Passage: Only two of the houses envisaged were finally built: doctor Trias i Domènech’s House and what is nowadays Gaudí House-Museum which had to serve as a lure for potential land-buyers. These houses were added to the old house, that already existed in the place and whose owner was Eusebi Güell himself.

Question: What is the name of Dr. Trias i Domenech's residence currently?
Gaudí House-Museum
