Land registry data shows three sales for PHILADELPHIA HOUSE since 1st January 1995. The below table shows the price paid for the three sales, along with the average detached price in the Newport local authority area for the corresponding sale date. All of the three PHILADELPHIA HOUSE sales were for above 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 |
---|---|---|---|
2017 9 MAR | £650,000 | £257,183 | ![]() 153% above HPI |

The below graph shows the average detached house price in the Newport local authority area over time, sourced from the HPI. The three PHILADELPHIA HOUSE sales between July 2007 and March 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 November 2013 sale was for 147% above the HPI. So the extrapolation line tracks at 147% above the HPI over time, until the March 2017 sale, where it rises to 153% above the HPI. The line then continues to track at 153% above the HPI.
PHILADELPHIA HOUSE might now be worth an estimated £988,586.
This is based on house price inflation of 52.1%, between March 2017 and February 2025, for detached houses, in the Newport local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 52.1% inflationary increase is applied to the most recent sale price for PHILADELPHIA HOUSE of £650,000 on 9th March 2017. For the value to have increased from £650,000 to £988,586 over the eight years and one month to February 2025, the following assumptions must hold true:
