Document 14: King and Queen, Brighton: The King and Queen (also known as Ye Olde King and Queen and The King and Queen Hotel) is a pub in the seaside resort of Brighton, part of the city of Brighton and Hove. The present building, a "striking" architectural "pantomime" by the prolific local firm Clayton & Black, dates from the 1930s, but a pub of this name has stood on the site since 1779—making it one of the first developments beyond the boundaries of the ancient village. This 18th-century pub was, in turn, converted from a former farmhouse. Built using materials characteristic of 16th-century Vernacular architecture, the pub is in the Mock Tudor style and has a wide range of extravagant decorative features inside and outside—contrasting with the simple design of the neighbouring offices at 20–22 Marlborough Place, designed a year later. English Heritage has listed the pub at Grade II for its architectural and historical importance.
Document 15: Union Chapel, Brighton: The Union Chapel, also known as the Union Street Chapel, Elim Free Church, Four Square Gospel Tabernacle or Elim Tabernacle of the Four Square Gospel, is a former chapel in the centre of Brighton, a constituent part of the city of Brighton and Hove, England. After three centuries of religious use by various congregations, the chapel—which had been Brighton's first Nonconformist place of worship—passed into secular use in 1988 when it was converted into a pub. It was redesigned in 1825, at the height of Brighton's Georgian building boom, by at least one of the members of the Wilds–Busby architectural partnership, Brighton's pre-eminent designers and builders of the era, but may retain some 17th-century parts. It has been listed at Grade II in view of its architectural importance.
