I am writing a story set in England in the 1970s, and I wondered if anyone knows of where I could find British style textures and models. I am particularly looking for things like Victorian style lamps, but can't find any on Google SketchUp.

I have two questions. The first is, how do you raise the ground level for a hill terrain?
And how would you make a walkout basement?

Does anyone know of a website that has 1970s style textures and furniture?
