At 105 m² the property is well over the postcode median (51 m² across 38 EPCs), placing it in the larger end of the local stock. 14 planning records sit against the property, 9 approved, 4 refused. Past consents include change of use to residential, subdivision and an extension, meaningful when judging how the property has evolved. Sold June 2021 for £750,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
