London, where he became a friend of
Samuel Johnson. In 1749, when Sir
Christopher Wren's drawings were sold, Gwynn obtained Wren's plan for the rebuilding of the
City of London, and published it, adding some comments of his own. It was passed in June of the same year. in which he criticised the loose control over building in the West End, saying that "the finest part of town is left to ignorant and capricious persons", and called for development to be controlled by a general plan. He made more than a hundred suggestions for improvements to the capital. the construction of a "St, George's Bridge" in the position where
Waterloo Bridge was eventually built; a "King's Square" on the site of the
Royal Mews However proposals similar to many of Gwynn's were eventually implemented; Gwynn influenced the drafting of the
Building Act 1774 and others at
Atcham (1769–71),
Llandrinio (1769-1775) and
Worcester (1781) He was one of the foundation members of the Royal Academy in 1768,
