26 May Street is a five-bedroom semi-detached house in Great Chishill, Royston, Royston (SG8 8SN). It has a recorded floor area of 25 m² (around 271 sq ft), construction records dating it to 1996-2002 and council tax band G. It is a listed building, which means external alterations are tightly controlled but it may qualify for heritage tax reliefs. There is a swimming pool on the plot, uncommon for the area. Other recorded features include a self-contained annexe. Period features are noted in the property record. The latest certificate (December 2011) shows a D (score 66), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 73). Main heating runs on oil. The latest certificate is from December 2011, so improvements made since then won't be reflected.
Today's modelled estimate of £1,117,000 sits 53% above the 2016 sale of £730,000. On a £-per-square-foot basis, the last sale (£2,698/sq ft) was about 877.1% above the typical sold price in the postcode. 15 planning records sit against the property, 14 approved, 1 refused. The record references listed-building consent, which constrain future alterations. At 25 m² it sits well below the postcode median (103 m² across 6 EPCs), making it one of the more compact homes locally. 10 years since the last transfer (October 2016).
