About 18 Llwynderw
18 Llwynderw is a four-bedroom detached house in Three Crosses, Swansea, Swansea (SA4 3QG). It has a recorded floor area of 107 m² (around 1152 sq ft), construction records dating it to 1967-1975 and council tax band E. The latest certificate (February 2010) shows a D (score 65), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 70). The latest certificate is from February 2010, so improvements made since then won't be reflected. Other recorded features include a conservatory.
It hasn't traded since October 2001, a hold of 25 years that's notably long for the area. Today's modelled estimate of £326,000 sits 226% above the 2001 sale of £100,000. On a £-per-square-foot basis, the last sale (£87/sq ft) was about 28.3% below the postcode norm. One planning record on file: an extension approved in 2006. Past consents include an extension, meaningful when judging how the property has evolved.
