Cornwall Terrace (also 1-21 Cornwall Terrace) is a Grade I listed building of consecutive terraced mansions overlooking Regent's Park in the City of Westminster, London. It is situated at the park's southwest corner, near Baker Street, between York Terrace and Clarence Terrace,[1] within the park's Crown Estate development.[2] Cornwall Terrace was part of the scheme of the Prince Regent, later King George IV, to develop grand housing in Regent's Park.[3][4]


Cornwall Terrace

Cornwall Terrace was one of the earliest buildings constructed in Regency Park,[5] and the park's first completed terrace.[6] The terrace was constructed, between 1821 and 1823, by the property developer James Burton, to a Greco-Roman design by Decimus Burton and Sir John Nash.[7][8][2] After the Second World War, the terrace was refurbished. It became a Grade I listed building on 9 January 1970.[2]


Architectural features give the building a regal appearance. The ground story is rusticated, while the principal stories are of the Corinthian order. The terrace block originally consisted of 19 houses, with Nos. 20 and 21 constructed later from the south pavilion. The original design contained three main storeys, an attic storey, pavilions, mansards, and basements, as well as shallow porches, square headed doorways, shallow architraves, first floor cornices, balustraded parapets, wings with Venetian-style windows, cast iron balconies, and spearhead area railings.[2] There are fluted shafts, well proportioned capitals, and an entablature,[5] No. 1 was adorned with a caryatid-bow.[6] At the westernmost end, No. 10 was provided with bow windows which continued up over two stories.[2]

No. 1[edit]

No. 1 Cornwall Terrace is 21,500 square feet (2,000 m2) in size.[4] It has seven bedrooms, nine bathrooms, a hydraulic elevator, and 11 reception rooms; it is described as a "Trophy Home".[4] The interior consists of hardwood floors and doors, Italian marble, period fireplaces, cornices,[3] a spa, heated swimming pool set in Portland stone, a dining room which can accommodate 16 people, and light switches controlled by an iPad.[9] No. 1 was the home of the New Zealand High Commissioner from 1955 until the mid-1970s;[9] Sir Clifton Webb was the first New Zealand High Commissioner to live here. In January 1975, hippie groups moved in and squatted the premise along with the entire terrace, and the Divine Light Mission opened up a health food store.[9][10] After the hippies left, later in the same year, it became the headquarters of British Land,[9] a large property development company.[6]

By 2002, it belonged to telecommunications entrepreneur Charles Wigoder.[9] Oakmayne Developers, who bought the mansion in 2007, refurbished it; the refurbishing was overseen by the English Heritage and the Crown Estate, to give the property an appropriate makeover. During the refurbishing process, two extra floors were added in the basement by digging 2 metres (6 ft 7 in) below the original basement.[3] In November 2012, the mansion was on the market for £100 million, making it one of the most expensive properties in the world,[9] and in March 2013, it was bought for £80 million by property mogul Marcus Cooper.[11]
