About 103a
103a is a two-bedroom mid-terrace house in Westminster, London, London (SW1V 3QP). It has a recorded floor area of 86 m² (around 926 sq ft), construction records dating it to before 1900 and council tax band F. The latest certificate (June 2016) shows a D (score 67), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since August 2009. Between certificates, lighting dropped from Good to Very Poor. The recommended improvements would push it to C (score 80). At 86 m² this is the 9th smallest of 25 units on EPC record in the building, where floor areas span 46–162 m². The building's EPC ratings span E to C across 25 units on file.
It hasn't traded since December 2009, a hold of 16 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £1,048,000 sits 74.7% above the 2009 sale of £600,000. On a £-per-square-foot basis, the last sale (£648/sq ft) was about 18% below the postcode norm. 2 planning records sit against the property, 2 approved, 0 refused. Past consents include new windows and a basement excavation, meaningful when judging how the property has evolved.
