20 Palace Road, Cardiff, CF5 2AF
About 20 Palace Road
20 Palace Road is a detached house in Cardiff (CF5 2AF). It has a recorded floor area of 311 m² (around 3348 sq ft) and construction records dating it to 1900-1929. The latest certificate (May 2026) shows a D (score 66), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 78). This certificate was lodged in the last six months, so the rating reflects current condition.
Held since September 1996 — that's 30 years off the open market, well above the local norm. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. At 311 m² the property is well over the postcode median (146 m² across 18 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £1,221,000 sits 495.6% above the 1996 sale of £205,000. On a £-per-square-foot basis, the last sale (£61/sq ft) was about 73% below the postcode norm. One planning record on file: new windows approved in 2008. Past consents include new windows, meaningful when judging how the property has evolved.
