Overview

About 12 Llewelyn Goch

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

12 Llewelyn Goch is a five-bedroom detached house in St. Fagans, Cardiff, Cardiff (CF5 6HR). It has a recorded floor area of 174 m² (around 1873 sq ft), construction records dating it to 2003-2006 and council tax band G. The latest certificate (February 2016) shows a D (score 57), a step below the typical UK home. Earlier certificates rated it C (January 2010); the latest reading is one band lower. Between certificates, lighting went from Average to Good; while wall efficiency dropped from Good to Poor and hot-water efficiency dropped from Good to Average. The recommended improvements would lift it to B (score 83), a 2-band jump. The latest certificate is from February 2016, so improvements made since then won't be reflected. Other recorded features include a conservatory.

It hasn't traded since September 2010, a hold of 16 years that's notably long for the area. Across 2002–2010, sale prices on this property compounded at 4.6% per year.
