About 21a
21a is a three-bedroom end-of-terrace house in Cambridge (CB1 2AX). It has a recorded floor area of 90 m² (around 969 sq ft), construction records dating it to 1900-1929 and council tax band E. The latest certificate (May 2018) shows a D (score 62), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 85), a 2-band jump. Period features are noted in the property record. Records show the property has been extended at some point in its history. The home occupies a cul-de-sac position.
4 planning records sit against the property, 1 approved, 0 refused. Past consents include an extension and a loft conversion, meaningful when judging how the property has evolved. Today's modelled estimate of £916,000 is 22.1% above the 2021 sale price. On a £-per-square-foot basis, the last sale (£774/sq ft) was about 159.7% above the typical sold price in the postcode. At 90 m² it's 19.6% smaller than the typical home in the postcode (112 m² median across 31 EPCs). Most recent transfer: February 2021 at £750,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
