Overview

About 11 Crystal Avenue

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

11 Crystal Avenue is a four-bedroom semi-detached house in Cardiff (CF23 5QJ). It has a recorded floor area of 57 m² (around 610 sq ft), construction records dating it to 1930-1949 and council tax band F. The latest certificate (February 2010) shows an E (score 52), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 70), a 2-band jump. The latest certificate is from February 2010, so improvements made since then won't be reflected.

Today's modelled estimate of £468,000 sits 87.2% above the 2011 sale of £250,000. On a £-per-square-foot basis, the last sale (£410/sq ft) was about 70.8% above the typical sold price in the postcode. At 57 m² it sits well below the postcode median (98 m² across 11 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 82% of similar EPCs). One planning record on file: an extension approved in 2019. Past consents include an extension and partial demolition, meaningful when judging how the property has evolved. On the market in October 2011 and unlisted since — roughly 15 years.

Valuation method in detail
How the estimate is made
The estimate for 11 Crystal Avenue is modelled from its 57 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF23 5QJ. 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. 1 sale is recorded for 11 Crystal Avenue. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
Reading the EPC
Energy Performance Certificates rate homes from A (most efficient) to G and last 10 years. The latest one for 11 Crystal Avenue was lodged in February 2010 at band E and expired in February 2020, so a new one is needed to sell or let. Floor area, heating and insulation details on this page come from it.
Planning records
Planning applications are collected from local authority registers through PlanIt. 1 application is matched to 11 Crystal Avenue. 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 18 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from CF23 5QJ.
Council tax band
11 Crystal Avenue is in council tax band F. 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.
