How did Johann Bernhard Fischer von Erlach create a new type of country house?

Johann Bernhard Fischer von Erlach created a new type of country house by synthesizing the most significant advancements in suburban architecture since the 16th century.1

He achieved this by merging two distinct architectural traditions:
* French Baroque: He incorporated the concept of the country palace composed of multiple joined pavilions.1
* Renaissance: He integrated the classically inspired villa style, characterized by the work of Andrea Palladio and surrounded by low, detached wings.1

To these elements, Fischer added the powerful, curving forms of the Roman Baroque style—influenced by his training under Gian Lorenzo Bernini—to provide his designs with a more dynamic structure. A hallmark of this new type of country house was the inclusion of a spacious oval hall at the center of the floor plan, a feature exemplified in his designs for Schloss Neuwaldegg and Schloss Engelhartstetten.1
