About 9 Cornwall Avenue
9 Cornwall Avenue is a five-bedroom semi-detached house in Welling (DA16 2PR). It has a recorded floor area of 94 m² (around 1012 sq ft), construction records dating it to 1930-1949 and council tax band E. It has already been extended once and our model flags further extension potential, a sign of buyer flexibility. The latest certificate (July 2013) shows a D (score 56), a step below the typical UK home. The recommended improvements would lift it to B (score 82), a 2-band jump. The latest certificate is from July 2013, so improvements made since then won't be reflected.
