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 £29m
and £39m respectively.

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

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

Ranging from 8,000 to 14,000 square feet, the Grade I-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 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.
