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 £993,000 is 37.9% above the 2015 sale price.
