Overview

About 21 Llewelyn Goch

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

21 Llewelyn Goch is a detached house in St. Fagans, Cardiff, Cardiff (CF5 6HR). It has a recorded floor area of 185 m² (around 1991 sq ft), construction records dating it to 2003-2006 and council tax band G. The latest certificate (March 2016) shows a D (score 57), a step below the typical UK home. The recommended improvements would lift it to B (score 81), a 2-band jump. The latest certificate is from March 2016, so improvements made since then won't be reflected.

It hasn't traded since September 2003, a hold of 23 years that's notably long for the area. Across 2002–2003, sale prices on this property compounded at 1.3% per year. Today's modelled estimate of £536,000 sits 70.2% above the 2003 sale of £315,000. One planning record on file: an extension approved in 2017.

How the estimate is made

It is an automated estimate, not a survey or mortgage valuation: condition, layout and improvements that aren't on record can move the real figure either way.
Where sold prices come from
Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 2 sales are recorded for 21 Llewelyn Goch. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
Reading the EPC

Planning records
Planning applications are collected from local authority registers through PlanIt. 1 application is matched to 21 Llewelyn Goch. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
Area figures
Crime is police-recorded street-level data over the last 16 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from CF5 6HR.
Council tax band
21 Llewelyn Goch is in council tax band G. Bands are set by the Valuation Office Agency from historic values (1 April 1991 in England, 1 April 2003 in Wales), not today's price; the amount you pay depends on the council's rate for the band.
