 In the 1920s a large and well-proportioned neoclassical extension was built up to the corner of St Mary Street and Heol-y-Cawl.A unique result of this extension was that Bethany Chapel, built on the site of an earlier chapel in 1865, was absorbed into the fabric of the building and its frontage was incorporated into the interior and is still visible in the store today, fronting onto the men's Aquascutum department.Howells Department Store was a family-run business, owned and managed by the family of James Howell.
