Filling the gaps

Hint 1: A school of art and architecture in Germany between 1919 - 1933
Hint 2: Its traces are extremely rare in this island and they are, in their majority, found in Paphos between the two gardens used only on Sundays
Hint 3: Mr. Pantelis Kouros was working in this building [his exact occupation is yet to be defined] before becoming a by-stander or stand-by Mr. Glafkos Clerides. Neither Mr. Kouros nor Mr. Clerides have any direct relationship with neither the school in Germany nor the gardens in Paphos.
