About 1 Idsworth Down
1 Idsworth Down is a semi-detached house in Petersfield (GU31 4BL). It has a recorded floor area of 133 m² (around 1432 sq ft), construction records dating it to 2007 onwards and council tax band E. The latest certificate (April 2016) shows a C (score 70). The rating has held steady at C across 2 certificates since March 2009. Between certificates, lighting went from Average to Very Good; while main heating dropped from Average to Poor. Main heating runs on electricity. The latest certificate is from April 2016, so improvements made since then won't be reflected.
It hasn't traded since May 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. Today's modelled estimate of £687,000 sits 67.6% above the 2009 sale of £410,000. On a £-per-square-foot basis, the last sale (£286/sq ft) was about 28.9% below the postcode norm. 8 planning records sit against the property, 5 approved, 0 refused. Past consents include tree works, an extension and a conservatory, meaningful when judging how the property has evolved. At 133 m² it's 26.3% larger than the typical home in the postcode (105 m² median across 4 EPCs).
