Overview

About 12 Clos Llewellyn

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

12 Clos Llewellyn is a four-bedroom detached house in Taffs Well, Cardiff, Cardiff (CF15 7AT). It has a recorded floor area of 92 m² (around 990 sq ft), construction records dating it to 2007-2011 and council tax band E. The latest certificate (April 2025) shows a C (score 78), near the top of the C band. The recommended improvements would push it to B (score 89).

It hasn't traded since July 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales.
