About Osborne House
Osborne House is a mid-terrace house in Laugharne, Carmarthen, Carmarthen (SA33 4QE). It has a recorded floor area of 206 m² (around 2217 sq ft) and construction records dating it to 1900-1929. The latest certificate (December 2025) shows an E (score 51), well below the UK norm with real room to improve. The rating has held steady at E across 2 certificates since September 2009. Between certificates, wall efficiency went from Very Poor to Poor and roof efficiency went from Good to Very Good; while lighting dropped from Very Good to Average. The recommended improvements would lift it to C (score 72), a 2-band jump. Main heating runs on oil. This certificate was lodged in the last six months, so the rating reflects current condition.
It hasn't traded since November 1997, a hold of 29 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. At 206 m² the property is well over the postcode median (100 m² across 17 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £330,000 sits 560% above the 1997 sale of £50,000. On a £-per-square-foot basis, the last sale (£23/sq ft) was about 85% below the postcode norm. 2 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved.
