In his discussion of new materials used in the interwar period, Gavin Stamp includes Auguste Perret, pioneer of reinforced concrete, and his spectacular Église Notre-Dame, Le Raincy (1922-23). However, he makes no mention of St Andrew's Church (1931) in Felixstowe, thought to be the first reinforced concrete church in the UK, a clever mix of modernity and medieval Suffolk wool church, clearly influenced by Perret. The lead architect was Hilda Mason (1897-1955) who worked with the younger, but later better-known, Raymond Erith (1904-73). This important church is Grade II* listed but now in poor condition.
