Something very common for New England homes are the old Victorian houses that have been renovated into multiple family homes, and all the old textile mills converted into apartments. The mill apartments all have very high ceilings, are usually very poorly heated and cooled, and the outside wall was brick, so you couldn't ever hang anything on the walls. The mill apartments are usually cheap (relatively, nothing in New England is cheap), and are a lot of peoples first apartments when moving out of home. The Victorians are also usually poorly heated and cooled, because the buildings are so old, they are not usually retrofitted with modern heating. A friend of mine in grade school lived in one, and I remember being completely fascinated by the dumb waiter (which we were absolutely forbidden to play with!). New England homes also have a very steep roof to let the snow and ice slide off (every year there is still a building that collapses due to snow weight), and very steep wooden stairs on the outside of the buildings that you swear will fall every time you use them.
I like the look of your row houses, I know we have some in America, I've seen pictures of houses like them in San Francisco. I think the show Full House was supposed to take place there, and I remember being fascinated by those houses connected like that on the hill.
