About 20 Tower Street
20 Tower Street is a three-bedroom semi-detached house in High Wycombe (HP13 5AX). It has a recorded floor area of 78 m² (around 840 sq ft), construction records dating it to 1900-1929 and council tax band C. The latest certificate (September 2017) shows an E (score 54), well below the UK norm with real room to improve. The recommended improvements would lift it to B (score 87), a 3-band jump. Other recorded features include a conservatory.
It hasn't traded since June 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 1999–2009, sale prices on this property compounded at 16.2% per year. Today's modelled estimate of £336,000 sits 92% above the 2009 sale of £175,000. One planning record on file: an extension approved in 2013. Past consents include an extension, meaningful when judging how the property has evolved. It lags the bulk of the postcode on energy efficiency (less efficient than 88% of similar EPCs).
