Auckland, Bishop Auckland (DL14 8BD). It has a recorded floor area of 114 m² (around 1230 sq ft), construction records dating it to 2007 onwards and council tax band D. The latest certificate (February 2009) shows a D (score 68), on the cusp of jumping into the C band. Earlier certificates rated it C (January 2009); the latest reading is one band lower. Between certificates, lighting dropped from Good to Very Poor. The recommended improvements would push it to C (score 74). The latest certificate is from February 2009, so improvements made since then won't be reflected.

It hasn't traded since April 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. One planning record on file: an extension approved in 2007. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved. Across 2007–2009, sale prices on this property compounded at -7% per year. Today's modelled estimate of £213,000 is 36.5% above the 2009 sale price.
