About 4 Ashdown House
4 Ashdown House is a two-bedroom semi-detached house in Guildford (GU1 3LL). It has a recorded floor area of 58 m² (around 624 sq ft) and construction records dating it to 1996-2002. At 58 m² this is the largest unit on EPC record across the building (45–58 m²). On EPC score it ranks first in the building (80 versus a worst of 70). The latest certificate (February 2020) shows a C (score 80), near the top of the C band. Earlier certificates rated it B (March 2009); the latest reading is one band lower. Between certificates, window efficiency went from Average to Good; while lighting dropped from Very Good to Good. The recommended improvements would push it to B (score 81).
It hasn't traded since July 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Across 1995–2009, sale prices on this property compounded at 7.7% per year. Today's modelled estimate of £355,000 sits 54.3% above the 2009 sale of £230,000. 3 planning records sit against the property, 3 approved, 0 refused. Past consents include tree works, meaningful when judging how the property has evolved. The record references conservation-area consent, which constrain future alterations.
