4 The Hophouse, St Mary Street, Cardiff, CF10 1FD
About 4 The Hophouse
4 The Hophouse is a one-bedroom semi-detached house in Cardiff (CF10 1FD). It has a recorded floor area of 53 m² (around 570 sq ft), construction records dating it to 2003-2006 and council tax band E. The latest certificate (August 2025) shows a D (score 61), on the cusp of jumping into the C band. Earlier certificates rated it B (October 2014); the latest reading is 2 bands lower. Between certificates, wall efficiency dropped from Very Good to Good and window efficiency dropped from Good to Average. The recommended improvements would push it to C (score 79). Main heating runs on electricity. At 53 m² this is the 4th smallest of 6 units on EPC record in the building, where floor areas span 48–74 m². The building's EPC ratings span E to B across 6 units on file. Other recorded features include outbuildings.
Today's modelled estimate of £144,000 is 12.6% below the 2003 sale of £164,750, an unusual pattern given regional price growth and worth checking against the EPC condition. On a £-per-square-foot basis, the last sale (£289/sq ft) was about 28.6% above the typical sold price in the postcode. It hasn't traded since November 2003, a hold of 23 years that's notably long for the area.
