The below graph shows the average detached house price in the Windsor and Maidenhead local authority area over time, sourced from the HPI. The two 15B ADDINGTON CLOSE sales from December 2014 and March 2025 have been plotted on the graph.

For example, the December 2014 sale was for 34% below the HPI. So the extrapolation line tracks at 34% below the HPI over time, until the March 2025 sale, where it falls to 46% below the HPI.
