Overview

About St Edeyrns House

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

St Edeyrns House is a three-bedroom detached house in Cardiff (CF23 6TB). It has a recorded floor area of 106 m² (around 1141 sq ft) and construction records dating it to 1967-1975. At 106 m² this is the largest unit on EPC record across St Edeyrns House (84–106 m²). The building's EPC ratings span E to C, with this unit at the bottom. On EPC score it ranks last in the building (51 versus a best of 74). The latest certificate (April 2015) shows an E (score 51), well below the UK norm with real room to improve. Earlier certificates rated it D (July 2014); the latest reading is one band lower. Between certificates, roof efficiency dropped from Poor to Very Poor. The recommended improvements would lift it to C (score 75), a 2-band jump. The latest certificate is from April 2015, so improvements made since then won't be reflected.

Last sold in May 2017, so it's been off the market for around 9 years. Across the public record there are 5 sales, relatively high churn for a single property. It lags the bulk of the postcode on energy efficiency (less efficient than 88% of similar EPCs). Across 2001–2017, sale prices on this property compounded at 5.6% per year. Today's modelled estimate of £331,000 is 22.6% above the 2017 sale price. On a £-per-square-foot basis, the last sale (£237/sq ft) was about 17% above the typical sold price in the postcode.
