100a is a four-bedroom detached house in New Barnet, Barnet, Barnet (EN4 9QS). It has a recorded floor area of 172 m² (around 1851 sq ft), construction records dating it to 2007 onwards and council tax band G. The latest certificate (June 2015) shows a C (score 73). Earlier certificates rated it B (March 2010); the latest reading is one band lower.

The latest certificate is from June 2015, so improvements made since then won't be reflected.

It hasn't traded since June 2008, a hold of 18 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 172 m² the property is well over the postcode median (122 m² across 14 EPCs), placing it in the larger end of the local stock. 8 planning records sit against the property, 7 approved, 1 refused. Past consents include a garage conversion, an extension, solar panel installation and a conservatory, meaningful when judging how the property has evolved. Across 2007–2008, sale prices on this property compounded at 55% per year. Today's modelled estimate of £1,030,000 is 46.1% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£381/sq ft) was about 21.8% below the postcode norm.
