London

[WannGLondon]

I am currently working on a city loosely based on London, England.
I was wondering if anyone could help me find those beautiful white terraces (not Gascooker's, please) located in affluent areas in the city, like Belgravia and Kensington. I am having a hard time completing my city without them, please help.

This is what my current city looks like;

As you can see the area below the large park is empty and that is where i was planning to have the white terraces.
Please help me complete my wanna-be London city.
