Lost

I'm sceptical that there's ever much new in wayfinding and signage proposals. Design company The Chase, set up initially by Ben Casey in Manchester, has come up with coloured routes (last abandoned at The Barbican)  to navigate around MediaCityUK, thus....

And they've come up with the wheeze of using two letter codes for each of the buildings, which will form the last two digits of their postcode.  Thus the Pie Factory will be M50 2PF ( "go through the green, take the yellow, and turn right at the orange").  The Garage becomes M50 2TG ("go through the green and white to the blue, then turn right at the red.  Or go through the green to the white, cross the green to the white again and turn left at the red - not sure which is shorter").

Some purity has gone from the concept.  The Studio Block, which ought to be SB, has become HQ, which I'm sure leaves the BBC cold.  The Holiday Inn becomes HT, cos you can't use "I".   Block of flats "Number One" can't, for the same reason, be NO, so one presumes BB means Big Building (as in "Go through the green to the purple and look for the Big Building. Over there." [points]).

It partly explains Peter Salmon's rather dull choices in naming the three BBC blocks Bridge House, Quay House and Dock House.  The postcodes are BH (neat), QH, and, hang on a minute, LH ?
