15 TREBLE CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Winchester local authority area over time, sourced from the HPI. The four 15 TREBLE CLOSE sales between June 1996 and August 2023 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the August 2012 sale was for 29% below the HPI. So the extrapolation line tracks at 29% below the HPI over time, until the August 2023 sale, where it rises to 28% below the HPI. The line then continues to track at 28% below the HPI.
