Overview

About 9 Parc Castell Y Mynach

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

9 Parc Castell Y Mynach is a four-bedroom detached house in Creigiau, Cardiff, Cardiff (CF15 9NU). It has a recorded floor area of 145 m² (around 1561 sq ft), construction records dating it to 1967-1975 and council tax band G. The latest certificate (October 2015) shows a D (score 60), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since May 2009. Between certificates, roof efficiency dropped from Good to Very Poor. The recommended improvements would push it to C (score 76).
