It's the Copenhagen Building Blocks pattern, but it reminds me a lot of Dutch canal houses.
Very versatile because you can combine any type of house or section of house in whatever colour you prefer (or happen to have available) and put it together to your own liking.
I used a lot of the yarn I use for the bunnies (Sport or DK weight) on needle 2.75mm
I made 12 houses (6 for each side) and it fit perfectly around an Ikea pillow 50x50cm.
Pretty pleased with the end result.
