This is a house in Mosman Park by Rodney Alsop, from 33-34. Its a beautiful house in Spanish mission/revival style, and very classical. A very beautiful house, great proportioning, and colours and siting. Wonderful views, outdoor terrace and spiral staircase to balcony. I am not very familiar with the Spanish style, so I cant really say to much more about it intelligently, but it truly is amazing, perfect for its setting.
Thanks Janine for Details!
