Overview

About 23 Garth Olwg

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

23 Garth Olwg is a three-bedroom end-of-terrace house in Gwaelod-Y-Garth, Cardiff, Cardiff (CF15 9HW). It has a recorded floor area of 157 m² (around 1690 sq ft), construction records dating it to 1950-1966 and council tax band E. The latest certificate (March 2013) shows an E (score 50), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 77), a 2-band jump. The latest certificate is from March 2013, so improvements made since then won't be reflected.

At 157 m² the property is well over the postcode median (81 m² across 18 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 89% of similar EPCs). Across 1997–2013, sale prices on this property compounded at 8.7% per year. Today's modelled estimate of £373,000 sits 62.2% above the 2013 sale of £230,000. On a £-per-square-foot basis, the last sale (£136/sq ft) was about 33.5% below the postcode norm. Last sold in November 2013, so it's been off the market for around 13 years.
