The below graph shows the average terraced house price in the West Northamptonshire local authority area over time, sourced from the HPI. The four 11A THE SQUARE sales between April 1998 and February 2022 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 July 2015 sale was for 196% above the HPI. So the extrapolation line tracks at 196% above the HPI over time, until the February 2022 sale, where it rises to 258% above the HPI. The line then continues to track at 258% above the HPI.

11A THE SQUARE might now be worth an estimated £845,123.
This is based on house price inflation of 9.4%, between February 2022 and August 2025, for terraced houses, in the West Northamptonshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 9.4% inflationary increase is applied to the most recent sale price for 11A THE SQUARE of £772,500 on 2nd February 2022. For the value to have increased from £772,500 to £845,123 over the two years and six months to August 2025, the following assumptions must hold true:
