Price per square foot

Knowing the average house price in Keynsham is not much use. However, knowing average price per square foot can be quite useful. Price per sqft allows some comparison between properties of different size. We define price per square foot as the sold price divided by the internal area of a property:

£ per sqft = price ÷ internal area
E.g. 39, Unity Road, Keynsham, sold for £400,000 on Mar-2024. Given the internal area of 1,076 square feet, the price per sqft is £371.

England & Wales have been officially metric for many decades. Convert this site to square meters.

The chart below is called a histogram, it helps you see the distribution of this house price per sqft data. To make this chart we put the sales data into a series of £ per sqft 'buckets' (e.g. £353-£371, £371-£390, £390-£408 etc...) we then count the number of sales with within in each bucket and plot the results. The chart is based on 206 sales in Keynsham (BS31 1) that took place in the last two years.

You can see the spread of prices above. This is because although internal area is a key factor in determining valuation, it is not the only factor. Many factors other than size affect desirability; these factors could be condition, aspect, garden size, negotiating power of the vendor etc.

The spread of prices will give you a feel of the typical range to expect in Keynsham (BS31 1). Of the 206 transactions, half were sold for between £333 and £431 per square foot. The median, or 'middle', price per square foot in 'BS31 1' is £378. Notably, only 25% of properties that sold recently were valued at more than £431 sqft. For anything to be valued more than this means it has to be more desireable than the clear majority of homes.
