That sounds like shite behavior from the council but (I know this is cliche) it is physically painful for me as a German to look at this wonky-ass stairs ^__^
Living in the UK atm where I have plenty of opportunities (on council-build stairs!) to exaxtly know absolutely weird it feels to walk down stairs where every step is a different length (and sometimes also height), like stumbling through a nightmare ...
Still better than no stairs, obviously ...
