DERWEN is a large extended detached house of 113m², built sometime between 1967 and 1975, which could now be worth an estimated £266,893.

The most recent EPC inspection was October 2010, where the current energy rating was D, and the potential energy rating was C.
Land registry data shows two sales for DERWEN since 1st January 1995. The below table shows the price paid for the two sales, along with the average detached price in the Powys local authority area for the corresponding sale date. Both of the two DERWEN sales were for below the average price. The average price is sourced from the Office for National Statistics' House Price Index (HPI).
Date | Price | HPI Price | Variation from HPI |
---|---|---|---|

The below graph shows the average detached house price in the Powys local authority area over time, sourced from the HPI. The two DERWEN sales from September 2011 and February 2017 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 September 2011 sale was for 18% below the HPI. So the extrapolation line tracks at 18% below the HPI over time, until the February 2017 sale, where it rises to 15% below the HPI. The line then continues to track at 15% below the HPI.
DERWEN might now be worth an estimated £266,893.
This is based on house price inflation of 36.9%, between February 2017 and December 2024, for detached houses, in the Powys local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 36.9% inflationary increase is applied to the most recent sale price for DERWEN of £195,000 on 3rd February 2017. For the value to have increased from £195,000 to £266,893 over the six years and two months to December 2024, the following assumptions must hold true:
