Overview

About St Lythans House

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

St Lythans House is a detached house in Cardiff (CF5 6BQ). It has a recorded floor area of 209 m² (around 2250 sq ft) and construction records dating it to before 1900. The latest certificate (June 2015) shows an F (score 27), near the bottom of the EPC scale. The recommended improvements would lift it to B (score 88), a 4-band jump. Main heating runs on house coal. The latest certificate is from June 2015, so improvements made since then won't be reflected.

Untraded for 17 years, with the last transfer in August 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £701,000 sits 66.9% above the 2009 sale of £420,000.
