About 12 Brunswick Street
12 Brunswick Street is a three-bedroom mid-terrace house in Swansea (SA1 4JR). It has a recorded floor area of 97 m² (around 1042 sq ft), construction records dating it to before 1900 and council tax band C. The latest certificate (January 2009) shows an F (score 32), near the bottom of the EPC scale. The recommended improvements would push it to E (score 49). The latest certificate is from January 2009, so improvements made since then won't be reflected.
It hasn't traded since August 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 97 m² it's 21.9% smaller than the typical home in the postcode (124 m² median across 21 EPCs). On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £178,000 is 36.9% above the 2009 sale price. On a £-per-square-foot basis, the last sale (£125/sq ft) was about 92.2% above the typical sold price in the postcode.
