These are further sanctified by the recent additions to the architectural excellence of buildings, a fusion of the traditional and modern architecture which are mostly post 1962, after Thimphu became the Capital of Bhutan and opened up for tourism under various Five Year Developmental Plans. The buildings under this category are the National Institute for Zorig Chusum, National Library, National Assembly cum SAARC Building, National Institute for Traditional Medicine, National Textile Museum, Voluntary Artists Studio, Royal Academy of Performing Arts, Telecom Tower and many more. The residential buildings in Thimphu have also undergone change in their construction methods without sacrificing the traditional Bhutanese designs said to be "reminiscent of Swiss Chatels."
