From City Tech you would walk to The Supreme Court. From there would walk down Pierrepont St. past the Brooklyn Historic Society. There you wil spot a cathedral and a white building across the street from it. The juxtaposition is the old brick cathedral and the new marble building. The contrast between the two is that the cathedral is old fashioned and historic meanwhile the white building is more contemporary. It may be a house for someone to live in.
The two buildings are each striking, and strikingly different. It would be good to do a tiny bit of research to find out what that building is–I can help you if you can’t find it. You might then be able to add to your project by considering the different uses for the buildings as well as their aesthetic, architectural, and construction differences.
