From there on the street, as carried forward in 1820-4, proceeded more directly, but with great variety in the individual façades—one terrace of houses over shops (1820-1) was by Soane. There were also special pavilioned structures to phrase several slight changes in direction and to mark the openings of intersecting streets. At Regent (now Oxford) Circus a second circle, similar to that at Piccadilly but elaborated by Nash with a Corinthian order, marks a major cross artery. Above this the street continues quite straight for a little way; then comes another sharp leftward shift in the axis. There Nash placed his All Souls’ Church, which was built in 1822-4. Its curious fluted steeple still rises through the colonnade that crowns the tower to provide a pivot by which the eye is carried around the sharp corner. Almost at once another right-angled turn leads into the broad pre-existing esplanade of Adam’s Portland Place. From here on all is formal again as at Waterloo Place. At the upper end, between the top of Portland Place and the Park, was to be a large residential circus. Of this only the two southern quadrants were built—one of them the earliest portion of the whole scheme, initiated at the very start in 1812. As executed, there are above this—for this part of the scheme is all extant—two regular terraces facing each other across Park Square. In 1813, as has been said, Nash succeeded Wyatt in the Surveyor-General’s office; but it was in the role of private entrepreneur rather than as an official that he executed the Regent Street scheme, hazarding his own rising fortune and using every device of subleasing to carry the project through. This he accomplished in the relatively short period of fifteen years, even though the renewal of the war held up execution for several years immediately after the start. Of all this nothing remains below Portland Place but the planning and All Souls’. However, in the district east of Lower Regent Street, the Royal Opera Arcade still exists behind New Zealand House and, much larger and more conspicuous, the conventional temple portico of the Haymarket Theatre of 1821 stands at the end of what is now Charles II Street.
