Homing Pigeon?

I noticed this chap a few days ago while limping towards Sainsburys.  I was impressed by the efforts to hinder pigeons, of which there are many sleeping on the roof here overnight, from perching on the windowsills.  I am always impressed by birds as they consider the many ways in which they can not only make it through the day, but also improve their lives by simple actions.  Here, one bird, by the simple action of smashing the window, possibly while flying at high speed with his eyes closed, has gained entry to the top floor of this very ancient building.  

This building stands in what is called 'Little Square.'  This marks the spot where the early market first arose over 800 years ago.  This came about by the Bishop of London, who owned this side of the town, persuaded King John, he of ill-repute, to allow a market here weekly.  King John considered for a few moments the tax raised by such a market, his debts obtained by fighting very badly when claiming France as his kingdom, and allowed the market to begin, and added one down in Chelmsford around this time also.  The tax played on his mind I reckon, more than the cabbages available on the ground.

This building, wood and plaster, has stood here for a great many years, I suspect several hundred, but I have not got that information to hand.  

The block of houses contains four shops on the ground floor, as a market should, most are in good condition still, however, the one at the end, where the pigeon roosts, is somewhat less tidy.  There is a shop at a the bottom, which I think is now closed.  A first floor for accommodation for those who like to 'live above the shop,' and this top floor for pigeons to look down on you.  Like too many shops in the town life appears far from this one.  I think the owner, or tenant, has another along the way, but I could be wrong.  Either way, someone needs to look into the building, accommodation and a shop all in one, in the centre of town, just off the main drag?  Someone will make money here surely?
