I'm LOLing along with you notmorecraft. So jealous of the US lot sizes.
We're in a semi-detached (not even sure if you have that in the US - we are attached on one side to our neighbours) 2 storey house providing a grand total 750 sq feet of accommodation.
Our back garden/'yard' is about 30 feet by 25 feet (which is about double the size of most in this area, since we are a corner plot sort of on the dividing line between suburban and city centre in location)
I dream of American-style houses and outdoor spaces!! :-)
