Square footage costs money. But exactly how much varies dramatically across Britain. Zoopla's got the measure on where you can get the most floor space for your cash.

What’s the latest?

Ever wondered how much square-footage you could afford and where? Zoopla teamed up with its data company, Hometrack, to size up the cost of British homes based just on this measure.

We found London's Kensington and Chelsea to be the most cripplingly expensive. Just one square foot of floorspace within the royal borough (about enough room to stand the kitchen bin on) costs a staggering £1,328 – that's 29% more than five years ago.

The City of Westminster – home to the Houses of Parliament and Buckingham Palace – came a close second, with average costs sitting at £1,093 for each square foot.

And you’ll need to head to Blaenau Gwent in South Wales (see map below), to get the most space for your money. Homes in the area cost an average of £79 per square foot – up 10% since 2012.

Across Britain as a whole, the average cost per square foot of property is £211, which is 26% higher than five years ago.Above: A generous three-bedroom terraced house in the market town of Brynmawr, Blaenau Gwent, on the market for £139,950Above: A super-skinny two-bedroom mid-terraced Victorian cottage in Kensington, on the market for £995,000

What about by region?

In regional terms, house hunters can achieve the most value in the north east, where the average price per square foot now stands at £124. It has risen by just 3% over the past five years.

Wales is the second cheapest region, with the average square footage currently costing £137, a 9% rise since 2012.

And, with a staggering 54% hike in costs over the last five years, average square footage in London is the least affordable at £496.
