About 11a
11a is a two-bedroom mid-terrace house in Southwark, London, London (SE17 1LR). It has a recorded floor area of 80 m² (around 861 sq ft), construction records dating it to before 1900 and council tax band C. The latest certificate (May 2014) shows a D (score 62), on the cusp of jumping into the C band. When first surveyed in August 2011 the rating was E, the property has climbed 1 band since. Between certificates, window efficiency went from Very Poor to Average. The recommended improvements would push it to C (score 71). The latest certificate is from May 2014, so improvements made since then won't be reflected. The property has an EV charger on record, all of which lower running costs and tend to lift resale appeal. Period features are noted in the property record.
At 80 m² the property is well over the postcode median (51 m² across 6 EPCs), placing it in the larger end of the local stock. On a £-per-square-foot basis, the last sale (£650/sq ft) was about 75% above the typical sold price in the postcode. Most recent transfer: October 2022 at £560,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
