 A specialist in prefabricated timber houses, learnt from Finland, among Mardall's notable works are housing for Stevenage and Harlow new towns, as well as the Finnish Lutheran Missionary Church in London (1958).In more recent times, of equal significance worldwide as actual buildings designed by Finnish architects has been the architectural theory - and prolific amount of writing published in several different languages - by Finnish architect and theorist Juhani Pallasmaa, with such books as "The Eyes of the Skin – Architecture and the Senses" (2012), "Understanding Architecture" (2012) and "The Thinking Hand" (2009), and Finnish architecture theorist Kari Jormakka, with such books as "Eyes That Do Not See" (2012), "Heimlich Manoevres - Ritual in Architecture" (1995) and "Basic Design Methods" (2007).The first prominent architects in Finland came from abroad, most notably Carlo Bassi from Italy and Carl Ludvig Engel from Prussia in the 19th century, designing in the neoclassical style.
