Some cycle parking/hoops down the lower end of the centre, particularly outside the Post Office (
), would be a good improvement!
Also, why not some kind of central information board at the foot of Market Street, housing a map of Marple District Centre with all the shops named or numbered (our own version of what larger shopping centres, eg. The Trafford Centre have), and highlighting Memorial Park and the route up Church Lane to the canal? I know Marple isn't that big, but it might be useful for those new to the area or who don't want to walk up and down the dead-ends of Derby Way, etc. to see what's actually here. Perhaps it could have advertising space for local businesses, to fund the installation and upkeep?
The repaving/regeneration a few years ago improved the look of the street massively, but I always find the actual main entrance to the street here to be rather ugly, with the back of a phone box and that huge CCTV camera column providing the only focal points. It's not really a place anyone wants to dwell at the moment.
