BOUNDARY HOUSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Windsor and Maidenhead local authority area over time, sourced from the HPI. The four BOUNDARY HOUSE sales between November 2002 and January 2020 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 November 2007 sale was for 126% above the HPI. So the extrapolation line tracks at 126% above the HPI over time, until the January 2020 sale, where it rises to 323% above the HPI. The line then continues to track at 323% above the HPI.

What might BOUNDARY HOUSE be worth now?

This is based on house price inflation of 25.3%, between January 2020 and February 2025, for detached houses, in the Windsor and Maidenhead local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 25.3% inflationary increase is applied to the most recent sale price for BOUNDARY HOUSE of £3,875,000 on 7th January 2020. For the value to have increased from £3,875,000 to £4,857,224 over the four years and eleven months to February 2025, the following assumptions must hold true:
