Cornwall Terrace: the world’s most expensive row of houses goes on sale

The world’s most expensive row of terraced houses has gone on sale for a collective, wallet-busting price tag of around – £400million.

Uber-exclusive Cornwall Terrace, Regent’s Park, London consists of eight double-fronted mansions each with an asking price of between £29 and £60million.

But despite the sky high price and having to pay up to £2.5million stamp duty – Cornwall Terrace is in the City of Westminster – where residents pay the capital’s second lowest council tax bill.

Estate agents describe Cornwall Terrace as a ”rare convergence of provenance, history and grandeur”.

The terrace was designed by Royal architect Sir John Nash as part of the Prince Regent’s – later King George IV – plans for the 19th century masterpiece Regent’s Park.

Overlooking the park’s rowing lake, Cornwall Terrace’s double-fronted mansions belonged to the British nobility for 150 years before being occupied by commercial concerns.

Developers Oakmayne purchased the terrace two-and-a-half years ago and employed a group of renowned interior designers, supervised by English Heritage and The Crown Estate, to give the properties a tasteful makeover.

Each home took 83,000 man-hours to create with one whole year alone spent hand-digging two-metres beneath the original basement to create two extra floors.

The first two properties have come onto the market with a price-tag of £29 and £39 million respectively.

But the remaining six properties will be marketed next year with one unidentified mansion expected to cost a staggering £60 million.

For the same price, you could purchase 2,097 house on the UK’s cheapest road in Fernhill, Wales or 162 ‘average houses’ at a cost of £246,000 each.

Prospective clients have even enquired about the possibility of purchasing TWO properties and turning them into a deluxe single £100MILLION dwelling.

Ranging from 8,000 to 14,000 square feet, the Grade 1 listed mansions have between five and seven bedrooms and combine London’s rich architectural heritage with state-of-the-art technology.

The main entrance room of each property is described as being of ”embassy proportions” while each master bedroom is ”the size of your average apartment”.

All properties have oiled and polished hardwood floors and doors, handcrafted Italian marble floors alongside period fireplaces, cornices and other decorative detailing.

They also boast a silent hydraulic elevator and multi-room iPad-controllable audiovisual and lighting systems.

Each property is offered with an accompanying two-bedroom mews for staff and a ”Bentley-sized armour-plated garage” while each mansion benefits from a spa and gym.

The largest property – to be sold next year – also boasts a ball room and swimming pool complex
