Apartment 4, 5 Portland Square, Carlisle, CA1 1AG
About Apartment 4
Apartment 4 is an end-of-terrace house in Carlisle (CA1 1AG). It has a recorded floor area of 126 m² (around 1356 sq ft) and construction records dating it to before 1900. At 126 m² this is the 3rd smallest of 4 units on EPC record in the building, where floor areas span 79–195 m². The building's EPC ratings span E to C, with this unit at the bottom. The latest certificate (August 2021) shows an E (score 49), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 73), a 2-band jump. Main heating runs on electricity.
Today's modelled estimate of £200,000 is 32.2% below the 2021 sale of £295,000, below the original sale price, which typically signals condition or completion-status changes worth verifying. On a £-per-square-foot basis, the last sale (£218/sq ft) was about 25.6% below the postcode norm. At 126 m² the property is well over the postcode median (70 m² across 8 EPCs), placing it in the larger end of the local stock. Sold December 2021 for £295,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend. One historical planning record sits against the property in 2022.
