About Flat
Flat is a semi-detached house in Southsea (PO5 3BY). It has a recorded floor area of 236 m² (around 2543 sq ft), construction records dating it to 1900-1929 and council tax band B.

The recommended improvements would push it to D (score 61). The latest certificate is from June 2009, so improvements made since then won't be reflected.
