Britain’s biggest homes for sale: Devon country house vs London mansion

The biggest properties for sale on the open market in Britain – both in and outside of London – have been exclusively revealed to us by Zoopla

The largest home on the property listing website is in Devon, in the town of Ottery Saint Mary, and at 22,211 sq ft it’s almost double the size of the 12,451 sq ft mansion in the capital.

Yet the price tag of the country house in Devon – said to be where Oliver Cromwell declared civil war –  is significantly less at £5.95million, costing just over a third of the £15.95million one in North London’s Highgate.

For £5.95m you could get more than 22,000 square feet of country house with 21 acres of grounds in Devon 

Whereas £16.95million buys a 12,500 square feet seven-bedroom mansion on London's Courtenay Avenue

The seven-bedroom London pile is on Courtenay Avenue, which was recently named the second most expensive street in Britain and is close to Hampstead Heath. It comes with half an acre gardens – a sizeable chunk of land for a home in the capital.

But the Devon property boasts 21 acres, ten bedrooms, parkland and woodland, and comes with what the estate agent describes as ‘the fascinating Cromwell Fairfax Room where it is believed Civil War was declared in the 17th Century’.

The average price of a home in Ottery, where it is situated, is £433,981, which is up £28,052 on a year ago, according to property website Zoopla.

By contrast, the average price of a home in Courtenay Avenue is £20,510,200, but that is down £108,741 compared to a year earlier, as buyers’ pandemic desire for the country tops demand for the capital.

We take a look inside both properties…
