Overview

About 18a

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

18a is a two-bedroom semi-detached house in Port Tennant, Swansea, Swansea (SA1 8NX). It has a recorded floor area of 134 m² (around 1442 sq ft), construction records dating it to 1900-1929 and council tax band A. The latest certificate (July 2015) shows a C (score 73). The recommended improvements would push it to B (score 84). The latest certificate is from July 2015, so improvements made since then won't be reflected.

Held since January 2007 — that's 19 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 134 m² the property is well over the postcode median (77 m² across 28 EPCs), placing it in the larger end of the local stock. Its energy rating outperforms most of the postcode (better than 71% of similar EPCs). Today's modelled estimate of £132,000 sits 200% above the 2007 sale of £44,000. On a £-per-square-foot basis, the last sale (£31/sq ft) was about 63.4% below the postcode norm. 2 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension, meaningful when judging how the property has evolved.
