Land registry data shows two sales for 12 PLAS PENWERN since 1st January 1995. The below table shows the price paid for the two sales, along with the average detached price in the Carmarthenshire local authority area for the corresponding sale date.

The below graph shows the average detached house price in the Carmarthenshire local authority area over time, sourced from the HPI. The two 12 PLAS PENWERN sales from October 2004 and April 2013 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 October 2004 sale was for 4% above the HPI. So the extrapolation line tracks at 4% above the HPI over time, until the April 2013 sale, where it falls to roughly the same level as the HPI. The line then continues to track in line with the HPI.
12 PLAS PENWERN might now be worth an estimated £276,086.
This is based on house price inflation of 67.3%, between April 2013 and February 2025, for detached houses, in the Carmarthenshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 67.3% inflationary increase is applied to the most recent sale price for 12 PLAS PENWERN of £165,000 on 19th April 2013. For the value to have increased from £165,000 to £276,086 over the twelve years and two months to February 2025, the following assumptions must hold true:
