Get startedUnicorn House is a semi-detached house in Bowes, Barnard Castle, Barnard Castle (DL12 9HL). It has a recorded floor area of 140 m² (around 1507 sq ft), construction records dating it to before 1900 and council tax band B. The latest certificate (February 2026) shows an E (score 39), well below the UK norm with real room to improve. When first surveyed in October 2013 the rating was F, the property has climbed 1 band since. Between certificates, wall efficiency went from Very Poor to Poor, roof efficiency went from Average to Very Good and lighting went from Very Poor to Poor; while window efficiency dropped from Average to Poor. The recommended improvements would lift it to C (score 74), a 2-band jump. Main heating runs on electricity. This certificate was lodged in the last six months, so the rating reflects current condition.
At 140 m² the property is well over the postcode median (104 m² across 4 EPCs), placing it in the larger end of the local stock. 13 planning records sit against the property, 10 approved, 3 refused. Past consents include an extension and new windows, meaningful when judging how the property has evolved. The record references listed-building consent, which constrain future alterations. Today's modelled estimate of £201,000 is 43.6% above the 2014 sale price. On a £-per-square-foot basis, the last sale (£93/sq ft) was about 18.8% below the postcode norm. Last sold in November 2014, so it's been off the market for around 12 years.
