Having been articled to Henry Poston of Lombard Street, London in 1892, he remained with Poston as his assistant until he started an independent practice in London in 1905.[1]
His son William Sydney Trent (1903-1944) was also an architect. When his father became a full-time employee of PCT, his son took over his private practice, retaining him as a consultant. However, he joined Gaumont British in 1932 to help his father with the huge increase in work with the advent of talking pictures.[1]
