not a problem?
sunday evening unsecured glass windows stacked up outside the building they are renovating for a family home, old wood fittings with large nails protruding!
not a safe environment for anyone dropping their kids off monday morning.
Your original point was about traffic; I repeat - it isn't a problem. I walk past the building several times a day and I have to say that I don't feel unsafe! At the times that I drive, it doesn't present any new problems. I suspect that its youthful clientele are unlikely to be walking there themselves without a responsible adult to hold their hand. It's a lot safer than crossing Station Road in the rush hour.
I don't think that it is any worse than any other building renovation. I'm pleased that the newer part of the building is being used for (a much-needed) purpose, and glad that the older part is to be looked after.
I don't know the owners, but they have leafleted the whole of Hollins Green Road explaining what they are aiming to do; it seems entirely reasonable. Their business seems far more useful to the community of Marple than some of the niche-market shops that have opened (and closed) in the centre recently.
