15 Dolphin Road is a three-bedroom end-of-terrace house in Birmingham (B11 3LS). It has a recorded floor area of 78 m² (around 840 sq ft), construction records dating it to 1900-1929 and council tax band A. The latest certificate (November 2013) shows an E (score 39), well below the UK norm with real room to improve. The rating has held steady at E across 3 certificates since December 2009. Between certificates, window efficiency dropped from Good to Average and lighting dropped from Good to Very Poor. The recommended improvements would lift it to C (score 77), a 2-band jump.

Held since July 1999 — that's 27 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. Today's modelled estimate of £159,000 sits 430% above the 1999 sale of £30,000. On a £-per-square-foot basis, the last sale (£36/sq ft) was about 63.8% below the postcode norm. At 78 m² it's 15.7% smaller than the typical home in the postcode (93 m² median across 26 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 73% of similar EPCs).
