20 Light Buildings is a semi-detached house in Preston (PR1 2RA). It has a recorded floor area of 57 m² (around 614 sq ft), construction records dating it to 2007 onwards and council tax band B. At 57 m² this is the 15th smallest of 64 units on EPC record in the building, where floor areas span 47–87 m². The building's EPC ratings span D to B, with this unit at the bottom. The latest certificate (July 2020) shows a D (score 64), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 80). Main heating runs on electricity.

Today's modelled estimate of £113,000 is 10.3% below the 2009 sale of £126,000, an unusual pattern given regional price growth and worth checking against the EPC condition. On a £-per-square-foot basis, the last sale (£205/sq ft) was about 35.8% above the typical sold price in the postcode. Untraded for 17 years, with the last transfer in July 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. It lags the bulk of the postcode on energy efficiency (less efficient than 78% of similar EPCs).
