About 12 Hamburg House
12 Hamburg House is a one-bedroom end-of-terrace house in Portsmouth (PO1 3GG). It has a recorded floor area of 59 m² (around 635 sq ft), construction records dating it to 2003-2006 and council tax band B. The latest certificate (December 2025) shows a C (score 75), near the top of the C band. The rating has held steady at C across 2 certificates since March 2016. Between certificates, lighting went from Very Poor to Good; while window efficiency dropped from Good to Average. Main heating runs on electricity. This certificate was lodged in the last six months, so the rating reflects current condition. At 59 m² this is the 15th smallest of 34 units on EPC record in the building, where floor areas span 36–69 m². The building's EPC ratings span D to B across 34 units on file.
Untraded for 18 years, with the last transfer in February 2008. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. On a £-per-square-foot basis, the last sale (£260/sq ft) was about 18% below the postcode norm.
