About 1 Sonata House
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
1 Sonata House is a two-bedroom mid-terrace house in Port Solent, Portsmouth, Portsmouth (PO6 4UZ). It has a recorded floor area of 75 m² (around 807 sq ft), construction records dating it to 1996-2002 and council tax band F. The latest certificate (December 2014) shows a D (score 65), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 72). Main heating runs on electricity. The latest certificate is from December 2014, so improvements made since then won't be reflected. Our model identifies extension potential, subject to local planning policy.
On a £-per-square-foot basis, the last sale (£367/sq ft) was about 18.4% above the typical sold price in the postcode. Last sold in June 2015, so it's been off the market for around 11 years.
