About 22 Portlock Road
22 Portlock Road is a three-bedroom mid-terrace house in Maidenhead (SL6 6DZ). It has a recorded floor area of 101 m² (around 1087 sq ft), construction records dating it to 1900-1929 and council tax band D. It is a listed building, which means external alterations are tightly controlled but it may qualify for heritage tax reliefs. Period features are noted in the property record. Our model identifies extension potential, subject to local planning policy. The latest certificate (January 2016) shows a D (score 61), on the cusp of jumping into the C band. When first surveyed in July 2010 the rating was E, the property has climbed 1 band since. Between certificates, hot-water efficiency went from Poor to Good, lighting went from Poor to Good and main heating went from Average to Good. The recommended improvements would push it to C (score 79). The latest certificate is from January 2016, so improvements made since then won't be reflected.
Most recent transfer: February 2019 at £485,000. Across the public record there are 5 sales, relatively high churn for a single property. 2 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension and a loft conversion, meaningful when judging how the property has evolved. At 101 m² it's 18.8% larger than the typical home in the postcode (85 m² median across 38 EPCs). Across 1999–2019, sale prices on this property compounded at 6.3% per year.
