Are block sizes in Darch big enough for a real backyard?

I guess it really depends on what you call a 'real backyard'. In my opinion, they are not big enough for that unless you buy a 600m block and put a tiny house on it. Most don't have any yard to speak of, but if you have toddlers then you could make do for a while but no bike riding and hitting balls around though. Or if you want a nice garden then I'd look elsewhere for space to do it on a bigger scale. Big dogs not so great for them to run around either.
