About 3 Adele Avenue
3 Adele Avenue is a four-bedroom detached house in Welwyn (AL6 0AU). It has a recorded floor area of 130 m² (around 1399 sq ft), construction records dating it to 1967-1975 and council tax band G. The latest certificate (August 2016) shows a D (score 63), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 83), a 2-band jump. The home occupies a corner plot.
At 130 m² the property is well over the postcode median (69 m² across 15 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 80% of similar EPCs). 5 planning records sit against the property, 3 approved, 1 refused. Past consents include tree works and an extension, meaningful when judging how the property has evolved. Today's modelled estimate of £1,135,000 is 26.1% above the 2016 sale price. On a £-per-square-foot basis, the last sale (£643/sq ft) was about 179.3% above the typical sold price in the postcode. Last sold in December 2016, so it's been off the market for around 9 years.
