Question: What title that is currently only given in conjunction with that of Prince of Wales is also the namesake of one of the neo-classical terraces in Regent's Park, London?

full_context: Document 1: Earl of Chester: The Earldom of Chester (Welsh: "Iarll Caer") was one of the most powerful earldoms in medieval England, extending principally over the counties of Cheshire and Flintshire. Since 1301 the title has generally been granted to heirs-apparent to the English throne, and from the late 14th century it has been given only in conjunction with that of Prince of Wales.
Document 2: Carlton House: Carlton House was a mansion in London, best known as the town residence of the Prince Regent for several decades from 1783. It faced the south side of Pall Mall, and its gardens abutted St. James's Park in the St James's district of London. The location of the house, now replaced by Carlton House Terrace, was a main reason for the creation of John Nash's ceremonial route from St James's to Regent's Park via Regent Street, Portland Place and Park Square: Lower Regent Street and Waterloo Place were originally laid out to form the approach to its front entrance ("illustration, right").
Document 3: Arthur, Prince of Wales: Arthur Tudor (20 September 1486 – 2 April 1502) was Prince of Wales, Earl of Chester and Duke of Cornwall. As the eldest son and heir apparent of Henry VII of England, Arthur was viewed by contemporaries as the great hope of the newly established House of Tudor. His mother, Elizabeth of York, was the daughter of Edward IV, and his birth cemented the union between the House of Tudor and the House of York.
Document 4: Princess of Wales: Princess of Wales (Welsh: "Tywysoges Cymru" ) is a British courtesy title held by the wife of the Prince of Wales, who is, since the 14th century, the heir apparent of the English or British monarch. The first acknowledged title holder was Eleanor de Montfort, wife of Llywelyn ap Gruffudd. It has subsequently been used by wives of post-conquest princes of Wales.
Document 5: Duke of Rothesay: Duke of Rothesay (Scottish Gaelic: "Diùc Baile Bhòid" , Scots: "Duik o Rothesay" ) is a dynastic title of the heir apparent to the British throne, currently Prince Charles. It was a title of the heir apparent to the throne of the Kingdom of Scotland before 1707, of the Kingdom of Great Britain from 1707 to 1801, and now of the United Kingdom of Great Britain and Northern Ireland. It is the title mandated for use by the heir apparent when in Scotland, in preference to the titles "Duke of Cornwall" (which also belongs to the eldest living son of the monarch, when and only when he is also heir apparent, by right) and "Prince of Wales" (traditionally granted to the heir apparent), which are used in the rest of the United Kingdom and overseas. The Duke of Rothesay also holds other Scottish titles, including those of Earl of Carrick, Baron of Renfrew, Lord of the Isles and Prince and Great Steward of Scotland. The title is named after Rothesay on the Isle of Bute, Argyll and Bute, but is not associated with any legal entity or landed property, unlike the Duchy of Cornwall.
Document 6: Principality of Wales: The Principality of Wales (Welsh: "Tywysogaeth Cymru") existed between 1216 and 1536, encompassing two-thirds of modern Wales during its height between 1267 and 1277. For most of its history it was "annexed and united" to the English Crown except for its earliest few decades. However, for a few generations, specifically the period from its foundation in 1216 to Edward I's completion of the conquest of Wales in 1284, it was "de facto" independent under a Welsh Prince of Wales, albeit one who swore fealty to the King of England.
Document 7: Chester Terrace: Chester Terrace is one of the neo-classical terraces in Regent's Park, London. The terrace has the longest unbroken facade in Regents Park (about 280 metres).

Document 8: Cumberland Terrace: Cumberland Terrace is a neoclassical terrace on the eastern side of Regent's Park in the London Borough of Camden, completed in 1826. It was one of several terraces and crescents around Regent's Park designed by the British architect John Nash (1752–1835), under the patronage of the Prince Regent (later George IV). The terrace was to stand opposite the Prince's proposed palace in the park and was therefore of particular importance in the scheme. It was named after the King's younger brother, the Duke of Cumberland.
Document 9: Mecklenburgh Square: Mecklenburgh Square is a Grade II listed square located in the Bloomsbury area of central London. The Square and its garden were part of the Foundling Estate, a residential development of 1792–1825 on ﬁelds surrounding and owned by the Foundling Hospital. The Square was named in honour of King George III’s Queen, Charlotte of Mecklenburg-Strelitz. It was begun in 1804, but was not completed until 1825.

It is situated at the park's southwest corner, near Baker Street, between York Terrace and Clarence Terrace, within the park's Crown Estate development. Cornwall Terrace was part of the scheme of the Prince Regent, later King George IV, to develop grand housing in Regent's Park.

Terry designed each house in a different classical style, intended to be representative of the variety of classical architecture, naming them the "Veneto Villa", "Doric Villa", "Corinthian Villa", "Ionic Villa", "Gothick Villa" and the "Regency Villa" respectively.
Document 15: Carlton House Terrace: Carlton House Terrace is a street in the St James's district of the City of Westminster in London. Its principal architectural feature is a pair of terraces of white stucco-faced houses on the south side of the street overlooking St. James's Park. These terraces were built on Crown land between 1827 and 1832 to overall designs by John Nash, but with detailed input by other architects including Decimus Burton. They took the place of Carlton House, and the freehold still belongs to the Crown Estate.
