THE KNOLL Price Paid vs. HPI Average

The below graph shows the average detached house price in the South Gloucestershire local authority area over time, sourced from the HPI. The two THE KNOLL sales from May 1998 and December 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 May 1998 sale was for 122% above the HPI. So the extrapolation line tracks at 122% above the HPI over time, until the December 2020 sale, where it falls to 86% above the HPI. The line then continues to track at 86% above the HPI.

What might THE KNOLL be worth now?

THE KNOLL might now be worth an estimated £1,049,411.

This is based on house price inflation of 20.6%, between December 2020 and February 2025, for detached houses, in the South Gloucestershire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 20.6% inflationary increase is applied to the most recent sale price for THE KNOLL of £870,000 on 21st December 2020. For the value to have increased from £870,000 to £1,049,411 over the five years and ten months to February 2025, the following assumptions must hold true:

• The value of THE KNOLL has moved in line with the HPI for detached houses in the South Gloucestershire local authority area.
• The December 2020 sale price of £870,000 represented a fair market value for the property.
• The size, condition, and specification of THE KNOLL has not materially changed since December 2020.
