18 Admiralty Tower, Queen Street, Portsmouth, PO1 3GA

18 Admiralty Tower is a one-bedroom mid-terrace house in Portsmouth (PO1 3GA). It has a recorded floor area of 42 m² (around 452 sq ft), construction records dating it to 2003-2006 and council tax band C. The latest certificate (August 2019) returns a high B (score 85), putting the home a stone's throw from an A rating. The rating has held steady at B across 2 certificates since September 2009. Between certificates, lighting went from Very Poor to Good. Main heating runs on electricity. At 42 m² this is the 10th smallest of 62 units on EPC record in the building, where floor areas span 27–93 m². The building's EPC ratings span D to B, with this unit at the top.

It hasn't traded since June 2008, a hold of 18 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 42 m² it sits well below the postcode median (63 m² across 61 EPCs), making it one of the more compact homes locally. On a £-per-square-foot basis, the last sale (£419/sq ft) was about 18% above the typical sold price in the postcode.
