Makovecz is one of the most prominent proponents of organic architecture. As such, his buildings attempt to work with the natural surroundings rather than triumph over them. Frank Lloyd Wright and Rudolf Steiner are both strong influences, as is traditional Hungarian art.
Makovecz's key works include the Sárospatak Cultural Center (completed in 1982), the Visegrád Sports Hall (1985), the Town Hall and Commercial Center of Dunaszerdahely and the Kakasd Community Center (1996). His group designed the buildings of the Piliscsaba campus of Pázmány Péter Catholic University. In addition, he also designed Hungary's pavilion for the 1990 World's Fair in Seville, Spain.
