A locality in Cardiff.
Sold house prices in Bonvilston have an overall average of £605,512, based on all 130 residential sales on record — drawn from every recorded UK house sale.
Medians over the most recent 12 months of all UK property sales (to December 2025). Median is used, not mean — it isn't skewed by the odd very-high sale.
Across Bonvilston, the median sold price over the 12 months to December 2025 was £688,000 — it rose 105.4% on the year before. That reflects 21 recorded sales. Detached homes are the priciest at a median of £745,000, while terraced homes are the most affordable at £350,000. Over the past year, semi-detached homes moved the most (+76.1%). New-build homes were 14.3% of recent sales, a share that is falling.
These figures track the median of prices actually paid, not a like-for-like index. A move can reflect a change in what sold — more new homes, or a different mix of house types and sizes — as much as any change in what a given home is worth.
| Type | Median | 12-month change | Sales |

Change compares the median for the last 12 months with the 12 months before.
New-build homes were 14.3% of sales in the latest year, and the share is ▼ falling over the period — a marker of how much new housing is being built here (not a price forecast). See the new-build chart above.
How these figures are calculated. Year-on-year change compares the median sold price over the most recent 12 months of data with the 12 months before it. We use the median, not the average, so a few unusually high or low sales don't distort it. Because HM Land Registry data lags — sales take time to be registered — the most recent month or two are provisional and tend to revise upward. Figures track the mix of what actually sold, so they are not a like-for-like index. The same method is used across this site, so an area's figure here matches its ranking in investment trends.
