Exercise 3 - Lechner, Kos and the less national building (sample answer) Lechner: ceramic ornament, Eastern and folk motifs, often on large urban buildings. Kos: steep roofs, timber and rustic detail from vernacular and Transylvanian building, often on smaller or suburban projects. Less national: the Gellert Hotel and the Liszt Academy are in a Secession style current across central Europe and do not set out to be Hungarian in subject. Either may be argued, so give a reason.
