About 9 Alexandra Avenue
9 Alexandra Avenue is a five-bedroom detached house in West Mersea, Colchester, Colchester (CO5 8BG). It has a recorded floor area of 247 m² (around 2659 sq ft), construction records dating it to 1900-1929 and council tax band G. The latest certificate (March 2016) shows a D (score 57), a step below the typical UK home. When first surveyed in March 2013 the rating was E, the property has climbed 1 band since. Between certificates, window efficiency went from Poor to Good; while lighting dropped from Good to Very Poor. The recommended improvements would push it to C (score 74). The latest certificate is from March 2016, so improvements made since then won't be reflected. Other recorded features include a conservatory and attached land beyond the plot.
At 247 m² the property is well over the postcode median (150 m² across 20 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £955,000 sits 50.4% above the 2013 sale of £635,000. 2 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved. Last sold in September 2013, so it's been off the market for around 13 years.
