Living in a National Park boosts your house price twice as much as an Area of Outstanding Beauty, new research has found.
Homes in National Parks cost 25pc more than identical properties in other areas, but for AONBs the premium is only 13pc, according to Nationwide Building Society.
Andrew Harvey, of the firm, said that limitations on planning in National Parks was key. "Development is controlled with limited new housing construction," he said.
The biggest appeals for buyers are beautiful scenery and having very few neighbours. The Yorkshire Dales, for example, covers 841 sq miles and is home to 23,700 people - it is an area 39pc larger than Greater London with a 376th of its population.
Isolation, green space and an outdoor lifestyle have become bigger priorities for buyers since the pandemic began. Since 2020, the price premium for property within National Parks has jumped by five percentage points, up from 20pc.
In cash terms, the 25pc premium means an average £270,500 UK property would be worth £67,600 more if it was in a National Park.
National Parks also have a so-called "halo effect", boosting the value of homes within a three-mile radius by 7pc.
AONBs, which are home to more than one million people, are conservation areas that rely on planning rules to maintain the landscape, but they do not have specific legal planning powers, unlike National Parks.
They are also typically less famous than National Parks, Mr Harvey said.
But while the premium for National Parks might be larger, it is AONBs - which can be closer to cities and amenities - that have the most expensive homes.
The 220 sq mile New Forest, which is home to 35,500 people and encompasses the villages of Ashurst, Lyndhurst and Brockenhurst, was Britain's most expensive National Park, with average house prices at £650,000.
It was followed by the South Downs, the Lake District and the Brecon Beacons, where homes cost £450,000, £380,000 and £350,000 respectively.
Homes in Britain's most expensive AONB, however, cost £100,000 more than in the New Forest. The average property price in the Surrey Hills - a 163 sq mile area that is home to 37,000 people - was £750,000.
It was followed by the Chilterns, where the average home cost £613,000. In the High Weald and the Cotswolds, homes cost £490,000 and £463,000 respectively.
