Happurachige Premadasa Wijayasiri, as recorded in the Architectural Association’s Diploma Roll Book, is a Sri Lankan student who attended the Department of Tropical Architecture in 1969-70 and subsequently earned a post-graduate certificate. In an apparently typographical error, the student register lists him as “H. Wijasiri”. An architect with the same name – again, apart from a slight typographical error – appears in the 2015 Gazette Extraordinary of the Democratic Socialist Republic of Sri Lanka, under the section listing registered architects. No other information about him is available.
