Overview

About 11 The Avenue

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

11 The Avenue is a five-bedroom detached house in Llandaff, Cardiff, Cardiff (CF5 2LP). It has a recorded floor area of 206 m² (around 2217 sq ft), construction records dating it to 1930-1949 and council tax band H. The latest certificate (July 2013) shows an E (score 51), well below the UK norm with real room to improve. Earlier certificates rated it D (March 2013); the latest reading is one band lower. Between certificates, roof efficiency went from Very Poor to Poor, window efficiency went from Poor to Good and lighting went from Very Poor to Good. The recommended improvements would lift it to C (score 70), a 2-band jump. The latest certificate is from July 2013, so improvements made since then won't be reflected. Other recorded features include a conservatory. Period features are noted in the property record. Our model identifies extension potential, subject to local planning policy.

At 206 m² the property is well over the postcode median (95 m² across 11 EPCs), placing it in the larger end of the local stock. One planning record on file: an extension approved in 2016. Past consents include an extension and partial demolition, meaningful when judging how the property has evolved. Last sold in May 2015, so it's been off the market for around 11 years. Today's modelled estimate of £1,024,000 is 42.2% above the 2015 sale price.

How to read this page

Where every figure above comes from, how current it is and what it can't tell you.
Valuation method in detail
How the estimate is made
The estimate for 11 The Avenue is modelled from its 206 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF5 2LP. 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 The 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 The Avenue was lodged in July 2013 at band E and expired in July 2023, so a new one is needed to sell or let. 2 certificates are on record, which shows how the home has changed.
Planning records
Planning applications are collected from local authority registers through PlanIt. 1 application is matched to 11 The 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 16 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from CF5 2LP.
Council tax band
11 The Avenue is in council tax band H. 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.
