AI Summary
This is a well-presented, extended semi-detached family home in the highly regarded Radyr area of Cardiff, offering generous floor space of 178m² and a modern interior finish. The asking price of £425,000 sits above the local comp median of around £305,000, though the upper end of comparable sales reaches £450,000, suggesting the premium reflects the extension, renovation quality, and Radyr's desirability. Buyers should verify the EPC rating discrepancy between the listing (C) and register data (E), and factor in the cost of cavity wall insulation to improve energy efficiency.
